Hi Mike,
You need to either generate the mesh using the simple mesh generators that are
in the sfepy package (just block or cylinder meshes), or (most often) you need
to provide a mesh file, created in advance in an external tool. Many
open-source or commercial softwares can be used for meshing. The following
formats are supported thanks to meshio package:
$ python3 script/convert_mesh.py -l a b
sfepy: Supported readable mesh formats:
sfepy: --------------------------------
sfepy: abaqus (.inp)
sfepy: ansys (.cdb)
sfepy: comsol (.txt)
sfepy: exodus (['.ex2', '.e', '.exo'])
sfepy: gambit (.neu)
sfepy: gmsh (.msh)
sfepy: gmsh-dg (.msh)
sfepy: gmsh2-ascii (.msh)
sfepy: gmsh2-binary (.msh)
sfepy: gmsh4-ascii (.msh)
sfepy: gmsh4-binary (.msh)
sfepy: hdf5 (.h5)
sfepy: hdf5-xdmf (.h5x)
sfepy: hmascii (.hmascii)
sfepy: med (.med)
sfepy: medit (['.mesh', '.meshb'])
sfepy: mesh3d (.mesh3d)
sfepy: nastran (['.nas', '.fem', '.bdf'])
sfepy: tetgen (['.node', '.ele'])
sfepy: vtk (.vtk)
sfepy: vtk-ascii (.vtk)
sfepy: vtk-binary (.vtk)

OK, so is fish_heart.py in your working directory? And how did you install
sfepy (which version)?
Anyway, maybe start with the example [1], which is up-to-date and simpler.

Can you post how you run the example module?
If it is the file from [1], note that it is already 10 years old, so it likely
needs updating for current sfepy.

Hello !
Is there a way to export data as a audio sound-file ? At least the kind that could Work ?
For instance, acoustics3d.py or vibro_acoustic3d.py could export vtk file that could then be converted into a wav or aiff one ?
Is there any example somewhere ?
Thanks !!
O.
