  Hi everyone!
  
  I am designing an doubly fed induction generator and I want to simulate it at software. I wrote dimensions to rmxport and it is working with no problem at there. But when I try to simulate it at 2d , I am getting an error which says could not preserve critical nodes . Can anyone help me about that problem?
  
  Thank you

  Hi ozturksa15,
  
  I had the same issue, but I'm not exactly sure what fixed it for me.
  When I deleted my inner region, my project ran, so there's that.
  
  Maybe try removing your inner region to see if that's causing the error?
