lzgwhy is on a distinguished road
Recently, I am doing calculation about fluid-structure interaction using Fluent with its UDF. However, I found the method of updating mesh is very important for the calculation. In order to use the method of updating mesh in Fluent, I must use the tetrahedral grids, even the inconsistent mesh technique, which may reduce the accuracy. I read some literatures, but I found their methods are very difficult or not suitable for UDF
of Fluent. So I wonder some techniques about updating mesh in dynamic mesh technique when the structured mesh or hexahedral mesh is used. Could anyone give some suggestion or some literatures? Thanks in advance.
