Learn how to use the 1D Plot functionality available inside the hydraulic, thermal hydraulic and Gas dynamics libraries
The animated 1D-Plot feature is only available inside the CFD-1D pipe submodels. You can use this feature in order to animate the internal nodes of the CFD-1D lines in the following libraries:
In the hydraulic library you can animate the pressure and flow rate of the internal nodes.
In the thermal hydraulic library, you can animate the nodes’ internal pressure, temperature, mass and volumetric flow rate.
In the CFD-1D Gas Dynamics library you can animate the internal static & total pressures, static & total temperatures, density, velocity, mass flow rate and Mach number.
This feature allows you to animate the value of the selected variables among the simulation time and it can be very useful to analyze some dynamic fluid phenomena such as the water hammer effect. In order to create an animated 1D-Plot:
You need to use CFD-1D pipe submodels available in the hydraulic, thermal hydraulic or CFD-1D Gas Dynamic libraries
Then you need to have internal nodes available inside the pipe. Every library has a specific parameterization for setting the number of internal nodes and some of them special setting for the 1D-Plot:
In the hydraulic library:
There is no special setting for using the 1D-Plot feature. The only thing, that we could parametrize the number of nodes, that we would like to have inside the pipe, and this is done directly in the pipe submodel. The only important thing to know is that the position of the internal nodes always goes from Port 1 to Port 2. To create the 1D-Plot you just need to right click on the variable, which you would like to analyze and select Plot > 1D:
In the thermal hydraulic library:
In the parameters of the CFD-1D pipe submodel, you can select if you want to activate the 1D plot functionality, how many points/nodes, you would like to have in the plot and the direction of these points inside the pipe (from Port 1 to Port 2 or the other way around).
To create the plot, it is the same process as in the hydraulic library, just right click on the variable, you would like to plot and select Plot > 1D:
In the CFD-1D Gas Dynamic library:
Same parametrization as in the case of thermal hydraulic. You can also choose, if you want to activate the 1D plot functionality, how many points/nodes, you would like to have, and the direction of these nodes inside the pipe. Then go to the post-processing tool (plot 1D), right click on the desired variable and select Plot > 1D:
