problems with displacementLaplacian motion solver

i have problems solving the meshmotion with the displacementLaplacian solver combined with the movingMeshVelocity boundary condition for U.
I seems that the fluid sovler (i use the pimpleDyMFoam) is doing something wrong when it solves the pressure.
The velocity seems ok.
Are there special instructions for using this combination of motion solver and BC?

thanks a lot

Hi again,

it seems that the problem comes from the diffusion term of the Navies-Stokes equations...

could there be a problem?
