    Hi @Varshith_reddy_8

    The message recommends you to define lower values than default for epsu, epsp, epsw.
    https://2024.help.altair.com/2024/hwsolvers/os/topics/solvers/os/nlparm_bulk_r.htm

    Also, use a bigger number than default for NINC.

    You can do that both with your text editor and via HyperMesh too.

    Hope that helps.
