Hello I think i´ve got the same problem....nI tried to simulate a coaxial cable but I could not get it working. It says attention required at the physics, but I get no warnings or specific tasks to repair.nThis model is surrounden by air, the body is just hidden.nsolid glas is used as dielctric material between the core and the outer conductornI tried a few different settings with the current:corss connection, source and return at both sides of the core, source and return with the core and the shell, and I also tried with a connection between the shell and the core at the end to close the circuit.nTwo Screenshots are added, I would appreciate your help very much.nI have read the topic above and also tried to reinstall AIM Discovery but it didn´t work.nOr is the problem, that Electronics Desktop is not included in the AIM student license?n
