Optimization in Feko

Recommended Posts

I have put an antenna on an aircraft and I calculated its far Field. Now I want to optimize the antenna by moving it in one direction (e.g along x-axis) and I want to see where the gain is maximum?

Hello ben,

 

This sounds like a very simple optimisation for FEKO. What is the problem? Or where are you getting stuck? I would suggest that you first try a simple optimisation so that you are familiar with the interface. There are a few examples and also a Getting started example for optimisation.

Did you work through and understand the Getting started example?

The optimisation process runs many variations and evaluates each run based on the defined optimisation goal. How the goal function evolves is an output parameter that can be displayed in POSTFEKO. The result of the optimisation is a model with the optimum model parameters. The optimum model is stored with a _optimum added to the model name.

 

From the comment, it sounds like you don't really want to do an optimisation, but rather a parameter sweep. FEKO ships with a parameter sweep script. It has two parts. The first part is run in CADFEKO and then once the solver has been run, the POSTFEKO part of the parameter sweep script is used to combine the results. Is this what you are trying to do?

feko does not have a parametric sweep only optimization ,, in postfeko save the curve that you want to observe by right click and store copy ,, keep postfeko open , go to cadfeko and the change the value of parameters that you want to study , after the run complete you will see tow curves in postfeko the new one and the stored one
