FAILED TO MEET SOLVER CONVERGENCE CRITERIA IN TIME STEP 1 OF STRESS PERIOD 1

[Jason Marz]

The MODFLOW file runs successfully, but through the modflow.out file, it is found that the model does not converge in STRESS PERIOD 1, and converges in all other STRESS periods

Why is that?

Hie Jason

I had the same problem earlier,  I then tried to add the GHB (General head boundary) package to my model and it worked. Maybe try that too. 

Kind regards

Natasha

Hi,

Increase the number of iterations to 5000 and change the solver from simple to complex.
