| Abstract | Several classes of important engineering problems – in this case, problems exhibiting sharp thermal gradients – have solution features spanning multiple spatial scales a nd, therefore, necessitate advanced hp finite element discretizations. Although hp-FEM is unavailable off-the-shelf in many predominant comm ercial analysis software packages, the authors herein propose a no vel method to introduce these capabilities via a generalized finite element method non-intrusively in a standard FEA platform. The methodology is demonstrated on two verification problems as well as a repres ntative, industrial-scale problem. Numerical results show that the techniques utilized allow for accurat e resolution of localized thermal features on structural-scale meshes without hp-adaptivity or the ability to account for complex and very lo calized loads in the FEA code itself. This methodology enables the user to t ake advantage of all the benefits of both hpFEM discretizations and the appealing features of many avai lable CAE/FEA software packages in order to obtain optimal convergence for challenging multiscale pro blems.
