define a cellzone with toposet

decibelle · June 7, 2017, 07:24

Hi,

I work on OF 1.6 on a case of external aerodynamic. I made my mesh with snappyHexMesh, you can see the result on the picture (it is a slice).

I would like to move the capsule (oscillation and rotation) inside the mesh with pimpleDyMFoam. To do this, I created dynamicMeshDict file with solidBodyMotionFvMeshCoeffs and oscillatingRotatingMotion. In this file I need a cellZone.

my problem is to create this cellzone. I created a topoSetDict file and I tried to define a cellzone with surfaceToCell, boundaryToFace or PatchToFace but it doesn't work all the mesh oscillate.

someone can help me?

thanks in advance

I joined the toposetdict file

can you post the dynamicmeshdict and blockMesDict?

Hi, I'm also having troubles to define the cellZone in order to use solidBodyMotionFvMesh, could you please share how you solved your problem?
