Description
Creates a FEM fluid section element for pneumatic and hydraulic networks solved with CalculiX.
Usage
- There are several ways to invoke the command:
- Press the
Fluid Section for 1D Flow button.
- Select the Model → Element Geometry →
Fluid Section for 1D Flow option from the menu.
- Press the
- Select Fluid type: Liquid, Gas or Open Channel
- Select Section type: Pipe Manning, Pipe Inlet etc.

- Press the Add button. Select the edges. introduced in 1.1: To remove edges from the selection, press the Remove button.
Limitations
- The card only works with a 3 noded network element type. Information can be found here: http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node54.html
Notes
- An example of the set up of a hydraulic network can be found here: http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node13.html
- The *FLUID SECTION card is used to model fluid elements for 1D flow.
