Can we get your input model so we can duplicate your example?

Can you just show how to import 2D STEP file? If have problems to define the plane surface.

I can't delete the mesh the way you did it

Hello, thanks for your videos. I couldn't do the final step, I don't know how you import and visualize the mesh on Matlab.

I am trying to develop a case study for teaching CFD. To this end, I am using OpenVSP, Gmsh and SU2. I have created a wing in OpenVSP, exported the CFD mesh as .stl file. Opened the .stl file in Gmsh GUI and added a box. How do I create a 3D mesh with markers and export it in SU2 format? In this case I want to treat the 'wing' surface as one marker (EULER) and box as FARFIELD . The geo file is Merge "wing1.stl"; SetFactory("OpenCASCADE"); Box(1) = {-20.0, -20.0, -25.0, 35, 35, 35}; The wing is just a default wing which is in OpenVSP. Apologies for asking a basic question. but any suggestions will be greatly appreciated.
