maybe histogram without dice rolling for identical domains?

+Further tension models:
+ Exponential rising tension (ERT)
+ f = E0 / alpha ( e^(alpha x) - 1 )
+ Enhanced WLC (with stretching)
+ f = kB T/p { 1/4 [1/(1-x/L-f/K)² - 1] + x/L - f/K }
+ Enhanced FJC (with stretching)
+ x/L = [coth(Lk f/ kB T)- kB T/Lk f](1+f/K)
