The latest release of the Opera electromagnetic (EM) simulation software, from the Vector Fields Software product line of Cobham Technical Services, features improved speed and accuracy by merit of more flexible finite-element-analysis (FEA) meshing. The software also includes numerous further enhancements, including an integrated graphical circuit editor for defining associated electrical circuitry. Version 14 of the software extends this fundamental performance advantage substantially by increasing the range of FEA meshing shapes that may be employed to break down a three-dimensional (3D) model into smaller connected elements to simplify numerical solution. Cobham Technical Services' Alex Michaelides reports: "Meshing improvements mean that Opera's toolchain can now find the ideal solution even faster, further reducing the time and costs compared with physical design iteration cycles, and with no compromise in accuracy."
