Hi,

 

I have a bad quality hex elements and want to fix this (Jacobian >0.3).

I have tried to move nodes manually but it is hard to recognize which nodes need to move because elements flattened and penetrated.

Is there has an option that can fix these elements automatically with some parameters? (e.g. greater than Jacobian 0.3 etc.).

Thank you.

    That's solid mesh? Share model?

    Yes, it is solid hex mesh distorted after the Human Body Model changed it position.

    Hi,

    You can prefer using 2nd order Tet mesh mapped with existing Hex mesh where quality hex is difficult to obtain.

    Hi WPak

     

    May be you can try using a finer mesh size along that region, so that you can modify manually.

     

    Thanks
