The conversion utility of Ansys Polydata does not modify the HYPERMESH element or node numbering. Since element and node numbering for Ansys Polyflow must start at one and must be continuous, ensure to number the elements and nodes in this way in HYPERMESH.
Ansys Polydata will detect and report some numbering errors during the conversion, but the other errors will only be detected by Ansys Polyflow. Verify that the number of elements and nodes reported after the conversion by Ansys Polydata is identical to the number of elements and nodes reported in the TOPO section of the Ansys Polyflow listing file (described in Contents of a Sample Listing File).
Note: Ensure that the number of Ele and
Vert reported by Ansys Polydata after the conversion
matches the number of bricks and nodes reported for the root mesh in the
TOPO section.
By default, Ansys Polyflow will optimize the element numbering, which affects
the CPU time required for the calculation, before it begins the calculation. If
you prefer to perform the optimization yourself in HYPERMESH, and have
Ansys Polyflow use that optimization instead of optimizing the mesh itself, then
start Ansys Polyflow with the -opt msh command line
option, as described in Using Optimized or Decomposed Mesh. If you perform the optimization in HYPERMESH (if
any), use a method of element renumbering that minimizes average wavefront to
reduce the CPU time of your simulation, and that minimizes the maximum wavefront
to reduce the memory requirements.
