Looks like you are passing a tet mesh conn list to mesh_issolid. Tet meshes
are always solid. Plus, the tet mesh conn lists are a different format than
the polygon conn lists.
You should be using the variable c, not tc.

You can if you do:

ISOSURFACE, vol, isovalue, v, c
print, MESH_ISSOLID(c)

Do you mean isovalue?

It depends on the range of values in the volume and what values you want the
surface to represent.
