What is the length of the OW-HW bond, and what do you expect? It
should be exactly what the FF specifies, assuming you used SHAKE
in GROMACS.

In TIP3P, a bond is made between the water H's to keep the water
rigid, so if you were using TIP3P in GROMACS, there should have
been the H-H bond there, too.
