In an attempt to clear up some confusion and provide a little education on the not-quite-fascinating subject of license servers, we'll go over various licensing scenarios and what is involved, server-wise.
Summary: “The integration of RLM helps us not only provide floating license capability, but also allows us the ability to license new modules separately, such as the new chemistry module,” explained Scott Thibault, CPFD Software’s Vice President of Sales & Marketing. “Responding to market conditions, to our client’s detailed technical needs, is the heart of our business.”
CPFD Software’s Barracuda
CPFD Software’s Barracuda v14.3 Allows Simulation of Particle-Fluid Flows with Full Thermodynamics and Chemical Kinetics
In the fourth quarter of 2009, CPFD Software LLC, the creators of the Barracuda simulation package for particle-fluid systems, released the latest version of their sophisticated engineering software for modeling 3-dimensional chemical, thermal, and flow dynamics in gas-solid and liquid-solid systems
Barracuda v14.3 Includes:
- NEW Chemistry Module for modeling the homogenous & heterogeneous chemical reactions inside fluidized bed reactors.
- Gas Release of an entrapped gas or liquid within a solid.
- Liquid Injection Module that simulates liquid spray coating of particles such as fluidized-bed cokers.
- Wear Model that allows component wear to be reported on annualized basis.
- Reprise License Manager to allow floating licenses and full usage reporting
Barracuda is used by major oil & gas, chemical, petrochemical, and power equipment manufacturers for simulating, understanding, and optimizing the operation of fluidized systems. Common applications are FCC (fluidized catalytic cracking) reactors and regenerators, fluidized chemical reactors, and CFB (circulating fluidized bed) burners in coal-fired power plants, and both coal and biomass gasification reactors.
These critical gas-particle and liquid-particle systems are key elements in moving from a batch process to a more profitable continuous manufacturing process. When added to the detailed fluid/particle flow and thermodynamics, the new full chemistry modeling in this latest Barracuda release completes the simulation package, providing an important enabling technology for designers and operators of this equipment. Barracuda is capable of modeling this equipment at lab scale, pilot scale and full production scale with detailed chemistry at every stage.

Licensing Customized to our Needs
Licensing for us was a very important issue, and we have been using RLM since 2007 with great success. Our software Direct Transport Compositor is a cluster application, running on multiple nodes in parallel. It supports two kinds of nodes: the Display Nodes, which are connected to the displays, and the Rendering Nodes, which are in charge of the actual computation of the image. The way we charge our customers depends on the number of Display Nodes and Rendering Nodes they want to use at the same time on their system(s). We have chosen to use a centralized license server from which Direct Transport Compositor comes to check out dynamically the requested number of licenses. This allows our customers which have multiple systems to share and distribute the Display Nodes and Rendering Nodes licenses when they do not use all systems at the same time. This very flexible approach is very appreciated by our customers.

We've been lucky enough to be around software licensing for 20 years; combined, we have over 70 years of software licensing experience under our roof. It's safe to say that in that time we've seen it all, and then some. Whether it's enterprise end users wanting the best tools to maximize the usage of their valuable software assets, or software vendors wanting that next creative approach to licensing and selling their software, we've been there and done that.
Summary: “RLM offers a number of sophisticated solutions for implementing licensing strategies, and we have certainly not used all of the power of RLM. For us a key requirement was reliability and ensuring a painless experience for our end-users when having to deal with license issues. Previously, licensing was at times an obstacle to use and installation of our software. Since we made our switch to RLM things are much smoother and most importantly without pain for our end customers.”
Streamsim Technologies is a leading provider of high-end, reservoir flow simulation software based to the oil and gas industry. Companies use our products to manage and optimize oil & gas production from mature fields, specifically fields that are being produced with the aid of water and/or gas injection. Given the global nature of the industry, Streamsim supports customers all over the world.
The Switch to RLM
Streamsim’s move to RLM came in 2006, just as Reprise was launching its first version of RLM and we were facing and strong price increase from our previous supplier (SentinelLM). Two things were immediately apparent to us: a) Reprise came across as a small, nimble company that was going to support us anyway they could, and b) their pricing seemed reasonable and well tailored to a company like ours. The fact that they were the founding group were also the original architects of FlexLM was an added bonus. After some due diligence, we decided to switch.
We now have two products that are protected by RLM. The first is a numerical engine (3DSL) that has 5 modules that can be turned on & off and that run under Windows and Linux 32/64 bit environments. The second is a pure Java application based on the NetBeans platform that houses a number of options for allowing engineers to interpret results and make decisions based on results of 3DSL. RLM is our main way to turn options on and off, offering our clients an a-la-carte menu of choices.
Our clients have repeatedly demand three licensing features, all of which are extremely well served by RLM. The first is the ability to install network licenses that can be checked out by any engineer in the company and that are visible across the entire company network. The second is the ability to check-out/check-in roaming licenses onto laptops when engineers are off the network. And the third is the traditional standalone license. The ease of installation of the RLM server and its interface via a Web browser has resonated extremely well with our clients. In turn that reflects well on us. Recently, Reprise has added the ability to have a server that is platform independent, meaning that while we only support Windows/Linux a client can install a server on a different platform and our daemon will work there as well. That has given us flexibility and choice to our end-customers.
End User Acceptance and Support
There is always some pain involved when switching to a new licensing strategy and platform, and it did take us a bit longer than expected to get things right. However, the benefits have been dramatic. We receive next to no support calls for license issues or problems and our customers have extremely reliable access to our software on their networks. This allows us to concentrate on technical support of our own software as well focus on enhancing features important to our clients rather than having to field license support issues.
The odd times we do face an issue or are trying a new licensing strategy, Reprise has been extremely responsive and it is unusual if we don’t hear back within hours of email inquiry. Support has been prompt, reliable, and helpful.

