[ICEM] ICEM does not show the Premesh

mohammad · December 30, 2020, 00:13

Hello Experts and happy new year

I am meshing a series of airfoils with some small differences. I have imported a new geometry (parasolid: *.xt) into an existing ICEM file ( and replaced the geometry with the existing one).

Then I did all the associations again. The edges are fine and associations are correct and there is no error. However, I cannot see PREMESH. (NOTE THAT THE PREMESH EXISTS, SINCE I CAN CONVERT IT TO AN UNSTRUCTURED MESH, BUT THE SOFTWARE DOES NOT SHOW IT).

Does anyone know how to display the PREMESH (in 2019-R3)?

Best regards,

Hello,

Is the box beside the Pre-Mesh in the Blocking tree checked off?

I have checked it..it was already ticked...
The solution was to associate faces as well.

Thanks for your help in responding.
