Guaranteed a posteriori error estimates for obstacle problem for elastic deformation of membrane
Harasim, P.; Szarkova, D.; Balko, L.; Valdman, Jan; Richtarikova, D. (Slovak University of Technology in Bratislava, 2015)We apply functional a posteriori error estimate proposed by S. Repin for numerical solution of obstacle problem for membrane. Numerical solution of the obstacle problem is obtained by the finite element method using bilinear ... -
Verification of functional a posteriori error estimates for an obstacle problem
Simos, T.E.; Harasim, P.; Tsitouras, C.; Valdman, Jan (American Institute of Physics, 2015)We verify functional a posteriori error estimate proposed by S. Repin for an obstacle problem. A new benchmark with known analytical solution in 2D is constructed. Numerical approximation is obtained by the finite element ... -
Verification of functional a posteriori error estimates for obstacle problem in 2D
Harasim, Petr; Valdman, Jan (Ústav teorie informace a automatizace AV ČR, 2014)We verify functional a posteriori error estimates proposed by S. Repin for a class of obstacle problems in two space dimensions. New benchmarks with known analytical solution are constructed based on one dimensional benchmark ... -
