Output frequency

[Katrin]

Hi,

I am running some time-history analyses. The analysis comprises many time-steps because I am trying to predict a quasi-static test, which takes very long. I was wondering whether it is possible to output only for example every tenth time step instead of every single one? I am using the recorder element in the following form:
recorder Node -file output.out disp -time -node all -dof 1 disp

Thanks a lot for your help,
Katrin

you can add a -dT deltaT? to the command line args (anywhere before the disp .. suggest after -time) .. if last time the recorder recorderd was t1 the recorder will next record when the time in domain, t2, is next >= t1+deltaT .. t1 is then set equal to the new t2 to determine for determining the next step to record at (not t1 = t1+deltaT)

Hi,
thanks a lot for your resonse!
I tried the following recorder line

recorder DOF1.out disp -time -dt 10.0 -node all -dof 1 disp

but it did not work (the output file was empty). I also tried the -dt 10.0 at different positions in the command line and with different recorder elements but it never worked. Could you send me a command line which had worked before than I could try it?

Thanks a lot,
Katrin

oops... I just noticed it should have been dT instead of dt - it works with no problems at all.
Thanks again,
Katrin
