I would be interested in an answer to that question as well.

In my current project I want to calculate the groundwater inflow into several wells inside a building excavation in accordance with a predefined hydraulic head at the wells using FEFLOW 7.1.
For example, the natural phreatic level is located at -10 m and for a construction site I have to lower the phreatic level to exact -20 m. What is the best way to do that?
Using 'multilayer wells' just makes the definition of a well capacity possible and I would have to find my solution iteratively.
Attached you will find my current model.
Thank you!

Hello,
another question I have is: Which possibilities do I have to reduce the errors during a simulation. I know that you have to check your 'Boundary Conditions' for any conflicts and that 'Delauny criterion', 'Peclet & Courant number' and 'Condition number' are good hints as well as 'Max. interior angle of triangles'. But are there other ways to reduce it?
Thank you in advance!
Best regards,

Thank you for the fast and satisfying response!

Hello,
is there a way to fix/to anchor single nodes? Would be useful for optimizing the meshing, so that you fix nodes and let the surrounding get smoothed.
Thank you!
