time steps - dac file - budgets

Hello,

I’m running a transient groundwater-heat transport model over 365 days. I’d like to calculate rate budgets for daily values. In the problems settings I chose automatic time step control – because with a constant time step of 1 day, the simulation did not converge at some time steps (maybe too low number of maximum iterations?).
If I now produce the .dac-file for all simulated time steps (e.g. about 680 steps in my case due to automatic time step control), can I somehow calculate/export the rate budget for daily values from the dac-file, or would I have to calculate the daily values e.g. from the exported txt-file “by hand”?
If I produce a dac-file with user defined time steps (only 365 days), then the intermediate time steps are skipped and the budget will be biased somehow.
Can someone help?

Thanks

Matthias

You can specify time steps to save in addition to the steps computed via the automatic stepping. Simply specify that feflow save all time steps including specified ones, for example at the end of day 1, end of day 2, etc.  Feflow will automatically insert these specified times into the time stepping sequence so that you can use the resulting dac to compute daily budgets that are not missing simulation data. However, you would still have to do some filtering of the resulting output to list only the budget information at the end of each day. See screen capture.
