Wrong mesh


#1

Good morning,

I was trying to generate my first mesh of an ahmed body but when I generate the mesh everything is right excet that it meshes my solid instead of the mesh box. I don’t know why it is hapening, if someone can please help me I would appreciate it a lot.

This is the link to my project:

Thank you in advance and regards.

Hi Antonio!

The explanation is quite simple. Your material point is inside your Ahmed body which should not be the case as you want to perform an external flow simulation. For internal flow simulations like a pipe the material point has to be inside your geometry! A nice template from my colleague @sjoshi can be found here: Aerodynamic Flow Around An Ahmed Body

Hope that helps!
