How to get the same post results as the example case shown in turtleFSI

Dear @keiyamamo
I tried your suggestions and it works well. Thank you!
And as for the separation, I will try later.

Hi @zhangmuElias
You need to apply 'warp by vector' filter from Paraview to 'deformation.xdmf' to see the mesh deformation.

Thanks for your reply!
I added this filter to deformation.xdmf, and it can show the mesh deformation.

So I guess I can't show the deformation just using the velocity.xdmf but need the velocity.xdmf and deformation.xdmf together? And also is there a way to separate the mesh of solid part and fluid part? In this contour, the two domains are still mixed together.

No, you can't see the deformation from the velocity only. You can use 'Append attributes' in Paraivew to combine velocity and deformation and visualize velocity while mesh is deformed based on the 'deformation.xdmf'.

There's a way to separate fluid and solid domain, but you would have to use FEniCS function and save the mesh based on the domain id given to each fluid and solid.
