DId not completely understood all you told me, but I reached to make it work with this command in cmd: ccx_dynamic prueba\Analysis-42_gears_Aurea
I runned this inside the location of the calculix solver and put my inputs in a folder named “prueba” to test.
It worked, so I will work this way! I prefer not to change path or variables in the computer.
To determine the number of CPUs, I read you have to write this in cmd, but not sure I make it work properly.
Should I run it in the same way??
