我在Siwave在使用Simulation中的compute resonant mode时出现的问题:
Simulation Status
Simulation "Resonant Mode Sim 1" started on host PCASUS at Sat Jun 11 20:34:26 2016
Simulation "Resonant Mode Sim 1" terminated on host PCASUS at Sat Jun 11 20:34:26 2016 with exit code 1
Pre-setup Validation Error
SIwave analysis mandates that at least one plane be present in the geometry
请问大家是怎么解决的,急需!!!
