Hello,
I try to compute an electrostatic problem, but when my geometry is too big I have the following crash message :

I don't understand this message and the problem work fine when the geometry size is around 1000*1000 (box = 500). Can you help me please ?
I put in attach file the geometry, mesh and problem files and also the python script that I use to launch the simulation.

Cordially
