Re: [AMBER] Segmentation Fault

Hard to tell, but I strongly recommend visualizing the system in vmd or
something similar, and look around.

Indeed, the bond energy is huge, but I am more worried about the vdw and
eelec energies, which point to some overlap between atoms.

I have a total of 465,133 atoms in my system which is on the higher end of simulations most of it the solvent at this point. I did a little research in the AMBER archive to search for a solution and did come across checking my file for bad connections because my bond energy is high, but when I do the checkValidity in parmed it tells me the inpcrd file is OK.

In all honesty, I'm not sure what is vital for the control aspects of the minimization file and looking at the Amber16 reference manual (the version I'm working on) I have included almost all the minimization qualities listed and some other aspects that I thought would help the situation. I know that I'm trying to create a periodic (PME?) minimization file.
