thank you so much for your reply, but I must say that I haven´t solved the problem.
At the submitting , in the input file analisys, I get the: "The elements have been identified in element set ErrElemMissingSection"
so the resolution does not start. therefore the odb is empty, despite abaqus says that those elements are identified in the element set..
There is no element set created!!!!!
(Or at least i can´t find it neither in the part module, nor in the assembly module, nor in the odb results (that is empty), nor in the display group manager, neither in the internal sets or element sets, etc..)
(PD, what the h.. is tata and tara??? ) = )
