Dear Chris,
My abf code ran for 32480 and then stopped giving a "FATAL ERROR: unknown
floating-point error, errno = 4". I used parallel computing waith 4 nodes
and I have no idea what this error is.Please help me. I paste part of my
log file here and attached the abf script. Thank you very much.
TCL: ABF> Xi at timestep 32480 : 10.7473772938
