    Hey /profile/94428-prasannak/?do=hovercard' data-mentionid='94428' href='<___base_url___>/profile/94428-prasannak/' rel=''>@PrasannaK. Thank you for the replay. I came to this topic after reading that pdf itself. The document uses the term 'mesh flow' and 'mesh flow line' but it doesn't  explain what it means. I have read that maintaining  a better mesh flow is required for a good mesh. But what does a better or bad mesh-flow/mesh-flow-line mean?. 

    Ps:Mesh flow doesn't mean the mesh is actually flowing/moving or is dynamic ryt?

    Hi granzer,

     

    This actually only means that the alignment of the connections between the elements is as smooth as possible in relation to the edge geometry.

    Left side has a lot better mesh flow, as the right side mesh.

    This is very important in crash (my field) and non-linear analysis. In general the mesh quality is improved by mesh flow (except number of trias).

     

    Best Regards,

    Mario
