This is very much possible, but it is a bit tricky. The idea is that you
create a defibrillator source that intersects the torso surface. if you have
a paddle geometry (a cube will do to start), you situated it with the
EditMeshBoundingBox model so that it intersects the torso (better to be deep
than shallow). You then use the ClipFieldByMesh module to just get the
intersect of the torso and the paddle. use GetFieldBoundary to get the
boundary of the torso. find the distance map to the torso boundary in the
intersect volume (GetDistanceToField) the clip that field by the distance
that you want (2-5 mm) using ClipVolumeByIsovalue. This is then one of your
sources in the model. It is not really on the surface but a little into it,
and this method hasn't been as thoroughly vetted, but it should serve as a
starting point. If you need more explanation feel free to ask.
cheers,
Jess
