In the demanding world of Finite Element Analysis (FEA), performance is king. When tackling complex engineering problems, especially with large datasets and intricate geometries, how efficiently your software scales with increasing computational resources can make or break your analysis time. This is precisely what we set out to investigate: a Read more
The world of Computational Fluid Dynamics (CFD) is constantly pushing the limits of technology, and at its heart lies High-Performance Computing (HPC). To truly innovate and solve complex engineering problems, we need robust, efficient, and scalable computing infrastructure. That’s why the HPC Challenge at the OpenFOAM Workshop 2025 in Vienna was such Read more
For engineers and researchers relying on explicit dynamic finite element analysis, OpenRADIOSS is a powerful and increasingly popular open-source software choice. But how well does such complex software scale in a High-Performance Computing (HPC) environment, especially when leveraging the elasticity of the cloud? We dive into recent tests conducted on Read more
A new benchmark to evaluate performance of two of the most common FEM/FEA solvers is proposed. On the cloudHPC platform it is possible to execute both calculiX and code_aster simulations with the most advanced MPI compilation. None of the two solvers is, in fact, available in multi-core use – also Read more
ERROR: FDS MPI_PROCESS In the past we highlight how you can set your FDS analysis correctly to reach a good scalability. Often this involves using the MPI_PROCESS parameter to correctly split the workload among different processors. When doing that it may happen that you rin into the following error: The Read more
To speed up complex fire simulations in FDS it’s important to achieve a good scalability and equilibrate the hardware resources. Fire simulations commonly leads to long calculation time due to the large number of physical and chemical processes involved. In complex fire simulation the available hardware carries out a high Read more
