This article simulates the vortex-induced oscillations of a rigid circular cylinder with elastic support using the new ANSYS CFX rigid body solver. This solver requires no solid mesh to setup FSI(Fluid Structure Interaction)simulation. The two-way case was setup in CFX only. Specific mass of ...

Thanks in advance. May 19, 2022 at 2:30 am vinnakbm Subscriber Hello, In CFX rigid body solution, is it possible to couple motion of 2 rigid bodies so that they don't intersect (unrealistic as one body cannot penetrate the other during the motion)? Thank you!
Last thing may you remembered, I’m still continue in to the steady state rigid body free surface flow with 16.2 version. But the other non rigid body analysis are continuing with 21 version. I haven’t solved the movement problem of the meshes after the 16.2 version of Ansys’s. For fr...
