Could anyone please let me know if it is possible to force a unit to be
called at every iteration in a time step irrespective of weather its inputs
have converged.


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.
