Thank you for your response. As you pointed out correctly, using FR4 Epoxy as material of the traces was wrong. So I changed it to copper, and by that the ports were automatically detecting the available terminals. But now a new error is popping up : Port refinement, process hf3d error: Too few conductors were found on port p1. There should be one conductor for each terminal, with one additional reference conductor. Unintentional contact between conductors may cause this error. . (file attached)
I researched some more and found out that the error may be occurring if the line of integration doesn't touch both the conductors. Can you please suggest a solution for this ? (driven modal or driven terminal anyone).
