Release and Distribution of XPS, massive computation CFD-DEM software

Dear all,

We are pleased to announce the commencement of distribution for XPS (eXtended Particle Simulation), a new, coupled CFD-DEM tool.
This integrated numerical simulation software perfectly combines the unique product specifications of the GPU-based DEM solver XPS, developed by RCPE GmbH, and the multiphase CFD solver of AVL FIRE™, developed by AVL List GmbH. XPS is thus able to predict not only the behavior of several Millions of solid particles, but also their interaction with surrounding fluid flow in arbitrary complex geometries.

The advantages of using the new, coupled software can be summarized as follows:
• Being able to predict and understand fluid-granular flow is necessary for many industries, e.g. process, pharmaceutical, food, plastics, chemical or minerals.
• The coupled software allows faster product and process development, because simulation is faster, safer and, moreover, cheaper than experiments.
• The computational expense for large amounts of particles (up to 100 Mio.) is low, thanks to the GPU-based massive parallel architecture.
• Effective CFD-DEM coupling, with options for user-specified functions and multiple modules on the CFD side.
• In-built GUI for live-viewing and monitoring simulations, capturing images, videos and statistics.

Architecture specifications:
• Optimized to drastically reduce the computational demand per time-step and the memory consumption
• The two codes run on separated computing platforms (CPUs and GPUs): the computing performance of each code is not affected by the other
• Reduced transferred data amount between the DEM and the CFD codes, which depends only on the number of the DEM-cells and not on the number of particles
• Working on deskside environment: workstation with multi-CPU + single/multiple GPU
• Modular software design: highly extend- and configurable

Features and Modules:
• Fully developed Graphical User Interface (GUI)
• Handling of complex geometries (STL)
• Handling of many millions of particles (up to 100 Million on single GPU)
• Poly-disperse particles
• Clumps (Multi-spheres), Tablets
• Heat exchange
• Spray modeling (coating, impregnation)
• Post-Processing tools and support for analyzing simulation results.
• Validated DEM and CFD/DEM coupling (and more on our homepage)

Is it a two-way coupling or a one-way?

[dansu]

We use a two-way coupling between particles and fluid. More details can be found here:
