[ICEM] I cannot split a surface

gaza · July 11, 2016, 09:35

Hi all,
I drew a model in catia and saved as a stp file.
Model (a parallelepiped) has dimensions 1x1.5x1 m. One of the faces
has to be split by a thin strip of thickness 4 mm. I drew this split
eaysilly in catia but when I import the stp model to ICEM there is no the thin
split. Other geometry is created but the strip does not. Does anyone know
how to fix it? I tried tolerances in settings but with no success.

Maybe try saving it as a different file type, like CATIA V4 or parasolid, and then loading it in to ICEM. I just know that .stp files give me a lot of problems in ICEM.

You can try to split in Icem. You create the poins, edges, then you have a function to split surface by edges. Why don't you try that ?

Hi diamondx,
Of course I did it. But it seems that ICEM does not see so small elements.
After split the surface is still unsplit.
I think that this issue can be the result of tolerances but I cannot find where it is.
Any ideas?
