Hi, I am using Feflow6.0. My area has two aquifers(confined and unconfined). I have divided into 5 layers based on lithology and alloted necessary parameters , initial head etc. But after simulating the first slice alone is not responding. The hydaulic head value and elevation goes to very very high values. I dont know why this happens. I get high peaks in the first slice which makes the entire model wrong. I checked my boundary conditions too. it been given correct.

Kindly help me
Thank you

Did you also check the budget? Is the groundwater recharge reasonable? Is the imbalance small enough? A large imbalance indicates that the model is not converging.

Yes Sir i do checked the budget. the difference between dirichlets BC is small and between neumanns boundary is more comparitively. This is a problem in that case?? Because the recharge has been assigned reasonably.

Thank You

Thanks, I was actually asking whether or not the imbalance is small enough? A large imbalance is an indication that the model is not converging.
