[Gate-users] Simulation stuck at geometry initialization

[Khalid Hussain]

Dear Gate users,

I checked geometry from each x,y and z directions and it seems to be fine
but still simulation stuck without any error at *Initialization of
geometry *
[image: image.png]

The macro files are also attached
Your kind cooperation is highly appreciated
