NLOUT in Nonlinear transient
Hi
I am running a nonlinear transient analysis , Where i invoked TSTEPNL and NLOUT.
NLOUT does not give all time step results , but i want to see all time step results. or atleast i want get control of number of output steps.
I found some thing to create a time set and invoke it to NLOUT but that option is not available in the software. can any one please helpme.

Sir
Thank you for the respons.
I have attached a picture of output graph.(Acc VS Time).
To get the graph smooth , obviously we need to increase the number of time points(X Axis ) which is related to NLOUT.
NLOUT is not giving the specified number of output points. How can i control the number of those points .
This is really wasting lot of my time.can any one please help me.
All i want is just to get a control on output time points.
I also tried with creating time set and invoking with unsupported cards, But as the input load is having varying time steps ( high time steps from 0.0033) as show below
<?xml version="1.0" encoding="UTF-8"?>
I am getting output as below up to 0.0033 the curve is smooth and detail from time 0.0033 the out put curve is with large time steps So i dont want to use this method at all.

could any one help in solving this .

If you maybe attach your model or at least the relevant cards the forum members can help you much better.

Hi , did you solve your problem in the meanwhile?
I am facing the very same issue and can't find any solution.
Does anybody else know how to solve this (simple) problem?
Thanks

if you need specific values to be outputted, you can use the NLOUT option TIME, specifying a SET of type TIME, just like the attached example.

Thank you for your kind answer.
I am currently using HyperMesh 2019, which has not the option you proposed. As fas as you know, is there an equivalent option also for my HM release? (Considering that for some reason the number of intervals specified to output intermediate results [NINT] is somehow ignored).

As far as I remember, OptiStruct 2019.2 was the version that this option was implemented. So maybe your HM doesn't support it, but if you have OS2019.2 and edit the solver deck to add this, you should be fine.
NL Transient output results for the converged steps, and they can be adjusted accordingly depending on the convergence, and that's why you don't have the exact same steps in your output. The only option I know for that is using the NLOUT / TIME option.
Can you detail why you need results at these specific points, in your case?
Hi Naresh,
Kindly go through the attached post which will give you an idea on how to output every time step result.
