lua scripting for antenna coupling analysis in Altair FEKO Posted October 4, 2018 · Report reply Hi tejaswi, I think you need to be more precise in what you're asking. What do you mean with "add an source"? Do you want to add results to a given graph? Maybe an example would be helpful. Please note, this is very off-topic, maybe you want to create a new ticket regarding this scripting question?