“Before implementing RLM licensing, GEDCO was using a competing licensing product,” admitted Randy Kolesar, Manager for GEDCO Software Division. “We found the product support for this competing product to be poor and its licensing library did not support multiple platforms. Our evaluation of RLM found them to be extremely responsive to questions during implementation. We also found the RLM software to be very flexible in its configuration and support of multiple platforms. Consequently, we chose RLM for all our licensing options.”
GEDCO offers various licensing options for its software ranging from single node locked to floating multi-seat licenses running on multiple platforms. The licenses also contain multiple configurations based on the functionality purchased from the client. GEDCO uses the Reprise License Manager (RLM) to control which set of modules are enabled for the software.
The most important factors that GEDCO considered when selecting RLM were the support of floating and node-locked licenses and the ability to run on multiple platforms.

Summary: “For the sake of saving our license management resources, we decided to use a commercial licensing solution. It was a key issue that a new solution should have not only equivalent functions to the prior program but also portability between various platforms, simplicity to implement, robustness in actual use, and reasonable cost.”
About National Maritime Research Institute:
National Maritime Research Institute (NMRI), Japan, is the core research institute for ship technologies. It is implementing research on technologies for safe and efficient marine transportation, effective utilization of marine resources and spaces, and marine environment protection.
NMRI delivers various software products to the ship industry. “NMRI CFD” is a major product that is a powerful suite of CFD (Computational Fluid Dynamics) software. Computational Fluid Dynamics is a tool to simulate fluid flows by numerically solving the governing equation of fluid motion (the Navier-Stokes equation). NMRI CFD can estimate various elements of ship performance, such as resistance due to viscosity, waves generated by a ship hull, self-propulsion factors, etc. It is widely used in shipyards and design consultancies for evaluating ship performance in the design stage.
NMRI CFD is composed of three products, HULLDES, NEPTUNE and SURF. HULLDES is a grid generator which can make a structured grid around a ship hull easily and precisely. NEPTUNE is a flow solver which solves Navier-Stokes equations for a structured grid and it can calculate flow fields around ships rapidly. SURF is also a Navier-Stokes solver for unstructured/structured grids which can cope with complex geometry like an appended hull with a propeller shaft and a rudder. Our customers select the proper product from the suite as the situation demands. Customers need purchase only one or two products from the suite according to their own needs.
Licensing at NMRI
We had used a license management program developed in-house using the WIN32API. The program would check TCP/IP address, expiry date, software version, and computational grid size limits. But a growing number of customers increased the burden for us to control issued licenses. In addition, some customers wanted to use 64bit computers or Linux OS. For the sake of saving our license management resources, we decided to use a commercial licensing solution. It was a key issue that a new solution should have not only equivalent functions to the prior program but also portability between various platforms, simplicity to implement, robustness in actual use, and reasonable cost.
After researching several available licensing solutions from the above point of view, we decided to adopt the Reprise License Manager (RLM). It completely satisfies our demands. We usually issue a server-client type license to customers and occasionally issue a node-locked license for temporary use such as evaluation or demonstration for sales promotion. RLM allows us to spend our resources developing the core technology of CFD software. We believe RLM can help many independent software vendors enhance their own competitiveness with a sophisticated license management system.
