Hi All

 

If I get mesh quality error, and even after disabling the mesh quality check I get a fatal error. how is it possible to remesh a meshed part ? does the mesh overwrites ?

 

should I apply the correlating BC and loads again ? what about material and properties?

    Hi,

    If the mesh quality is poor the solver will show the error and you have to remesh / improve the mesh quality.

    From the automesh panel (F12) select elements from the entity selector and select the existing elements which has the poor mesh and perform  remesh of that region. I recommend you to go through Practical Aspects of Finite Element Simulation (A Study Guide) ebook where mesh quality improvement tips are provided (page 242).

    Material and property assigned to the component will remain in the same. But you may have to update the BCs and loads in the elements remeshed.

    When I remesh the meshed solids , sometimes I feel that the previous mesh has not gone away, and it's overlapped with the new one

    Hi,

    To fix the duplicated elements, click duplicates to check the model. Then click “save failed”, go to “delete” option, element-> retrieve-> delete entity.
