I'm running a transient FEFLOW model that starts from initial heads that I set through Flow data -> Flow Initials->Hydraulic Head (Database) slice by slice.  As I make changes and run the model repeatedly, I noted that the initial heads change.  To get the project done, I reset them for each model run.  Is there a way to keep initial heads fixed?

When Feflow runs, if you save the .fem after the run, it will overwrite the initial heads in the model with the final heads from the run.  To avoid this, you need to save the .fem before you run the model, but do not resave it after it has run.  You can save the results in a .dac file and then open that to view them.

Thanks, Gemma.

Dear PMock,

when you are vieweing your results in the dac - File, you can reassembly your initial FEM - File with the function:

Recreate > Rehash F.E . problem.

Then Feflow creates a fem - file with the initial slice definition but with the resulting heads. You can use this created fem - File as a better fitting new initial fem - File.

best regards, henilein

When I do run transient FEFLOW models I normally make a copy of the initial head before I start the run. An easy method to do this is to copy it to a nodal reference distribution (from the initial head menu --> copy). So then you got all in the femfile. If you want to rerun the model yuo can go to reference distribution and copy this back to initial head.
