Hi, hope I'm in the right sub forum.
Am currently in progress of modelling a wind instrument in OpenSCAD (or if this doesn't work FreeCAD, MoI or Blender).
In order to reduce the amount of prototype iterations it would be great if I could blow virtual air into the thing and compute which tone would get out. It is a fipple based design, so lip tension wouldn't be a factor.
Is that possible? And if yes, is that possible with the FreeCAD CFD workbench?
And if it is indeed possible - would I need my instrument be modelled with surfaces (NURBS/SubD) or would a high res STL with tesselated roundings (as I e.g. could get it out of OpenSCAD) be sufficient?

Re: Audio calculation for wind instruments
Hi, sorry for late reply.
At the moment, the solvers below are supported by the cfdof-workbench.
Hisa is a compressible solver, but the use is intended for high speed aerodynamics.
But maybe...

I have no clue about computational accoustics, please see thesis from Ryan Flamm,
he uses the rhoPimpleFoam solver. Maybe that helps.

Maybe elmer can do the job

Thanks for the directions! Will have a look.
