My velocity boundary condition on the moving wall is movingWallVelocity.
I am testing the same case with 3 different mesh, and with different timesteps, and I am still having the problem.

I've just changed the geometry of the problem, and everything seems to be working... In a first time, it was a 30mX30mX70m domain, and now, it is 12mX12mX20m domain... Don't know what was the problem, but everything is working fine now!
Thanks Hrvoje for your help!

O.K. Still me! but with good news!
After changing problem geometry, I still had the sams problem with "peaks" of pressure when adding new layers, but because my mesh was not so fine, this error just vanished. But at some times, when the speed of the falling object was great, I still hat the same problem reported earlier...
I think I found what was the cause of the problem, after having a look at turbDyMFoam in the svn. On line 62 of turbDyMFoam : p.storePrevIter();
This command is not there in icoDyMFoam. After adding it, no more problem with my solver!
