Hi all,
I'm using STAR CCM+ version 7 and I'm currently trying to write a field function to define the motion of a wall of an expanding and contracting vessel. The flow is assumed Laminar and a Mesh morpher solver is employed. I need to apply a periodic sinusoidal function to the wall such that the radius varies with time. The radius of this region should expand from 60µm to 120µm and contract from 120µm to 60µm over a period of 3 seconds (1 Cycle). The wall motion is being applied as a boundary condition, so no FSI modelling is currently involved. I'm having great difficultly with this task, any help at all would be greatly appreciated. Cheers |
