Grid Modification for Second Order Hyperbolic Problems
A family of Galerkin nite element methods is presented to accurately and e ciently solve the wave equation that includes sharp propagating wave fronts. The new methodology involves di erent nite element discretizations at di erent time levels; thus, at any time level, relatively coarse grids can be applied in regions where the solution changes smoothly while ner grids can be employed near wave ...
متن کاملInitial value problems for second order hybrid fuzzy differential equations
Usage of fuzzy differential equations (FDEs) is a natural way to model dynamical systems under possibilistic uncertainty. We consider second order hybrid fuzzy differentia
متن کاملSecond-Order Domain Decomposition Method for Three-Dimensional Hyperbolic Problems
In this paper, a non-overlapping second-order domain decomposition method for solving three-dimensional hyperbolic partial differential equation is proposed. Unconditional stability of the algorithm is analyzed. Numerical experiments show that the method is stable and very efficient. Mathematics Subject Classification: 65M06, 65M55
متن کاملDiscontinuous Galerkin finite element methods for second order hyperbolic problems
In this paper, we prove a priori and a posteriori error estimates for a finite element method for linear second order hyperbolic problems (linear wave equations) based on using spacetime finite element discretizations (for displacements and displacement velocities) with (bilinear) basis functions which are continuous in space and discontinuous in time. We refer to methods of this form as discon...
متن کاملOrder-type existence theorem for second order nonlocal problems at resonance
This paper gives an abstract order-type existence theorem for second order nonlocal boundary value problems at resonance and obtain existence criteria for at least two positive solutions, where $f$ is a continuous function. Our results generalize or extend related results in the literature and give a positive answer to the question raised in the literature. An example is given to illustr...
