[Gridgen] boundary condition for single point
 

I am a rookie user of Gridgen. Can I prescribe boundary condition to a single point on the boundary face, particularly, a corner point? So far I can see that the "set BCs" option is only available for boundary faces. Since I am working on the standard finite element method for CFD, I do need to treat some special boundary points individually. Thanks so much if you can shed some light on me!

Currently there is no method to specify a BC at a point, possibly needed for FEA simulations where point loads or moments need to be applied.

Pointwise, the successor to Gridgen, has a CAE export API whereby you can develop a custom library to export your mesh and BCs to whatever format you desire. It's possible that point-based BCs could possibly done within a custom export plugin.

Thanks a lot for your reply. :)
