Description
Creates a FEM fluid section element for pneumatic and hydraulic networks
Usage
- There are several ways to invoke the command:
- Press the
FEM ElementFluid1D 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.
- Enter Section type parameters.
- Select and add edge.
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. Information on the card can be found here: http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node205.html
