I have designed a dual band notched UWB antenna using CSRR stacked between substrate and feed line. While simulating using HFSS, an error message " Port refinement, process hf3d: Too many conductors touch lumped port '1'.Consider splitting the port into multiple lumped ports" and "Simulation completed with execution error on server: Local Machine " persistently comes.
Would you mind to give a possible solution to fix it soon?
Thank you in advance!!!

Hope this will solve your problem.
When port is improperly designed such error will come.
When you are going to use lumped port then only to conductor should be there from where the vector line starts and ends in other end. If you are consider thicken sheets or thick conducting wires then such issue may arise.
Here you have to give the excitation line only up to one edge of the thicken sheet.
After avoiding this situation you can able to run the simulation smoothly.
