how to generate the mesh in a parallel way?

I have a geometry file, *.stp, I import the file into the abaqus and obtain a "part".

I want to mesh the "part" using abaqus mesh module.

The geometry is a little complicated, I want to obtain up to 1 billion elements.

When meshing the part, I can found there is only one processor work 100% in the resource manager. That is, the mesh does not make full use of the all cpus.

How can I mesh the part in a parallel way?

Thanks for your time.
