    Hi @anderlanza

     

    this error is because law 28 honeycomb material is assigned to 2D elements, which is incompatible (see attached document).

    Hi Ivan,

    First of all, thank you for the respond .

    In the image below I was putting  the honeycomb material in 'espuma' and ' honey' and it was a BRICK, in which way I can change number of nodes?

    As I have seen in the pdf that you have send me, if you have  BRICK the only way to have compatibility is by having 8 nodes so what can i do?

    The problem is you have SHELL3N (triangle 2D elements) in component which were assigned law 28 material.

    Isolate the components assigned to  law 28 material and mask solid elements, then delete the shell elements.

    Maybe there was no animation output frequency (ANIM/DT) defined.

    Just find the folder with model files and open run_name.h3d file.
