[Gmsh] plot a vector field in Gmsh

[Marios Papadopoulos]

Hello Christophe and Jean-Francois,

I'm a PhD candidate student and i'm using your Gmsh enviroment to pre & post
processing my FEA data. Until now, i managed to plot a scalar field
(X-component of the Displacement) in a simple beam bending example like this
example:*
*

$MeshFormat
2.1 0 8
$EndMeshFormat
$Nodes
6                      *six mesh nodes:*
1 0.0 0.0 0.0          *  node #1: coordinates (0.0, 0.0, 0.0)*
2 1.0 0.0 0.0          *  node #2: coordinates (1.0, 0.0, 0.0)*
3 1.0 1.0 0.0          *  etc.*
4 0.0 1.0 0.0
5 2.0 0.0 0.0
6 2.0 1.0 0.0
$EndNodes
$Elements
2                      *two elements:*
1 3 2 99 2 1 2 3 4     *  quad #1: type 3, physical 99, elementary 2,
nodes 1 2 3 4*
2 3 2 99 2 2 5 6 3     *  quad #2: type 3, physical 99, elementary 2,
nodes 2 5 6 3*
$EndElements
$NodeData
1                      *one string tag:*
"A scalar view"        *  the name of the view ("A scalar view")*
1                      *one real tag:*
0.0                    *  the time value (0.0)*
3                      *three integer tags:*
0                      *  the time step (0; time steps always start at 0)*
1                      *  1-component (scalar) field*
6                      *  six associated nodal values*
1 0.0                  *value associated with node #1 (0.0)*
2 0.1                  *value associated with node #2 (0.1)*
3 0.2                  *etc.*
4 0.0
5 0.2
6 0.4
$EndNodeData



*I want to write X, Y, Z Components of Displacement Field in the shame
.msh file and plot them to Gmsh. How i can do this?
*

Thank you in advance!

Marios
