Computer Simulation Technology AG (CST) announced True Geometry Adaptation at EuMW 2008. This represents a breakthrough in high frequency tetrahedral frequency domain solver mesh adaptation schemes. This innovation will be available with version 2009 of the electromagnetic simulation software CST MICROWAVE STUDIO® (CST MWS).

Users of CST MICROWAVE STUDIO® (CST MWS) version 2009 will benefit from the total revision of its tetrahedral frequency domain solver’s mesh adaptation scheme. Traditionally, adaptive mesh refinement of HF frequency domain solvers, based on a tetrahedral grid, does not improve on the initial, facetted representation of the structure. The originally created tetrahedra are just divided further where necessary. Here the mesh adaptation will converge, not to the results (e.g. S-parameters) of the actual structure, but to those of the initial, segmented model.

CST’s new mesh adaptation approach is different. The nodes of the newly created tetrahedra are not simply placed on the edges of already existing ones, but they are projected back to the input model, they literally “snap” to the original geometry. With the release of CST MWS version 2009, CST is the only commercial vendor to offer a high frequency Finite Element type solver that accurately converges to the real solution, even for rounded structures. This new technology is another milestone in CST’s history.

“Once again, CST’s has achieved a breakthrough in simulation technology,” said Bernhard Wagner, managing director, sales and support, CST. “Insightful market intelligence and pioneering development ensures that our software and its users stay several steps ahead of the field.”
