Meshing a surface with an interior point

I need to apply a point force on a point inside a shell surface. For this purpose I draw a point in geometry section. However, because of that point I can't mesh the surface with free quad or mapped. It is giving the error "isolated vertices found".

In some other softwares it is possible to pick nodes from the mesh for this purpose. But I couldn't figure out how to do that in COMSOL.

I appreciate any help.

Thanks
