Simply set INFO(9) for that component to 1 and it will be called at least
once per timestep - even if it's inputs have not changed between
timesteps.  It will however not be called at every iteration within
a timestep and I cannot foresee a reason why you would need this
feature.  By definition, if the inputs are not changing, and TIME is
not changing then the OUTPUTS cannot change!  If you are worried
about watching a small value that is an input (like humidity ratio) and
small changes are not caught by the tolerances check, then simply
multiply the output value that is connected to this input by 1000 with an
equation and divide by 1000 within your code.
