Hello!

I am new about FSI simulation.

I simulate a periodic domain of the pump's rotor and stator from a 3D CAD file.

The procedure is...

3D cad file -> create periodic and fluid domain -> import ansys geometry -> export to turbogrid(to create mesh) -> setup CFX-Pre -> RESULT

Is it possible to do the FSI simulation by this cfx result?

or I need to import origin cad file into ansys to do the FSI?

Thnak you~

Hi,


it depends if you are talking about 1way or 2way FSI.

1way: just export the results (e.g. pressure) from CFX and apply on the pump structure.
2way: import CAD file into CFX Pre, define FSI and you can initialize the results from your previous analysis. 2way FSI is a very complex analysis, you may encounter many issues and the result may not worth it.

Thank you so much!

I found some tutorial videos on Youtube about 1way of FSI.

It seems that 1way is easier than 2way!

Thanks for your reply!

1 way is much more easier, in 2 way FSI you would come across many difficulties. SInce you do not have years of experience in CFX I would not recommend 2 way FSI. Go for 1 way.
