High Performance Computing (HPC)

In order to deal with large-scale cases by numerical simulation, the use of High Performance Computing (HPC) is essential in order to obtain calculation times compatible with the deadlines for returning results to customers.

The 6NAPSE Group relies on CRIANN, the 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
• Metal additive manufacturing 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:
