[Nek5000-users] over-integration

[nek5000-users at lists.mcs.anl.gov]

Hello
nek5000 can use over-integration for the quadratic nonlinear terms by
setting lxd, lyd, lzd. Is it possible to use this for integration to
approximate some integral like applying Biot-Savart law ? I have seen the
use of the mass matrices bm1 and bm2 on the velocity and pressure meshes.
Is there a mass matrix on the mesh (lxd,lyd,lzd) also which can be used for
integration ?

I have read about the use of over-integration as a stabilization method.
Can you suggest some papers/books which discuss the theory behind this ?

Thanks
praveen
