12 Why is the T-solver faster? Rectangular structure aligned with hexahedral mesh PBA perfect for planar structures High density of surface current at the patch edges No problem in TD only few mesh cells Large number of 2 nd order tetrahedrons in FD CST workshop series 2010 February Patch on Cylindrical Substrate 3 hours 30 min CST workshop series 2010 February

13 13 Patch Array on Conical Substrate 2,146,588 mesh cells (Subgridding reduction factor 7.87) Simulation time: 20 h 39 min 247,425 Tetrahedrons Simulation time: 2 h 50 min CST workshop series 2010 February Conclusion Different antenna types different geometries different physical mechanisms different simulation criteria! Multiple solvers allow optimal simulation of many different antenna types. CST workshop series 2010 February 10 26
