FEATool Multiphysics v1.14 Released, Features Parallel Processing Support for FEA, CFD, Multiphysics Simulations

KOWLOON, Hong Kong, May 25, 2021 – Precise Simulation Ltd. is pleased to announce that, the FEATool Multiphysics version 1.14 and corresponding CFDTool 1.7, toolboxes are now available featuring built-in parallel processing support for the FEniCS FEA, and OpenFOAM and SU2 CFD solvers.

Parallel Processing Support

Full support for solving fully coupled multiphysics and computational fluid dynamics (CFD) models with MPI solver parallelization in OpenFOAMFEniCS, and SU2, is now available with both FEATool Multiphysics and CFDTool. Parallel processing for physics and CAE simulations effectively means that models are split and subdivided into parts, which then are solved in parallel on the available CPU cores, after which the results are recombined. By splitting and distributing the work both larger and more complex simulation models can solved significantly faster.

As usual with FEATool and CFDTool, the complexities of setting up parallel simulations is now essentially completely automated. The only new change is that you can select the number of parallel processes to use (typically taken as the number of available CPU cores). The toolbox automatically subdivides the meshes, defines and sets up parallel case files, solves, and recombines the solutions completely seamlessly so that users can get the benefits of parallelization without even having to think about it.

Multi-Solver Simulation

The unique Multi-Simulation feature of FEATool Multiphysics allows users to easily set up and run physics simulations with any one of the OpenFOAMFEniCSSU2, and built-in multiphysics solvers, all from fully integrated GUI and CLI interfaces.




It is now also possible to select and solve for different equations and physics models with different solvers. This enables one to use the most accurate and efficient solvers for different parts of a model. A new tutorial example of modeling cooling via forced convection in a tube and fin heat exchanger demonstrating this is now available. In this multi-simulation model the flow field is solved with the OpenFOAM CFD solver, after which the temperature field is solved with the built-in multiphysics solver (using the flow field computed with OpenFOAM). Combined with the introduced parallel processing support, the multi-simulation process saves both computational time and memory, and enables solving larger scale models not before possible with limited resources.
