  1. @Prakash Pagadala it's quite confidential, i can send you by emal. andrea
  2. i have completed OS-T 1500 and gave me error 4002 as the .out i posted at the beginning. andrea
  3. @Prakash Pagadala It works, thank you do much. Can i ask you an example for NLGEOM? andrea
  4. Hi Prakash Pagadala, how do i do a NLSTAT with LGDISP? many thanks andrea
  5. Hello, I am having some troubles running a non- linear implicit analisys in optistruct, below the .out file.

  6. Hello, I'm running a uniaxial compression test simulation of an alluminium specimen under imposed velocity load. Why RADIOSS does not stop once the yield stress of allumium is reached and abundantly passed?
  7. Good evening to everyone, i'm trying to run a topological optimization but it doesn't work. looking at the .out it shows that a problem occurs in the design variables, the message is: "NO DESIGN MATERIAL OR DESIGN VARIABLES FOUND: ANALYSIS ONLY" after that the code prosecutes with the linear static analysis. The design property related to the desvar is a PSOLID; the analysis regards a mass minimization with a boundary on the maximum stress. many thanks for your help, Andrea
