Hi there! I am a new Foamer who just stated with OpenFoam recently. I am trying to simulate with the k-epsilon model the flow over the Askervein hill. I started looking at the turbinesiting tutorial and then tried to use it as a base for wind study. I have encountered some problems when trying to run the solver SimpleFoam after having imported the Askervein.stl map and having meshed it with SnappyHeshMesh. I get this message error

Apparently it cannot even start the simulation. I see that the problem could be related to the inlet velocity profile. Some questions arise when thinking in how they define the inletvelocityprofile function:
-Why is z_ground a input parameter as it could vary in the spanwise direction?
Is it because it is thought that the inlet should be at the same height?

I use the boundary conditions that come by default, so I basically just tune the inlet velocity and the turbulent kinematic energy k. Has anyone used this tutorial to do some wind simulations over small hills?
If somebody could give me a hint in what the problem could be and give me some advise on how to pursue in this case, I would really appreciate it.

Thank you in advance,

Ben.
