Spring construction
The spring construction consists of two rectangular plates with four spring leaves between them. The springs are symmetrical with respect to forces in x, y and z directions.
* 
The outer rectangular plate together with the spring leaves consists of the same face. The inner rectangulare plate is a different face and has set different wall thickness in the C-A command file. In the picture at the right hand side the transition between the two part is clearly visible with the straight mesh line.
In the python script the geometry and the mesh are defined: Media:kw_spring3.zip
In this file you can see how the geometry is defined by:
- points to define the inner and outer rectangles
- points to define the springs
- lines between these points to define inner and outer rectangle and springs
- lines and wire to define the dividing between springs and inner rectangle
- partitioning of the outer rectangle and springs and inner rectangle
- grouping of the various elements:
- >> faces: outer rectangle and springs shout, inner rectangle shin
- >> lines for boundary conditions and forces: inedge, outedge
- >> nodes: node1 (N1), node13 (N1 and N3) and node4 (N1, N2, N3 and N4)
