NekMetl has Nek5000 matlab codes for helping users to understand the essential components of Nek5000 based on the spectral element method (SEM)[1] and allowing users to experiment a new algorithmic implementation and its anaysis in an easier way using the matlab codes.

This includes demo codes:

• Spectral element discretizations (basic components)
• Spectral element multigrid Poisson solver: run mgrid_demo.m
• Spectral element Navier-Stokes solver: run nst_demo.m

More to be added (eg., projection, jacobian-free newton, etc)

The matlab codes are authored by Paul Fischer ([email protected], [email protected])
