Ramp output frequency using NFRAMES

[r-broek]

Hi!

Is it possible to use a RAMP to adjust the value of NFRAMES to control when FDS should start outputting data? If so, how would that work? I have read that the frequency of particular output files can be adjusted, however, I would rather not do that for every output file class.

For context, I would like to run a simulation with T_BEGIN=-10 and T_END=10 but only want data for $T\geq 0$.

No, there is not a way to do what you want. However, you can create a single set of RAMP lines and have all the relevant RAMP_XXX parameters on the DUMP line point to it.

Thank you!

If I understand correctly, RAMP_XXXX specifies discrete timestamps for data output. Let's say I want to output data every 0.5 seconds, does that mean I need to manually input $T=0, T=0.5, ...\ T=9.5, T=10$? Or is there a way to give a timestamp range?

Yes, you would have to do that.

Thanks again for your response.
