Transient run and real time
 

HI;

Just 2 retard questions:

1) In the command file (20*1.0E-02) is applied for fixed time stepping, but the run stops (giving out dump files + output file) after 1st time step...anyone know why? (In case: convergence hasn't been achieved)

2) If above is resolved: how is it possible to write out data in USRTRN based on real time (e.g 0.05 s) rather than time steps. Would this be OK;

REALT= (KSTEP*DT)?

IF (REALT .EQ. 0.02) THEN ...

END IF

At present this doesn't seem to be working...

Thanks in advance...

Re: Transient run and real time
 

Your questions: (1) Did you set up the Maximum Number of Iterations under 'program control'? (2) If you use output options:

DUMP FILE OPTIONS

EACH TIME STEP

ALL VARIABLES

END

You should be able to get results for any time step

Hope this helps

Hi Forrest:

Thanks for you response but

(1) Yes, I have set up MAX ITERATIONS. But still no good...only one time step then it stops

(2) I understand what you are saying for the dump file options, but I wanted to write out information from usrtrn at specific time (say 0.1, 0.2, 0.3 secs..etc).

REALT=KTEP*DT

IF (REALT .EQ. 0.02) THEN BLAH... END IF

Any further suggestions...

Thanks again...
