Meshing from given nodes and geometry

Hello

I imported 8832 nodes in Hypermesh and created a surrounding geometry or surface i should say. Now can anyone help me about how to mesh this? While meshing with new geometry i want hypermesh to use the existing nodes as they are and create additional nodes to mesh the new geometry. How this will be possible to mesh a new geometry with imported nodes in that geometry? Can anyone please help me regarding this?

Regards
