Hello,
More or less that’s the way.
- select ‘hidden lines’ in display style.
- open the ‘mesh deformation window’ under menu ‘windows’-‘Deform mesh’.
- select ‘deformation’ with the result you want to use in the ‘Main Geometry’
section. selec ‘Original’ in the ‘Reference geometry’ of the same window.
- change the color of the mesh.
In ‘figure0.png’ is an example and in ‘window0.gif’ the options selected in the
‘deform mesh’ window:
when the file was read, the mesh colour was the dark yellow. After doing
steps 1., 2., 3., on the 4. step, the colour was changed to red.
As the ‘main geomtry’ is deformed, up now all the visualization changes will be
made to the deformed meshes: view results, colour changes, display styles, …
You can also do the other way:
set the ‘main geomtry’ to original and deform the ‘reference geometry’.
Then, all the changes will be made over the original mesh.
— a brief explanation of the ‘deform mesh’ window —
there are three ways to work with deformations
1· show the original and the deformed mesh and viewing
the results over the DEFORMED mesh and change its colour,
2· show the original and the deformed mesh and viewing
the results over the ORIGINAL mesh and change its colour, and
3· show the deformations of two differemt steps and viewing
the results over one of them and change its colour.
open the ‘mesh deformation’ windows, under menu ‘windows’-‘Deform mesh’.
there are two parts:
· Main geometry: this name referes to the mesh that you ar using normally,
were you are viewing the result and which you can change its colours, etc.
· Reference geometry: this refers to a ‘copy of the mesh’, just for viewing purposes.
Only using this window you are able to modify this ‘copy’. So the changes
you done to the meshes ( colour changes, display style, …) are fixed for this
‘copy’. No results visualization is done over tis ‘copy’. It is like a photo.
for instance:
for ‘figure1.png’:
- display style to ‘boundaries’
- deform mesh acording to ‘window1.gif’: deform the mesh so that i can draw results
over the deformed mesh, and set the ‘reference geometry’ to ‘original’ to compare
with the deformed.
- display ‘contour fill’ of desplacements.
for ‘figure2.png’:
- display style to ‘body’ and transparent
- leave the ‘main geometry’ to original, so that i can draw vectors over it, and
deform the ‘reference geometry’ just to view the deformation. Look at ‘window2.gif’
- change the display style to ‘boundaries’, tornunig the transparency off
- display vectors ‘Nodal Stress’
You can also compare two deformations: ‘figure3.png’:
- display style to ‘body’
- in the first section of the ‘deformation window’, ‘window3.gif’: the ‘main geometry’
is deformed using the ‘DESPLACEMENTS’ of Step 4 (LOAD ANALYSIS), and
in the second section, the ‘reference geometry’ is deformed according to the
‘DESPLACEMENTS’ of Step 2. Note that the factor is de same: 120 to make a good
comparation.
- Both representations have the same color: dark yellow. now its time to change the
color: in ‘display style’ window we change the color of the mesh to red. As
‘figure3.png’ shows, the meshes which we deformed in the ‘main geomtry’ section are
the ones with the colour changed, not the ones in the ‘reference geometry’ section.
Hope it helps,
miguel

Hello,
I’m postprocessing some results and I want to superimpose the deformed mesh
over the original configuration.
I want to use a different color for deformed and undeformed mesh in hidden
lines view mode.
At present, I set a color for the volume set (in Windows - View style),
then I change it with Options-Change color-Volume sets-myset.
Then I choose viewing deformed mesh in Windows-Deform mesh
Sometimes it works.
Which is the best way to do it? (I use GiD 6.2.0b.)
Thanks in advance
