Re: Base Track modelled with DKT

Hello Humberto,
I think you confused the meaning of MAILLE (= ELEMENT) and MAILLAGE (=MESH).
Best regards,
Richard

Thanks Richard!!!, That was my problem and it works now., also at the end I changed the stress calculated from the nodes to Gauss points, it seems to be working perfectly. If anybody is interested in the files please PM me.
