Ship hull with appendage as seperate patch runs into error
 

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?
