Hi, congrats for your first post Did you actually add a new equation type to FreeCAD? Heat, flow and so on are all equation types represented as sub-objects of the solver. Those sub-objects can than have all kinds of properties that are required for the equation. In the write.py file you can than access those properties. I wrote a little tutorial on how to add new equation types some time ago: https://www.freecadweb.org/wiki/Add_FEM ... n_Tutorial. The tutorial uses some old module names. They are now lower case - i should probably update that at some point.Chum4k3r wrote: ↑Wed Dec 19, 2018 1:48 pmHello! Regards from Brazil
I'm an acoustical engineering and since my discovering of FreeCAD i've been trying to adapt all my CAD work to the software...
My latest deed was adding the Helmholtz Equation to Elmer solver, but i'm facing some issues with the write.py file, seems like some settings of this equation aren't similar to any other already built in.
How can I add the Frequency I wish to analyse? And how can I add a GUI input to set this analysis step?
Do I need to create a GmshFemMesh by my own within the Analysis object, or the Elmer solver make its own FemMesh?
In case you did add the equation object you just have to add new properties to the equation object. The equation object should be coded in the file Mod/Fem/femsolver/elmer/equations/helmholtz.py or something similar. Look at https://www.freecadweb.org/wiki/Scripted_objects for information about properties of python objects.
If you have any questions please don't hesitate to ask
Well, I'm not familiar with acoustical stuff so I guess just choose which one is more commonly used in that field.
