I am trying a simple simulation where a cross is rotating inside a cylinder. My problem is that the mesh does not update.
I have modified angularOscillatingDisplacement boundary condition for circular motion and used that boundary condition for the rotational movement. Could someone please help me correct this case? Perhaps the problem is trivial but I can't find whats wrong with the case. Here are link to the case and boundary condition. http://www.mediafire.com/download/xi...trv3/cross.zip http://www.mediafire.com/download/74...arVelocity.zip |

The problem with my simulation is that the motion of the boundary is right but the mesh does not update.
I still think that I do not understand the slipPatches and freeLengthScalePatches conditions so well. To me slipPatches are the boundaries with some constraints or fixedValuePatches. And freeLengthScalePatches are the boundaries where the length scale of the mesh is calculated by the motion solver. I have played around with everything but the mesh simply does not update. I hope this is the right thread to ask questions about mesquite motion solver. |

Greetings Paritosh,
As I mentioned in a private message I sent you a few days ago, I've had these 2 posts of yours on my to-do list for quite sometime now. I've now moved these two posts from the original thread http://www.cfd-online.com/Forums/ope...ofvmesh-3.html - to an independent thread, to make it easier to address your issue in particular. I'll quote a part of one of the private messages you've sent me, since it provides important details: Quote:

Thanks for answering my queries. Also its good to move the discussion here so that others can benefit too!!

I am using openFoam 2.3.0. The tutorials circCylinder3d, circTest, circCylinder3d and movingCylinders ran fine and I tried to use setup from these tutorials to create my own case. |
