hi

i am trying to study a flow over a truck, and especially the end part of the truck and how reduce the drag. i am starting with a simple model: cube, then i try to add some kind of vanes system. then i crated a brick around the previous volume. then i substract the brick with the truck and try to mesh the volume, but there is an error during the meshing.

can someone tell me if i am doing it correctly, and how can i mesh.

thank you yann

your geometry operations are not clearly understandable. please explain well. also what is the gambit error ?

hey thanks for your answer, well for the geometry, i can send it to you by email cause it is really difficult to explain. for the error in gambit: "Initialization failed; perturb boundary nodes and try again. Initialization failed to mesh 7 nodes. ERROR: TG_mesh_Domain failed with error code 1. ERROR: tetrahedral meshing has failed for volume volume 1."

thank you yann

Hi

Send me your geometry file (.dbs) via email.

Bye
