This test
lets you check space structure on elastic support, in the context of a
static case. You will use 1D mesh. This test is used to validate the discrete elastic
coupling. |

To Perform the Test:
The
SpaceStructure.CATAnalysis document presents a complete analysis of
this case, computed with a mesh formed of beam elements. Proceed as follow:
-
Open the CATAnalysis document.
-
Compute the case and generate an image called
Deformed mesh.
