Default starting with dump file

I am having trouble strating a run from a dump file. I have the error:
:>MODEL BOUNDARY CONDITIONS ERROR OPENING RESTART FILE ON UNIT NUMBER 16 THE CFX-4 SOLVER HAS BEEN STOPPED BY SUBROUTINE OPENIO

Anyone got any hints? Also, how does the solver "look" for the correct dump file (does it need an appropriate name, and if not how are files prioritised)?

Lastly if I want to set initial variables and read in variables from the dump file, will these conflict?

Many thanks in advance

In case anyone else out there gets this error. It was caused by the solver not "finding" the dump file, no matter what I named it. You can point the solver to the dump file on the command line using -r e.g. runsolve4 -c m01.f -f aaa.f bbb.f -r dump_file.dmp

Does anyone know where references to command line instruction can be found?

Thanks

Hi

Been a while since is used CFX-4.4 but i think you need to make sure the .fc and .dmp restart files have the same number.

Another thing, whats the point restarting from a dump file and also specifing intial field variables? The restart data will just be over written! This is just like starting a fresh run.

Regard James

I am using the dump file as the initial condition for most variables (u, tke, e etc..), but have scalars added in the second run.

Many thanks

For command line parameters use "runsolve4 -h".

You can also look in the top of your .fo file when running from the environment to see what command line command was used to create the run.

Your SET INITIAL GUESS values will overwrite anything that's read in from the dump file. Useful for re-initializing a scalar field but not the flow solution.
