Meshing with Ennova-CFD. The Ahmed body geometry (with wheels)

✌️ Ennova-CFD, the better CFD meshing solution

Real-time step-by-step video tutorial that demonstrates how simple it is to manipulate geometries, create meshes, and set OpenFOAM cases using EnnovaCFD. 

For this demonstration, we used the Ahmed body geometry with a little twist; we added wheels to make things a little bit harder. For solid modeling, we used Onshape; you can find the document at the following link,
