Replace mesh , py

Hi.
Got stuck on something,never used the replace mesh before with py:

replaceMesh(mesh, useDisplayMesh=True, usePhysicsMesh=False)

I shall use my mesh name,but I dont know how to define it.

Thanks.

Sorry mates,just found out! Thanks anyway.And sorry for posting this thread.

own.replaceMesh(‘high’) << the response to my problem.
