The purpose of the dynamic module is to simulate changes in input temperatures and loads as a function of time.
By using the dynamic module, the user can study how temperature fronts prepare themselves in the pipe network as a function of the time.
The time scale for the dynamic calculation extends from minutes to 24 hours.
Water hammer cannot be simulated using the dynamic calculations due to the time scale for water hammer, normally less than one tenth of a second.
The results are presented in tables, graphs and plots.
Simulation is carried out as a series of stationary calculations separated by a user-identified time interval where the results of the preceding time step adjusted by time-dependent factors constitute input data to the next time step calculation.
To change the load in different parts of the network with time, the nodes can be linked to one of ten potential categories. For every category, the load can be scaled using a time-dependent factor. The supply temperature and production price for the production plants can be changed during the day in a similar way.
