Rodrigo, X. Hu, P. Ohm, J. Adler, F. Gaspar, and L. Zikatanov, Comput. Methods Appl. Mech. Engrg., 341 (2018), pp. 467-484]. The discretization is proved to be well-posed with respect to the physical and discretization parameters and thus provides a framework to develop preconditioners that are robust with respect to such parameters as well. We construct both norm-equivalent (diagonal) and field-of-value-equivalent (triangular) preconditioners for both the stabilized discretization and a perturbation of the stabilized discretization, which leads to a smaller overall problem after static condensation. Numerical tests for both two-and three-dimensional problems confirm the robustness of the block preconditioners with respect to the physical and discretization parameters.</dc:description><dc:date>2020</dc:date><dc:source>http://zaguan.unizar.es/record/95553</dc:source><dc:doi>10.1137/19M1261250</dc:doi><dc:identifier>http://zaguan.unizar.es/record/95553</dc:identifier><dc:identifier>oai:zaguan.unizar.es:95553</dc:identifier><dc:relation>info:eu-repo/grantAgreement/ES/DGA-FEDER/E24-17R</dc:relation><dc:relation>info:eu-repo/grantAgreement/ES/MCYT-FEDER/MTM2016-75139-R</dc:relation><dc:identifier.citation>SIAM JOURNAL ON SCIENTIFIC COMPUTING 42, 3 (2020), B761-B791</dc:identifier.citation><dc:rights>All rights reserved</dc:rights><dc:rights>http://www.europeana.eu/rights/rr-f/</dc:rights><dc:rights>info:eu-repo/semantics/openAccess</dc:rights></dc:dc>
