Problem meshing an object.

Hello,

I have an issue with meshing an object.

I try to mesh a plane model obtained with 3DS Max, which provides a .stl file.

This .stl file is read as a mesh by Feko ("Import/Mesh") :

In order to mesh it correctly, I set a frequency (100MHz) then right click on the mesh ("Use model mesh") :

Apparently, the model is correctly meshed :

, but flaws appear on closer inspection :

One can see that there are holes in the meshing, and even stranger, some triangles are not complete :

I've tried all the settings in the "Meshing/Modify Mesh" tab, but I can't get a correct mesh.

Would anyone recognize a well known error and have a way to solve it ?

Thank you in advance.

    HI @Student ,

    Maybe one other observation that may be causing confusion here:

    I see that you have the Overlay display mode on and you are (therefore) seeing both the mesh and the geometry at the same time in the 3D view. In some places, the mesh view is being obscured by the underlying geometry. 

    If you change the display mode to only show the mesh

    - Either on the Ribbon under Display Options, so that the setting is as follows:

    - Or in the quick actions available at the bottom of the CADFEKO windows (as shown below):

    I believe that you may be able to see the mesh more correctly and you may find that the mesh is infact 'good'.
