<div class=”x_elementToProof” data-olk-copy-source=”MessageBody”>I am sweeping frequency from 10k to 20MHz and cannot get simulation to run. Is there a simple video in the trianing forum you can recommend for trying to excite a coaxial fed loop antenna using lumped ports for the center conductor and shield? See errors below, and thank you for your help.<\/div><div class=”x_elementToProof” data-olk-copy-source=”MessageBody”> <\/div><div class=”x_elementToProof” data-olk-copy-source=”MessageBody”>Robb<\/div><div class=”x_elementToProof” data-olk-copy-source=”MessageBody”> <\/div><div class=”x_elementToProof” data-olk-copy-source=”MessageBody”>[info] GRPC server running on port: 50051.<\/div><div>  HFSSDesign1 (Terminal Network)<\/div><div>    [info] Parts Circle2 and Center_Conductor intersect.
