CST Microwave Studio version 2011 SP3 has finite element-based eigenmode solver, alongside finite integration technique-based eigenmode solver. Features curved elements of arbitrary order; elements enable conformal representation of geometry that provides simulation accuracy. Includes high-performance computing options. Transient solver now supports NVIDIA Tesla 2o series. MPI-based parallelization is available for integral equation solver with MLFMM.
