  • When you recognize that your optimization result is growing in an inappropriate way , than your optimization went - something is going wrong

  • The main reason is that the nondesign for this is the tearing off and therefore lost connections of the Nondesign spaces on which the structural loads are applied tear off and lose the connection

    • This results can be seen in iterations where 0 MPa stress stresses occur (see picture below)

  • In the following iterations the model is growing again due to these zero stress

    • If its connect again a connection with the Nondesign space is created anew a stress will appear again
