subprocess "%3" died unexpectedly !!

Dear all,

While simulating an antenna with HFSS, i get this error message and the simulation stops:

Seeding mesh, process mesh3d: subprocess "%3" died unexpectedly

does anybody knows what causes this problem and how it must be solved?

thanks in advance

Maybe you have a very small object in your structure. The aspect ration between the smallest and largest objects should not exceed 1e6 I guess.
