New ESI water simulation module enables predictive crash simulation

0

Thanks to its new water flow module, the ESI Group’s Virtual Performance Solution enables predictive crash simulation by accounting for fluid mass and momentum influence during a crash event. This breakthrough technology can also be used on hybrid and electric vehicles.

This new module enables engineers to predict fluid structure interaction (FSI) accurately with minimal effort. It is designed to represent extreme situations involving fluids, such as water leakage, water jet pressure or tank sloshing. This is especially critical in a crash situation where the mass coupling and incompressible behavior of the fuel can significantly change the accuracy of the crash simulation result.

Startup company EP Tender reported on how the new water flow simulation module was instrumental in helping it guarantee the safety of its new trail-mounted electrical battery units for electric vehicles.

“Using Virtual Performance Solution has enabled us to virtually validate our crash scenario for the generator’s fuel tank and to demonstrate that our trailer brings more energy absorption capacity,” said Jean-Baptiste Segard, founder and CEO of EP Tender.

“Integrating ESI’s latest water flow module for tank sloshing in our model has been particularly efficient to accurately model the content of the tank and get more realistic results.”
