Hi, I am trying to simulate flow through an orifice plate. My aim is to determine discharge coefficients at various reynolds numbers. However before i get there i am having a few issues meshing the model which can be found here… https://www.simscale.com/workbench/?pid=3126067294385075099&mi=spec%3A98d29b85-5848-4ce3-bdfd-272842703310%2Cservice%3ASIMULATION%2Cstrategy%3A59
The geometry is axi-symmetric so i am trying to make use of that by using the wedge BC. There are no issues with using either a standard or tet dominant mesh … however i am unable to mesh using HEX mesh, i am wondering that this is because of the geometry as a result of it converging to a point at the axis of the cylinder which means you need a wedge element in this location. Is there a way of doing this in simscale ? Or maybe a better question would be… what is the best practice for meshing this problem?
Appreciate any help given,. Thank you, Ross
