and even then there are so few ways the really cool morphology can be accurately reproduced that are, again, practical for cost, scale, strength etc. Previous message: Gmsh Do FreeCAD and GMSH work together Next message: Gmsh Do FreeCAD and GMSH work together Messages sorted by: Hi, can FreeCAD save in STEP format If so, this would be better suited for import in gmsh. In reality i think that the practical applications for generative design are pretty minimal, because it's so rare that you're looking to maximize stiffness to weight to such an extreme comprimizing everything from cost to durability. It's not a slick push-button thing like Fusion360, but i have a funny feeling that Fusion's generative design is more an AI-trained model (which lives only on Autodesk's cloud servers) that spits out something that looks FEM-ish rather than doing it the hard (real) way. i think it can even take in tetrahedral meshes (like you'd make with gmsh) from FreeCAD and whittle those down, allowing you to kind of pass a model back and forth to put stronger constraints on the it can generate the FEM-driven design and then import that mesh into FreeCAD for better refinement. there are several FEM solvers which can be used, one free/opensource option called Z88 Aurora looked pretty good. 2: 343 snappyHexMesh snappHexMesh not creating mesh inside the body. 6: 8,068 snappyHexMesh finding problems with emesh file.
considers triplet to be in linear RGB space).I was looking into this a few months ago, didn't go too far with it though.īasically there isn't an "internal" FreeCAD workbench for this specifically. 7: 829 Gmsh Meshing 3D volume from STL/STEP Files (Gmsh) jgross. Peer Reviewed Journal UGC Approved Journal. Quantity_TOC_sRGB has been introduced in OCCT 7.5.0 to help converting RGB triplet to and from sRGB, while Quantity_TOC_RGB passes RGB values as is (e.g. Release notes 0 17 FreeCAD Documentation.

The following code could be used to display color values within 0.255 range in conventional GUI controls: Quantity_Color theColor Gmsh is used by meteorologists for final elements just because it includes the whole pipeline, so you can build geometry mesh, export, and you can visualize some results. So that FreeCAD / GMSH code is expected to be updated to perform RGB/sRGB conversion in place. Gmsh this is an open-source project, so you can use it as you want, and you do not need to pay for it. STEP standard does not clarifies details upon RGB color space, so that OCCT considers values to be stored in sRGB color space to preserve de-facto behavior of most STEP readers/writers (including older versions of OCCT itself) and converts values to linear RGB while defining Quantity_Color. Must be installed in a location that FreeCAD sees to check path FreeCAD uses from a command line terminal.
The thing to remember is that FreeCAD stores it python libraries in a different place than the system version of python.
#Freecad gmsh .17 install#
The main objective of these changes in OCCT is handling of sRGB / linear RGB conversion for proper color reproduction. Gmsh install should be very similar to Windows.
#Freecad gmsh .17 upgrade#
These changes have to be considered at application level while upgrading to new version of OCCT as described in Upgrade Guide. OCCT 7.5.0 introduced changes in treating RGB color space conversion, which affected Quantity_Color class, file Import/Export routines (STEP, IGES, OBJ and others) and 3D Viewer.
