Cable Studio and Microwave Studio TLM solver are integrated in Studio Suite 2011. Is a single unified environment for all EMC-related modeling tasks, including simplified model setup and simulation. MWS TLM solver (Microstripes) and CS provide features for real-world EMC analysis, including coupled simulations that enable large system analysis and installed performance studies. In preprocessing, performs definition of compact equivalent aperture models and cable harnesses. Enhances coupling between the electromagnetic field and cable solvers to enable direct transient simulation of susceptibility problems in systems containing complex cable bundles, including shielded twisted pair circuits.
