Export results time series in coherent time steps

I would like to export the simulated (and observed) heads on a coherent time step interval, i.e., daily, for post processing (e.g., performance evaluation).<br> <br> While the observed time remain consistently on daily time steps in the model, the simulated time series do sometimes include additional intra-daily time steps, e.g.: <table style="border-collapse:collapse;width:54pt;border:none;" width=72> <colgroup> <col style="width:54pt;" width=72> </colgroup> <tbody> <tr height=20 style="height:15.0pt;"> <td class=xl64 height=20

time series.<br> <br> Is there a way to export the simulation results in the time steps as given/defined by the observed time series?<br> <br> Cheers

Hi Philip,<br> Indeed, your observation is correct. FEFLOW automatic time stepping scheme will not necessarily fit the times of the observed time series. If that would be the case, an improper time series can &quot;damage&quot; the model performance significantly. Therefore, if you export the results corresponding to the time series of the simulated values, the export function will include all time steps. There are two cases:<br> (1) If the export does also contain the observed times, then it is just a matter to filter and discard all other times. You can do this task e.g., with a script. You can also have your own script accessing the FEFLOW - Python interface to loop from time steps within an existing FEFLOW result file (*.dac) and then export only data at time fitting your reference.<br> (2) If the export does not contain data at the observed times, I would recommend you to do an interpolation in between FEFLOW simulated times.It is always a prefer solution, so you do not need to affect much the automatic time stepping with extra values.<br> <br> Please reach out support at mike.de@dhigroup.com for specific details.<br> <br> Best regards<br> Carlos Rivera<br> <br> &#160;
