ACMS solver generate an fatal massage 601 (IFP1D)

Question

Hey,

I used to work with the Lanzos Solver. Now i wrote the Input File with the ACMS solver and include the line:

DOMAINSOLVER ACMS

into the CASE CONTROL, but generate the fatal massage 601 (IFP1D).

I know that ACMS doesn´t work while using SOL 103, but I´m using SOL 111.

What could be the problem to generate this fatal massage?

You need to write it between the SOL and CEND. It should work with SOL 103/111.

Try something like this

SOL 111

DOMAINSOLVER ACMS(VERSION=OLD)

CEND

It needs a seperate license. Please check if you get a license error. Attach last few lines of f06 to identify the error if it fails.
