I have many meshes like the one shown below which have some faces/vertices that are not connected to the main mesh. I use these meshes for physics simulation. As result of these weird parts of the meshes the physics simulation results becomes very different than what it is supposed to be. I wonder, what would be an effective solution to remove such parts?

I have tried "Delete Loose" in Edit Mode but it doesn't do the job. I was also thinking of writing a script to calculate the average of the faces and then remove the vertices that are further from that "average face" but I don't think this would work well based on my prior experience on doing a similar thing before.

One thing I could recommend is to select the large object with the hotkey [L]. If there are several islands (isolated parts of the mesh) that you want in the physics simulation, you can select those too. once you have all of the mesh you want selected, then press control I (invert selection) and delete. That should get rid of any unconnected geometry

Go to edit mode Press Z to be in wireframe mode. Press Ctrl+Left click like lasso tool draw on unwanted verts you need to delete. After you draw it will select the verts Press Delete and select verts.

    $\begingroup$ You can just do the above method to the main model and Press ctrl+I and reverse and delete it $\endgroup$ – atek Jun 7 '18 at 11:28
