Hello,

I just ran a 1D-RISM analysis with ethylene glycol and I got this kind
of error:

ERROR> RXRISM: reached steps limit Maxstep= 10000
Note: The following floating-point exceptions are signalling:
IEEE_DIVIDE_BY_ZERO IEEE_UNDERFLOW_FLAG IEEE_DENORMAL
STOP 1

My .mdl file is shown below for your reference:

I think I'm having a convergence problem. I don't know which part of my
.mdl file is giving me that kind of error. Can someone help me?
