Hey Stathis,
Okay, some more feedback for you.
Definitely getting a better shape for the brachiocephalicus.
Not seeing a meaningful change to the brachioradialis yet.
The volumes on the back leg still feel like they could be deforming better -- the whole muscle mass moves as one, rather than getting any individual play between muscles (sliding on each other, separating a little, etc)
Your muscle density is still pretty light at 306. Default is 1060.
Don't forget there is also the inertial damping attribute on the zTissue node that can negate some of the world space inertia going through your muscles, if you find they've got too much secondary motion.
I think you could double or even triple your pos sensitivity to 2 or 3, just to amplify the effect. See how you go.
As for the fascia pressure at 0.92 and pressure between 40 and 80 seemed to work for me. If the fascia is exploding it's usually because there are self intersections on the objects it's colliding with. This will cause our collision mechanism to do the wrong thing because the point-in-volume test won't properly against objects that have self-intersections.
You can run this loop on any frame to see if you have self-intersections:
# select any number of meshes
import maya.mel as mm
import maya.cmds as mc
for mesh_name in mc.ls( sl=True ):
mc.select( mesh_name, r=True )
mm.eval( 'zFindSelfIntersections' )
if len( mc.ls(sl=True, fl=True) ) > 0:
break
print 'self intersection(s) found'
