Is it possible to calculate and hold a value constant during the Simulink calculation

Is it possible to calculate a value somewhere during a simulink simulation and use it from that point on as a constant in a calculation. I would use this in a IF action subsystem (or maybe While or For loop) where at a certain condition a value should be calculated and from that point on used in a calculation as a constant.

Do you have some example in block diagram. I am trying to calculate a value, during simulation then use this value as input during same simulation, but his value does nedd to be updated for the whole time, just for a portion of it.

Put the calculation inside a triggered subsystem and make the output of the system the desired calculated value. Trigger the subsystem when you want to calculate the value.
