Microwave modeling and simulation specialist Computer Simulation Technology (CST) has announced true geometry mesh adaptation capabilities for its CST Microwave Studio electromagnetic (EM) simulation software. The advance, which will be available with version 2009 of the company's software suite, provides a total revision of the tetrahedral frequency-domain solver's traditional mesh adaptation scheme.

In traditional adaptive mesh approaches, a tetrahedral grid is fitted to a structure under study, but the initial grid does not improve or adapt to modifications in the structure as analysis and redesigns are performed. With the new mesh adaptation approach, nodes of a newly created tetrahedral mesh are not simply placed on the edges of existing ones, but are projected back to the input model for back-and-forth feedback and refinement of the mesh as a part of further analysis. CST's Managing Director (MD), Dr. Bernhard Wagner, notes: "Once again, CST has achieved a breakthrough in simulation technology. Insightful market intelligence and pioneering development ensures that our software and its users stay several steps ahead of the field."
