Hi Everyone

My ship hull has an appendage below the hull. My objective is to find out wave resistance on hull and total force on the appendage.. With this in mind, I was trying to do a simulation with the hull and appendage as separate patches, so as to report the forces separately. I was trying to do a dynamic trim and sinkage simulation to account for the trim and sinakge that the hull with incur at the given speed. But when I run the simulation it gives error. I have attached the log file as well as the setup file. I have also trying running it without 6Dof utility and in serial, but I get same error.

Error:

Please help me to run it correctly.

I am using Openfoam 3.0.0.

Since the error happens before the solver executes and when solving for correctPhi I take it it's most likely due to the mesh. Can you try running checkMesh and reporting the outcome?
