DOI: 10.1080/01630563.2017.1338730
Abstract: ABSTRACT We study residual-based a posteriori error estimates for both the spatially discrete and the fully discrete lumped mass finite element approximation for parabolic problems in a bounded convex polygonal domain in ℝ2. In particular,… read more here.

DOI: 10.1142/s1758825121500137
Abstract: A mid-node mass lumping scheme is proposed to formulate the lumped mass matrices of serendipity elements for accurate structural vibration analysis. Since the row-sum technique leads to unacceptable negative lumped mass components for serendipity elements,… read more here.
