 == Introduction
 
 A Vierendeel truss is a lightweight deep beam or girder structural concept.
 The goal of this exercise is to determine the deformation and stress state of the aluminium Vierendeel truss shown below, in particular the maximum stress around the lightening holes.
 
+== Running the case
+
+The command line to run this case is
+
+
+[[command-line2D]]
+[source,sh]

+feelpp_toolbox_solid --config-file Plate.cfg

+NOTE: The report of the execution of the command above is available xref:vierendeel-truss/solid-informations.adoc[here].
