Help regarding pimpleDyMFoam, avoiding stretching and squeezing of mesh
 
Hi!

I am, as the topic might reveal, new to this OpenFOAM-software and other CFD-tools. I'm currently running OpenFoam 2.0.1.

What I want to do; I want an object to be lifted of the seabed for some distance, without the stretching and squeezing which happens when i try to run the pimpleDyMFoam/movingCone - tutorial.

As I've been checking out the solvers/incompressible/pimpleFoam/pimpleDyMFoam/Make and options file, it is including the library ltopoChangerFvMesh, but i don't know how to make it happen, namely removing and adding cells when the cells reaches a certain thickness.

I've been searching the forums for some time, but it seems to me that the earlier version (like 1.4) had this functionality standard.

Any help would be much appreciated!
Best regards
Magnus
