What Ansys writes in its *.rst.

What Ansys writes in its *.rst.

Hi all,

I have a curiosity that what data ansys actually writes in its *.rst file?

I do 2 transient analyses of the same problem, the same time steps, the same time duration but different numbers of loadstep. The first analysis is with 2 loadsteps and the second is with 4 ones. I specified the same data output control by OUTRES. However, the result file size of the latter is about 3 times bigger than that of the former. Could any one tell me the reason?

By the way, how to tell ansys to output the reactions at the desired nodes only? The "OUTRES, RSOL, n, Nodal_set" issues an error when I assign with a nodal_set.

Thank you very much.
Regards,
Bridge.

Oops, I found the reason.

The cause of bigger rst file is in my second question. Because I cannot set the output of reactions for the desired nodes, so when I fix all dofs of dead element (by EKILL), the output of these many reactions cause the bigger rst file.

How can I set the output for reactions of only desired nodes?

Thank you.
Bridge.

To answer your last question try the FSUM, RFORCE, or PRNNSOL commands.

I checked all the commands you recommended, however to my understanding,  none of them help to prevent the reactions from output to result file.
