Hello outthere,

I would like to use PEST in a seepage-problem though a large concrete retaining wall where we have transient pore water pressure and temperature observations inside the structure. Until now we are familiar with the built in PEST2.0-option. This older PEST-version apparently does work only for "real" groundwater models .

Does PEST12.1 work for vertical plane unsaturated flow and transport problems?
Are there any example files, that would allow me to accommodate our model to the in-/out-put structure required by PEST?

Any hints warmly appreciated!

Hi Hector,

I don't know if there is a simple manual... I think the only bottle neck is the interface which is not necessarily implemented in FEFLOW already ( not able to do unsaturated flow into PEST for example), but if you work only using ASCII file  without the FEFLOW interface, you should be able to optimize any kind of model. You can download the  PEST manual into the
