Dear all,

I built a 3D model with 7 layers. In addition, a well is installed in the middle of the model (delivery rate set via Polyline). While pumping I get a problem in the two upper layers. In this part the head starts pumping instead of sinking. There are no problems for the remaining layers.
Does anyone know where the problem could be?
I upload my data and in addition, a picture in which the distribution of the head for the individual centers of the respective layers are seeing.
Order of layers from top to bottom: KOH-0, KOH-1, Aq-1, KOH-2, Aq-2

Best regard,
Leandra

Correction: In this part the head starts RISING instead of sinking

Dear Leandra,

can you please add the .asc files (reload data)?

Best,
Marc
