Hello Everyone!
I want to simulate a rigid sphere inside flowing fluid. Physical Specifications followed:
1. This rigid sphere DO NOT DEFORM
2. The rigid sphere and fluid is fully coupled
2.1 fluid loading on the rigid sphere in order to make it move inside fluid
2.2 the velocity is transmitted to the fluid on the surface of rigid sphere
3. As the rigid sphere moves the mesh also moves
Which models should I adopt? I have tried
1. CFD model + Structure Model + ALE + FSI Fixed Geometry combinations. (Do not work as rigid domain is not accepted by solvers)
2. FSI model (The solid deforms, Not Acceptable)
Is there a method in COMSOL to simulate that? I am open to any advices, Thanks in advance!
Sincerely
Xiaoqiu HE
