Novel high performance numerical solution techniques for RCS computations

TECSER is a project funded by the French armament procurement agency in the framework of the Specific Support for Research Works and Innovation Defense (ASTRID 2013 program) operated by the French National Research Agency
Starting date: May 1st, 2014. Duration: 3 years

Scattering of a plane wave by an aircraft geometry. This numerical simulation was performed using a hybridized discontinuous Galerkin HDGFD-P1 method for the discretization of the frequency domain Maxwell equations in 3D combined to a domain decompositon based hybrid iterative-direct solution algorithm for the resulting system of algebraic equations. The underlying tetrahedral mesh consists of 357,038 vertices and 1,970,770 elements. Inside each element, the components of the electromagnetic field are approximated by a linear interpolation method (the total number of degrees of freedom for this problem is 47,298,480 for the hybridized DGFD-P1 method). The simulation was run on a 128 cores parallel system (Intel Xeon 2.66 Ghz) and took 350 sec.
