Study 1 error

Please login with a confirmed email address before reporting spam

Hello,
I want to ask some questions. I can try make an example e-core magnet design. There is an error in the Study 1 section. When I right click the Study 1 and select show default solver, an error happens : " The DAE is structurally incostistent. Variables:2 Equations:1 Error in automatic sequence generation. "
I thinking one of the reason of the error is the External I Vs. U 2 I enter only p label parameter for 3, there is no n label parameter in the example.
The other problem, in the Gauge Fixing for A-Field 1 section, there is no "Constrain variable in at least one point" check box. I can not found it. Please can somebody help me?
