I am 200% certain that these questions arise because Wien2k is not giving
you the result you think it should. I am 2000% certain it is not converging
because you have made mistakes. You must check that you have a valid
calculation.

Do not do this.

(2) Whether it will be accurate?

Not a relevant question.

(3) If we do not get force convergence with PORT should we go for NEWT/NEW1?

No. If you do not get force convergence with PORT it means that you have
invalid patameter
