How to assign surfaces to a physical group by colour from a STEP file.
Hi everyone,
I would like to define physical groups based on the colour of a surface that is defined in an imported STEP-file. This would allow me to "colour" the surfaces in the CAD software to specify boundary conditions and then by exporting the "coloured" geometry to a STEP file, it might allow me to easily create different physical groups based on these colours for complex geometries.
When opening a coloured STEP-file in gmsh in the GUI, I can see that the coloured surfaces are indeed visualised correctly in the GUI and therefore indicating that gmsh recognizes the different colours set in the CAD software. However, I don't seem to find a way to be able to create physical groups based on the coloured surfaces. Is there an option to easily assign physical groups by means of the colour properties of a surface in gmsh?
Thanks in advance for your help.
