Use “ExtractSurface” filter, then use File → SaveData

Hi @Maryam_Mgh !

@Maryam_Mgh

how can I extrude this surface?

If you want generate a 3D surface or 3D volume from a 2D shape, you may try “Linear Extrusion” filter or “Linear Cell Extrusion” in ParaView.

Hope this helps.

Hi, Thank you so much. I did that but there is no change after extrusion.

Perhaps you need to adjust the scale factor. Or perhaps the direction vector of extrusion.

It would help if you would share your data. It’s hard to guess what your problem is without seeing anything.
