if i have a simulink model and the output of low pass filter is sin signal with certain frequency if i want to know this frequency and display it on a screen what should i do? remark simulation model time is (inf.)

I would output the signal to the workspace and calculate the frequency from within Matlab; here is an example approach. You could use Matlab to start your simulation too using the sim command, and afterward plot the spectrum that you calculate.

my simulink model time is inf

how i can import data from simulink in inf tim?

You could decide how much time you would need to get a good estimate of the frequency (for example, 30 periods of a 10-second sine wave would be 300 seconds), then put an event listener (http://www.mathworks.com/help/toolbox/simulink/slref/add_exec_event_listener.html) in your model that would output the results to the workspace at 300 seconds.
