Dear Parisa,

To start working with A-solver in CST, here are some initial steps you can follow:

Regarding your question about whether A-solver can generate 3D far-field results, the answer is yes. A-solver is designed to generate accurate far-field results for electromagnetic devices, including antennas. You can view the far-field results in 3D using the "Far-Field" tab in CST.

It's important to note that the accuracy of the far-field results depends on several factors, including the quality of the mesh and the simulation setup. Therefore, it's essential to carefully set up and validate the simulation before relying on the results.

Thanks Miguel.

I could run a simulation with A solver but it doesn’t support lossy dielectrics which was important in my simulation
