I am trying to solve a FEM Model by using solution type:"SEMODES 103".With in 1 minute i can able to see "Job finished" in the solution monitor.Solving operation is not performed by NX-Nastran so thati am unable to see the result. I have opened the *.F06 file to check for the problem.I have found that"TOTAL NUMBER OF TIMES TOLERANCES WERE EXCEEDED". I have removed the threshold value parameters such as Aspect Ratio,Jacobian Ratio, Jacobian Zero etc in the quality check criteria.Still i am facing the same type of problem while solving. I have run the FEM model successfully in other softwares such as NX-IDEAS and ABACUS.i have uploaded the error file for your reference.
Thank you very much in advance.
