Manufactured Solutions for Verification of a Coupled Flow and Material Response Code

Abstract

The Method of Manufactured Solutions is used to perform order of accuracy code verification tests on some features of a hypersonic computational fluid dynamics (CFD) code and a material response code. The CFD verification tests include results for a two species gas mixture in thermal nonequilibrium, and the material response results are for an anisotropic material. After verifying the two codes separately, a verification test is performed with the codes loosely coupled so that the material response code provides updated boundary conditions to the CFD code. In the cases tested, the observed order of accuracy of the CFD code is less than the theoretical order. The tests of the material response code, however, show the expected order of accuracy.
