    Use 2nd order shell elements if you are using OptiStruct

    RADIOSS do not support 8/6-noded shell element.

    Any specific reason for 8 noded shell.

    What type of analysis you are trying at your end?

    Just wanted to improve my simulation results as in many Literature I found they used 8 noded shell elements.

    Instead of working with 8-nodes shell, you can refine your mesh with 4-nodes shell.

    CPU time will be increased, but you have better results (theorically!)
