step size = (Tmax-Tmin)/50
my question is why it should divided by 50?

It is formula for step size,step size is used to solve the simulink model.step size = (Tmax-Tmin)/50, in this formula why 50 is taken to calculate the step size.

Without more specific context of your system it is still impossible to give you a more meaningful answer. Apparently the units that Tmin and Tmax are in are 50 times larger than the step size of the model, or there should be 50 steps, or any other reason.

HI SK, Let say you have a function f (t) and you want to plot it between t = Tmin and Tmax, in matlab, you have to choose a step size to do so. The step size is defined as delta = (Tmax-Tmin)/(N-1), This is exactly what the function linspace does. The following are equivalent :
N = 51;
stepsize = (Tmax-Tmin)/50;
t = Tmin:stepsize:Tmax;
t = linspace (Tmin, Tmax, 50);
