hello people, I hope you are well.
I wanted to ask you first what is a material point? and then how
  is a local orientation defined at the material point in code aster? How do I define a local coordinate system in aster study?
I hope you can help me
thank you very much

Hello people, I hope you are well!
For a 2D plate I need to make a simple triangular mesh, which is regular. more specifically that two traingular elements form a square (something like in the attached image).
How do I do this from the mesh module?
can you help me?
thank you very much

Hello people, I hope you are well!
I need to know, when I solve a problem through a UMAT, in which element I am and in which iteration of the increment I am. This information can be known? as ?
another question, is it possible to compile a umat on windows? or can it only be on linux?

Thank you so much
Cheers

Hello friends
Do you know if there is any other law of behavior under irradiation for materials used in reactors, in addition to the IRRAD3M law?

Thank you so much
Cheers

Hello dear
How do I do this part ?:
If you aim for less calculation time with OpenMP (meaning without MPI), you should choose ncpus = number_of_cores / 2 (turning off hyperthreading on Intel CPUs also helps). You chose ncpus = 1 ('credit of processes used: 1'). So there might be some time to gain.

Cheers

Hello friends, I hope you are well!
I am analyzing a case of irradiation, using the aster's own IRRAD3M law, and after almost an hour of running, almost 300 iterations I have problems in convergence. Can you help me? attached the message that appeared.
Thank you very very much

Hey guys, how are you?
I try to compile a umat in code aster, through salome shell. I found the impediment that when the main code calls a subroutine (contained in the same main code) it shows me the following error: Procedure 'subroutine name' called with an implicit interface at ...
it is an error that appeared to me frequently. Does anyone know why? Can you help me?

Thank you so much
