Description
Creates a FEM fluid section element for aerodynamic and hydraulic networks
Use
- Click on or choose FEM → Fluid section for 1D flow from the top menu.
- Select Fluid type: Liquid, Gas or Open Channel
- Select Section type: Pipe Manning, Pipe Inlet etc.
- Enter Section type parameters.
- Select and add edge.
Limitations
- The contact constraint can only be applied to two faces.
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. Information on the card can be found here: http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node205.html
