[Gate-users] Simulation difference between Gate9.1 and Gate8.2 -log files attached

Dear Gate Users,

The simulation goes smoothly on vGate8.2 and generates output projections
successfully without any error and warning but the same setup gives
geometry overlap warnings on vGate9.2 and simulation stuck
without generating any output. What may be the problem?

Log files of both are attached.

Thank you for your cooperation.
