Hello,

First of all, thank you for answering. Sorry for my generic question, Code Aster is something new for me.

I am uploading my .comm file, I will be very pleased if you could take a look and tell me where could my error be. My geometry is a simple box, with a good mesh, and I am blocking a face and trying to apply a weight force all over the solid. I don't really obtain an error from Code Aster, but the time step gets smaller and smaller, the simulation becomes eternal and doesn't converge. The weight I am using tries to be "soft" applied and it's not realistic at all, that's because I think something is wrong. This way I could not simulate any real problem!

Thanks in advance.
