3. Modeling A#
3.1. Characteristics of modeling#
The bars \(1-2\), \(2-3\), \(3-4\), and \(4-1\) are each modeled by 1 element BARRE.
The cables are each modelled by a CABLE element.
3.2. Characteristics of the mesh#
So there are 4 elements BARRE and 2 elements CABLE.
3.3. Quantities tested and results of modeling A#
We start by testing the \(N\) tensile forces in cables and bars:
Identification |
Reference |
Tolerance |
\(N\) in the \(3-4\) bar at NUME_ORDRE =2 |
-1000, 0 |
0.03% |
\(N\) in cable \(1-3\) to NUME_ORDRE =2 |
-1414.2 |
0.03% |
\(N\) in the \(1-2\) bar at NUME_ORDRE =2 |
0 |
1.0E -3% |
\(N\) in the \(2-3\) bar at NUME_ORDRE =2 |
0 |
1.0E -3% |
\(N\) in the \(4-1\) bar at NUME_ORDRE =2 |
0 |
1.0E -3% |
\(N\) in cable \(4-2\) to NUME_ORDRE =2 |
0 |
1.0E -3% |
3.3.1. Other values tested#
We also test the nodal force at the N3 node, which must be equal to the external force applied (i.e. \(\mathrm{1000N}\) according to DX):
Identification |
Reference |
Tolerance |
FORC_NODA, direction DX, at node N3 and at NUME_ORDRE =2 |
-1000, 0 |
0.03% |
The parameters of the result data structure are also tested:
