Investigators at Consejo Nacl Invest Cient and Tecn Describe Research in Computational Engineering

  2012 APR 17 - (VerticalNews.com) -- "We study the performance of direct solvers on linear systerns of equations resulting from isogeometric analysis," investigators in Santa Fe, Argentina report.

  "The problem of choice is the canonical Laplace equation in three dimensions. From this study we conclude that for a fixed number of unknowns and polynomial degree of approximation, a higher degree of continuity k drastically increases the CPU time and RAM needed to solve the problem when using a direct solver," wrote N. Collier and colleagues, Consejo Nacl Invest Cient and Tecn.

  The researchers concluded: "This paper presents numerical results detailing the phenomenon as well as a theoretical analysis that explains the underlying cause."

  Collier and colleagues published their study in Computer Methods in Applied Mechanics and Engineering (The cost of continuity: A study of the performance of isogeometric finite elements using direct solvers. Computer Methods in Applied Mechanics and Engineering, 2012;213():353-361).
