#The contact stiffness should be 10 times the young's modulus of the material for hard contact. The higher the value for contact stiffness, the harder the contact between surfaces.
 
#The slave face is the face which penetrates into the master face, and therefore experiences more deformation.
 
#The *CONTACT PAIR card is used for modeling contact in CalculiX. The constraint uses Face-to-Face penalty contact and the contact formulation is explained in detail at http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node112.html

Description

Creates a FEM fluid section element for aerodynamic and hydraulic networks

How to use

  1. Click on FEM ElementFluid1D.png or choose ModelFEM ElementFluid1D.png Fluid section for 1D flow from the top menu.
  2. Select Fluid type: Liquid, Gas or Open Channel
  3. Select Section type: Pipe Manning, Pipe Inlet etc.
  4. Enter Section type parameters.
  5. Select and add edge.

Limitations

  1. 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

  1. 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
  2. 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
