    I am getting a message as 'problem with the surface normal orientation, please check'.

    Hi Mayur,

     

    Maybe adjusting surface normals will help...

     

    Goto Tool page>> Normals>>Surf and adjust normal directions for surfaces.

    Hi sir, 

    I tried all the above suggestions, and after running for 5-6 hours, it is again showing the same error. 

    Can you please check the file and see what has gone wrong in it?

    Hi Mayur,

     

     

    Do you have solid elements in your model and are you using solid element set for ERP output?
