I have been trying to simulate high voltage regulator LR8 on the MINDI software.

I first ran this circuit which came as is in the "examples" folder, and just changed the input to our need. It worked properly and gave a constant 5V output as expected.

We want a 60V/10V/18V output, however, so we tried manipulating the resistors R1 and R2 to get our required Vout= 60V (as stated by the formula in the data sheet of LR8) but the software refused to simulate this iteration. We tried several such iterations, but none worked.

Please guide me on how we can get our required output voltage of 60V/10V/18V.
