same node number for surface and volume mesh

Hi, I mesh my model in Hypermesh. I first mesh surfaces and then use the tetrahedral option in 3D, and mesh my volume. Now My problem is that the numbers of elements and nodes, for surfaces and volume is not the same. is it possible the number for both be same? because I saw another model from my friend who meshed in another software, and all the surface and volume mesh has the same number.
