PREDICTED STEP (0.0000) LESS THAN 1.0000 WITH 0 VARIABLES AT BOUNDS. ITERATION STOPPED. I don’t know how to make changes; please help, experts!

The range of the variable does not meet the design requirements; I suggest you upload the bkp so that I can take a look at it for you

I have changed the variable range several times, but it hasn’t had much effect. The original computer has a problem; all the data is on it, and the simulation files cannot be transferred at the moment
