[Wien] Calculation of Ueff

[karima Physique]

Thank you for your answer,

The two calculations converged but with more than 100 iteration (bad
convergence)
 But in the paper presented by G. K. H. Madsen and P. Novak, they used a
single point and a value of RKmax = 5,
Can I force the calculation to 1000 Point for example and RKmax = 8.
