I mainly want to use SalomeMeca geometry toolbox for partitioning my parts. I have my basic geometry, generate some planes and do the partitiones. In SalomeMeca the partition is mentioned as solid. Even when I do a cut plane everything looks fine.
As soon as I import the exported partition as .step it always results in shell bodies (not solid as shell mentioned in the forum already). Therefore I cannot use transfinite mesh algorithm. Someone has experience in importing modified SalomeMeca geometries in PrePoMax?
Thank you Gunnar with .brep the sliced part is exported as pure solids. On the other hand I can only export one single solid or one compound at a time. Is this a normal behaviour? Never worked with .brep so far.
Yes, that’s how it is. If you have several solids and only want to create one file, you need to build a compound before (the same applies if you have several compounds or mix single solids and compounds). But I don’t see any difference to the step format here.
Brep can also be used to export single surfaces, but has the disadvantage that when you create a surface compound in prepomax, it doesn’t contain any geometry (the compound is invisible and cannot be used any further; the same applies when using Iges files). Even if the compound was previously created in Salome, only the individual surfaces appear in prepomax. But fortunately in this case it works with step files.
is there any purpose since Salome capable to do meshing of structured hexahedral element when partition is already done? PrePoMax can import Unv mesh format generated in further.
I have a mixed feeling with this so far as I entcountered some problems. See my following thread:
But yeah you are absolute right that Salome has a strong mesher itself and can do all the stuff you want. On the other hand you need to import all the additional informations that you can use the graphical selection method in PPM e.g. surfaces for BCs. This could be a little bit messy in bigger models with many contact surfaces and so on.
indeed, many opensource project collide in feature, thus make user bit confused. An example is SolveSpace in parametric models, later FreeCAD and Salome. I use CADbuilder, a purely CAD oriented from code base of Salome, unfortunately these softwares is not opensource as derivative.
regarding merge node feature of my comment is available then, but connect by equation is not yet. Also, mesh based selection for defining boundary condition and contact in PrePoMax is good enough compared to CAD geometry base except in patch.
