Hello everyone,

Currently I am running a case and for this especial case, in order to avoid divergence I run the code for 500 iterations with dt=0.001 and then run the rest of the case with dt=0.01. At the same time I need to auto-save the data at round time scales (t=20, 25, &hellip. Can you please tell me how I can do that?

Thank you, Pirooz

Before giving iterarations

file-->write--->autosave--->for every 50 iterations you can use overwrite to save the memory

there is a way to write out at specific time steps. using autosave will only store every n iterations or time steps and with varying time steps or number its/step this will vary so you need to write according to flow time. there is a way i recall you may need a udf or scheme. have to check.
