Hello All,

This is my first post and I am trying to teach myself OpenFOAM, so please bear with me ...

I am trying to perform a simulation over Alcatraz Island using the turbinesiting tutorial. I believe I have successfully generated a grid over Alcatraz Island with blockMesh and snappyHexMesh (at least the logs show no errors, and I am able to view the mesh fine in paraFoam).

However, when running the simpleFoam executable, it crashes quickly with the attached log file.

I tried to simplify the initial conditions and not change much from the turbinesiting tutorial. I was able to successfully run the turbinesiting tutorial to completion.

Any hints? Do I need to show you more to help me?

Thanks!

-Matthew

It looks like it crashed when it was reading your U field. It was in the middle of constructing the geometricField for U, was building one of your boundary patches, an "atmBoundaryLayerInletVelocity" boundary condition, and failed when it was trying to update the cofficients. The function is located at:

src/turbulenceModels/incompressible/RAS/derivedFvPatchFields/atmBoundaryLayerInletVelocity/atmBoundaryLayerInletVelocityFvPatchVectorField.C: 145

As for why, I'm not sure. Try putting a simpler boundary condition there and seeing if it still crashes when trying to read U. It may be the mesh.
