Replies: 9 How can we effciently mesh for these type of geometries? Views: 1,616 Posted By ghorrocks Work out a function for the drag of your body... Work out a function for the drag of your body versus velocity. You should be able to do by assuming it is a cylinder and using the well known cylinder drag for this Re range. Then read the...

In that case forget about meshing this feature and impose its pressure drop as a momentum source term. This will be much easier and just as accurate (maybe more so). The only reason to directly model...

You still have not answered the critical question - how big is the object, or what Re number does it run at? Also, why are you modelling this rather than imposing its effect as a momentum sink...

The type of mesh which is approriate also depends on the type of model you plan to do. If this is a 1mm wide liquid stirrer you would mesh it entirely differently to a 1km across wind turbine.
