Hello list,
I have two students working on M*tl*b code where the tetramesh
command is used:
http://www.mathworks.com/access/helpdesk/help/techdoc/ref/tetramesh.html
They would like the code to also run in Octave. On
http://wiki.octave.org/wiki.pl?MissingMatlabFunctions
I have found that tetramesh is currently still missing in Octave.
Is there a workaround/alternative? Can they do the visualization
using another command sequence that would lead to about the same
result?
Thanks!

A possible alternative to process data on a tetrahedral mesh
is to use the function "fpl_vtk_write_field" from the octave-forge
package "fpl" <http://octave.sourceforge.net/fpl>
to export the data to a .vtu file and then use paraview <http://www.paraview.org/
>
to visualize it.
Using functions from "fpl" and "msh" the example from the tetramesh
documentation at the
link above can be reproduced as follows:
msh = msh3m_structured_mesh ([-1 1], [-1 1], [-1 1], 1, 1:6)
f = 1:columns(msh.t);
fpl_vtk_write_field ('test', msh, {}, {f, 'f'}, true);
the resulting .vtu and the visualizatio produced by paraview are
attached.
