  1. thanks for your reply, the only other warning/error I'm getting is this: *** WARNING 1932: PROD ID 11 is not referenced. Any ideas? On another note, going back to the free sizing phase - the optimisation doesnt do anything if my laminate has plies any thinner than 2mm thickness resulting in a much heavier chassis than the one I'm trying to optimise even after free sizing. IS there away round this? Thanks
  2. Hi, I am currently trying to do composite optimisation of a carbon fibre sandwich structure monocoque. I have been following the "composite optimisation of a formula student monocoque" tutorial on the Altair university training website and am up to the shuffling stage however am not getting any results and getting this message: *** WARNING # 1569 for element id = -70001. Thickness is zero for this composite. This will produce meaningless stress results and may cause singularity of the global stiffness matrix. *** WARNING # 1569 for element id = -70002.
