The use of certain nonconforming schemes for solving viscous incompressible flow problems was put on a rigorous foundation, and the resulting theory was used to construct new convergent schemes. The investigator was able to show that a certain nonconforming quadratic element actually has the same accuracy as a well known nonconforming cubic. This is of great practical significance because the costs of implementing the quadratic elements are far less than those for cubics.
