Hi all,
I am simulating boats which are free to heave and trim using interDyMFoam (OF-2.1.0). To make my simulations more efficient, I want to map a coarse mesh solution onto a fine mesh. I works perfectly as long as the object isnt moving. For some reason pointVectorFields (ie the pointDisplacement file) do not get mapped, even though they are required to run the simulation in the the target directory. I tried to grep the orientation (of the moving object) from the source directories pointDisplacement file and chucked it into the target directories file, but that is obviously not working. That draw a few questions regarding my understanding of mapFields and interDyMFoam:

Q1: Why are pointVectorFields not mapped?
Q2: How do I map the mesh deformation correctly?
Q3: Why is there a pointDisplacement AND cellDisplacement file, isnt that redundant information? Latter one is mapped OK.

Grateful for any advice!

Cheers, Max

Well I just figured out how to solve Q2: You simply specify (deformed) orientation and centreOfMass AND initialOrientation and initialCentreOfMass. The actual points will be moved accordingly by the solver and the cellDisplacement too. Too easy!
