Abstract:
The discrete approximation scheme of the lumped mass nonconforming finite element method are discussed for nonstationary Stokes problem (Crank-Nicolson fulldiscrete scheme).Without using Stokes projection,the optimal error estimations of the velocity and pressure are derived based on interpolation technique.
Key words: lumped mass; Stokes problem; Crank-Nicolson scheme
