I am trying to do a segmented potential energy scan around a dihedral for a molecule. I have optimized the geometry to a minima, and the scan runs from [-180, 180] in steps of two points at a time. This is the input file that I used to calculate the energies at $\phi = 170$ and $\phi = 160$. The ...

I'm trying to create a training model for neurosurgery that utilizes 3D printed bones and associated vessels. I intend to use a pump to run artifical blood through these vessels. So they need to be elastic and should be possibly damaged/cut by the wrong cutting maneuvers or drill touches. Ideally...
