I.e. user can change priority of +applying algorithms on shared subshapes of Mesh shape. +To change submesh priority: +
    +
  1. From the Mesh menu choose the "Change submesh priority" on +selected Mesh item, or invoke from popup menu. + +There are example of submesh order modifications of Mesh created on a Box +shape. The main Mesh object: +
      +
    • 3D Tetrahedron (Netgen) with HypothesisMax Element Volume
      • +
    • 2D Triangle (Mefisto) with HypothesisMax Element Area
      • +
    • 1D Wire discretisation with Number of Segments=20
      • +
    +The first submesh object "Submesh_1" created on "Face_1" +is: +
      +
    • 2D Netgen 1D-2D with Hypothesis Netgen Simple parameters +(Number of Segments = 4)
      • +
    +The second submesh object "Submesh_2" created on "Face_2" +is: +
      +
    • 2D Netgen 1D-2D with Hypothesis Netgen Simple parameters +(Number of Segments = 8)
      • +
    + +And the last third submesh object "Submesh_3" created on "Face_3" +is: +
      +
    • 2D Netgen 1D-2D with Hypothesis Netgen Simple parameters +(Number of Segments = 12)
      • +
    +The submeshes can become concurrent if thir algorithms leads to mesh shared subshape +with different algorithms (or different algorithms parameters, i.e. hypothesises). +In fact, we have three submeshes with concurrent algorithms, becase +they has different hypothesises assigned to them. + +The first mesh computation made with: +\image html mesh_order_123.png +
    "Mesh order SubMesh_1, SubMesh_2, SubMesh_3"
    +\image html mesh_order_123_res.png +
    "Result mesh with order SubMesh_1, SubMesh_2, SubMesh_3 "
    + +The next mesh computation with: +\image html mesh_order_213.png +
    "Mesh order SubMesh_2, SubMesh_1, SubMesh_3"
    +\image html mesh_order_213_res.png +
    "Result mesh with order SubMesh_2, SubMesh_1, SubMesh_3 "
    + +And the last mesh computation with: +\image html mesh_order_321.png +
    "Mesh order SubMesh_3, SubMesh_2, SubMesh_1"
    +\image html mesh_order_321_res.png +
    "Result mesh with order SubMesh_3, SubMesh_2, SubMesh_1 "
    + +As we can see each mesh computation has different number of result +elements and different mesh descretisation on shared edges (edges, +that shared between Face_1, Face_2 and Face_3) + +Additionally, submesh priority (order of algorithms to be applied) can +be modified not only in separate dialog box, but in Preview +also. This helps to preview different mesh results, modifying submesh +order. +\image html mesh_order_preview.png +
    "Preview with submesh priority list box"
    + +If no concurrent submeshes under Mesh object user will see the +following information dialog box +\image html mesh_order_no_concurrent.png +
    "No concurrent submeshes detected"
    +and no mesh order list box appear in Preview dialog box. +
