Continous output in .op2 file
Continous output in .op2 file
(OP)
Hello people!
I wish for nastran to update the .op2 file for every completed increment so i can check in my postprocessor that the model is not misbehaving, does anyone know of a way to do this?
Kind Regards,
Regretful

set the 9th field on the NLPARM card to "YES". this should do the job.

Its not so easy to find stuff when you dont know where to look!
Edit: I am using "FIXED" time stepping, this is probably not the solution that i am looking for, but i cant be sure until i have tested. Since i had to input the ADAPT keyword to get the INTOUT keyword.
Kind Regards

Take a look at the NLOPRM case control command; there is an option called OUTCTRL=INTERM. If you requests intermediate output on NLSTEP, then for each converged load increment, you get a separate op2 file containing the solution at the end of that increment. These "increment" op2 files are additional to the standard op2 file, and as soon as the increment has converged, the op2 files are sync'd (buffers emptied) and the EOF written. At that point you can read the op2 file (while MSC Nastran is still running), and even move the op2 file elsewhere or delete it.
