Steady-state convergence while changing K in FePEST

Hi,

I am trying to do a steady-state calibration with FePEST with strict constraints on the hydraulic conductivity (and using only hydraulic conductivity). Before FePEST is used the model converges to below the error tolerance. But after FePEST is used, the model no longer converges.

I am wondering if there is a way to check to see if the model still converges in FePEST... It would be handy on making some diagnostics on my model. Or perhaps a way to set a criterion to terminate the FePEST run if it stops converging.

Thanks,

Adam

For a stability test you could try to use JACTEST. http://www.feflow.info/html/help71/fepest/09_Tools/pest_tools.html
