High performance computing (HPC)
Supercomputers for intensive computing
The CEVAA relies on the CRIANN, computing mesocentre for Normandy, to have access to supercomputers.
Here are some examples of studies carried out by our simulation team on CRIANN’s MYRIA supercomputer:
- Vibro-acoustic calculation with parallel CODE_ASTER for a model with more than 3 million degrees of freedom
- Rapid dynamic impact calculation with RADIOSS
- Metallic AM powder bed spreadability calculation (using discrete element code LMGC90)
- Numerical Experimental Plan (DOE) for calculating the impact noise performance of a multilayer floor covering
Example of calculation time savings for a simulation of the impact sound of a multi-layered floor:
|CODE_ASTER version||Calculation of the first 50 modes||Calculation of the acoustic response|
|Sequential (single-core, 50 GB RAM)||35 min||30 hours|
|Parallel (26 cores, 50 GB RAM)||8 min||2 hours|
