Solver error while following tutorial video

Hello community,

I am learning to use COMSOL by following tutorial videos from the archive. I am precisely referring to the lecture titled "Introduction to Modeling Electromagnetic Coils in 3D Using COMSOL". In the very first video we model a 1.5 turns coil, set a 1 A current through it and then solve for the magnetic field. I am doing everything exactly like in the video but I am getting an error during the computation of the solutions. The error reads:

"Failed to evaluate initial residual for segregated step 1. Numeric Coil 1 (coil 1) not solved for. Solve it in a Coil Geometry Analysis step."

The Coil Geometry Analysis step doesn't have many options, I tried specified Input and Output for the electric current and also only Input with same results. I am using COMSOL 6.0 btw.

What am I doing wrong? any help will be appreciated.

Kind regards,

Agustin
