Hi,I would like to ask is there any way to prepare the input file for fastImp?
I have noticed that E.M.Workbench could prepare the input file for fasthenry.But I didn't find any open source do this for fastImp.The only way I know is hand-write .inp file,but this is far too difficult for complex graphics.

Hi Epi,
you are right, there is no support so far in the E.M.Workbench for FastImp input files. As far as I know, there is no open source software directly able to do that. As you may know, FastImp was designed to accept PATRAN-like input files, but PATRAN is not open nor so widespread as other software (actually it is a bit specialistic).
Also, you are also right about preparing the input file manually; it is complex, unless your requirement falls into one of the cases that is already supported by the basic geometries in FastImp (circular spirals, etc). The generic PATRAN input file requires a topological description, i.e. the triangular or quadrilateral panels are defined on a set of common vertexes, you may not duplicate the vertexes (so you actually know which panels are connected with which other panels thanks to the vertexes they share); plus the boundary panels (B) MUST be quadrilateral; this complicates the matter.
Now your best option here is create a script to generate the geometry and/or modify directly FastImp extending the number of geometries it can internally generate. The other option is writing some script in FreeCAD to export the geometry in PATRAN-like format, but in this case you cannot naively export the vertex locations because as said you cannot duplicate the vertexed - you must export the geometry having a certain topology.
If you are interested, we may propose an extension of the E.M.Workbench to support FastImp; for that we'd require a bit of sponsorship, if you can support us.
Thank you
Enrico
