. I am running a FLOTRAN VOF problem and am getting the following error message. What should I do?
*** ERROR *** CP= 97.109 TIME= 09:59:42
The time increment at substep 1 for VOF advection is too small, stop.
Increment = 1.953125E-03.
The FLOTRAN time step is much too big. The VOF algorithm divides it as necessary, but stops when it has divided it too many times, because the VOF and flow solutions are too much out of date.
Also, problems with surface tension need smaller time steps.
