I never did post the updated version with CST so here it is: Which is better in discontinuously hfss or cstĪ couple of years ago I posted stripline benchmark results to compare 2.5D and 3D tools.
If you skip to the last page in the spreadsheet you will see a comparison between HFSS and CST (both FD and TD solvers). The error for HFSS looks good at 100 seconds, however as mesh density (and analysis time) increase the error diverges.
The error curves for the CST solvers are smooth and monotonically decreasing. This is only one type of problem so you can't conclude one is better than the other. I prefer CST (we recently purchased it) since I can choose between TD and FD solvers. When evaluating CST for purchase I gave them a patch antenna design that I simulated in HFSS and measured.
All three agreed well but the CST TD solver was faster with less memory I don't have specific numbers. Now that I have access to both I want to try a log-periodic dipole array I designed in HFSS and measured. Since it's broadband it will make a good comparison between FD and TD solvers.Īlong the lines of the previous post, CST gives you more control over meshing. Thats right, all the lists of alternatives are crowd-sourced, and thats what makes the data powerful and relevant.It's easier to do finer/variable meshing for particular parts of the model than in HFSS. This list contains a total of apps similar to CST MICROWAVE STUDIO. VORPAL enables researchers to simulate complex physical phenomena in less time and at a much lower cost than empirically testing process changes for plasma and vapor.įeel free to add any alternative that you know of, or ask your friends on Twitter or Facebook if they can help out.įilter by license to discover only free or Open Source alternatives.
