Starting from v2.0.2, I am just impressed how good structural meshing now works with the new Mesh Refinement for compounds. I would like to share some positive observations, using a bolt-model as example:
The CAD model is created with the shaper-modul inside salome. All volume partititions are already done here, so that the compound consists of 116 six-sided parts. For some reason this specific model must be imported as brep file to get a compound with solid-parts in prepomax, importing it as step file i only get shell surfaces.
If you want to learn more, please visit our website.
The next observation is, for a structural hexa mesh the value for the Min element size can be higher than the later used value for a refinement. So this is only necessary for creating refinements for tetra meshes.
Using mehing_parameters with a huge value for Min and Max + Transfine_mesh (Recombine = Yes) creates a hexa mesh with one element per volume.
Next i use mesh_refinement for the shown 4 edges (alternativ the 4 faces could be selected). The detection of finding all opposite edges, where this refinement has to be projected to, works very good so that it is not necessary to select all opposite edges as well.
Plus, the whole thing works the other way around too: Starting with a fine mesh and then using mesh_refinement to coarse selected regions:
In the next step you can then create two element-sets for the upper and lower sections and convert them to parts to have the needed cutting-plane where pre-tension can be applied to (the remaining part is then empty and can be deleted), unfortunately this leads to losing the associativity to the geometry based mesh creation. On the other hand, when having a model with many bolts, it makes more sense for me to mesh one bolt and use the transform option to copy it several times to minimize the meshing effort, in this case the associativity also gets lost.
By creating the element-sets, in some cases the &#;Geometry based selection&#; works not always proper, means that sometimes some inner elements will not be recognized. Here i suggest to use the &#;FE mesh based selection > Element&#; instead:
The only option I would like to have is, to be able to specify the number of elements or nodes per edge as an alternative to the element size. Anyway, I&#;m thrilled.

MESH TYPE
Choose from a wide variety of Square, Rectangular, Round mesh holes and Weaving, Welding, Punching types.
MESH SIZE
In addition to selecting an opening size, many Wire Mesh items also have a mesh size which is determined by measuring the number of openings per lineal inch from the center of one wire to the center of an adjacent wire. If perforating or expanding metal, please advise the holes size and shapes.
OPENING SIZE
Select the opening size of the Wire Mesh. Opening size is the clear space between wires and is measured from the inside of one wire to the inside of an adjacent wire. For rectangular opening items, a width and length opening measurement is required.
WIRE DIAMETER / WIRE GAUGE
Choose the Wire Mesh diameter thickness (in inches) or wire gauge. We provide more information on wire diameter and wire gauge equivalents in the link provided in the Charts section on the Wire Mesh resources landing page.
PERCENT OPEN AREA
Identify the percentage of open area desired in the Wire Mesh or Perforated Metal.
Select the opening size of the Wire Mesh. Opening size is the clear space between wires and is measured from the inside of one wire to the inside of an adjacent wire. For rectangular opening items, a width and length opening measurement is required.
SURFACE FINISHING/ TREATMENT
Select the primary material type including Aluminum, Bronze, Carbon Steel, Copper, Galvanized Steel or Stainless Steel, taking into consideration climate or environmental realities. Inventory is typically &#;mill finish&#; unless otherwise specified. Some items in inventory have a vinyl coating or can be powder coated. We provide more information on Primary Material Types and Product Finishes in the links provided in the Overview section on the Wire Mesh Resources landing page.
PRODUCT SIZE, FORM & QUANTITY
Determine the number of sheets and/or coils including cut-to-size pieces and stub preferences if applicable.
ACCESSORIES
Determine if Wire Mesh Accessories such as Angle, Flat Bar, or U-Edging framing solutions are required for your application.
APPLICATION
Product applications/uses include screens, partitions, facades on parking garages and buildings, cabinet inserts, enclosures, and more. We invite you to browse Wire Mesh applications in our Gallery.
