Remeshing method

    • Alberto


      Can someone explains the difference between the method-based remeshing algorithm and the unified one ? I can't find anything also in the Fluent's documentation. My problem involves both  rotational and translational motion of 3D object with non symmetric shape and i'm facing several problem such negative volumes or crash of the simulation, so i would optimize all features.

      Thanks in advance

      You can find some information in the user Guide here: 46.9. Dynamic Mesh Task Page (ansys.com)

      Basically, the Unified Remeshing method (default) should work well on triangular/tetrahedral cells, while the Methods-based method should be applied for other cell types.

      Negative volume cells can also occur if your time step is too large relative to the moving zones.
