Hi,
I'm new to dynamic meshing, I need to lower the computational cost of my problem. My idea was to use dynamic meshing to accomplish this, however since I have no experience with it I need basic guidance on whether or not this is even possible. Water / oil is simulated in a capillary which is otherwise filled with air. I want to define various coarse / fine zones within the mesh. Part of it will be filled with the fluid. At first I will do a 1s simulation without gravity until the curvature is stable, then gravity will be activated and the mesh sorrounding the fluid has to move with the fluid. I need to do this to get a high resolution fluid/gas interface, which will be necessary for follow up simulations (marangoni flow, heat transfer within that region etc.) I understand interfaces between coarse and fine meshes need to be modeled because they are matching surfaces with different mesh topology. How do I manage to apply movement v(g)? Is the 6DOF solver appropriate? Any help regarding setup is very much appreciated, especially because the movement v(g) can't be defined as a value, since it will change throughout the simulation. |

So far I've tried sliding mesh, two adjacent zones have contact via interface.
Dynamic mesh is activated (layering etc. all deactivated) and one of the zones has been set to a fixed translational velocity in cell zone conditions. Interface options is set to periodic boundary condition. I don't get any movement whatsoever even though it is specified and I get no errors. |

Hi, I have approximately the same problem and I can't do anything about these two complexities in one problem. my problem is cooling of a moving disc by an impinging oil jet.
Do you have some advise for me? |
