Convert .obj file into .hmascii (hypermesh database file)

Hi there:

I'm working with 3d Scan files which just allow to be exported as *.obj or *.wlr. *obj file just seems to be a list of coordenates. I'm trying to convert it into some format that is supported by Hypermesh to mesh it into a solid for CFD studies. Does anyone know how to do this conversion?

Thx!
