Hello,

I am having trouble selecting the right mesh for what I am doing:

External Flow Aerodynamic Air over Vehicle Tanker

It is a complex component which I have tried to simplify.

I am planning on running a turbulent model (likely SST), however am not sure what mesh properties to use to generate a flow of decent accuracy.

Usually I will insert an inflation around the whole body and select a face sizing. But I get the following warning:

"Pre-inflation layer generation are ignored for the following faces"

And so when I generate the mesh, the inflation layers are not present.

Is adding inflation layer and face sizing sufficient properties for mesh generation?

Is this to do with the CAD geometry discrepancies? What is the best way to solve this?

Hope someone can help.

Ive attached picture of the CAD model, and an inflation preview with green highlight of one "problematic geometry" face.

Thanks in advance!
