FSI in Simcenter STAR-CCM+

How to set up a FSI simulation in Simcenter STAR-CCM+

This week we will take a closer look at the settings for using fluid-structure interaction (FSI) in Simcenter STAR-CCM+. This blog post is inspired by the tutorial Diaphragm valve, found in the documentation for the latest release of Simcenter STAR-CCM+, 2021.2 (you find the tutorial under Solid stress).  FSI is when you have a two-way coupled interactions between a solid domain and a fluid domain. For example, the solid can be flexible and moving in a fluid. Then the resistance of the fluid will deform the solid. Since …
