Hi everyone,

I am running interFoam to solve flowfield around ship hull. I am using the DTMB model. For LTSInterFoam the solver can run well. However, when I change to interFoam I found that drag and lift forces equal 0 for every time step as shown in the attached file.

Could someone please tell me why that and guide me the way to correct it.
I am really appreciate.
