Dev,<br>
Adding thermal capacitance to the model itself would involve
changing the source code and asking for some additional parameters
so that you would be able to solve the first order differential
equation that describes the behavior. You'd need a Fortran compiler
in order to modify, recompile, and relink the code into a modified
component. You would also need to change the proforma.<br>
<br>
Another method that you could use to accomplish something like the
same effect without modifying the source code would be to put a tank
model (Type534 ideally) either directly upstream or directly
downstream of the boiler. This would at least account for the
thermal capacitance and standby losses of the liquid volume
associated with the boiler.<br>
