This post presents some useful tricks to get started with Salome-Meca Pavavis module (or Paraview). Let’s assume you already have followed this tutorial or by another way, got a Code_Aster rmed result file open in Paravis.
Deformed Shape
As shown in previous posts, it is possible to show the displacement field as a magnitude scalar map. But to show the deformed shape, one needs to create a new display data entry. To do so, select the rmed view in the pipeline browser, then in the main menu Filters -> Common -> Wrap By Vector.
A new wrapped entry appears in the pipeline browser. Click on Apply button to display the wrapped field. To amplify the deformed shape, use the Scale Factor slider-button and click Apply button again to validate the modifications.
Nodal Element fields ELNO
ELNO corresponds to a field stored by element, one value for each element node. These fields cannot be displayed directly, as it is shown in this picture:
A new entry should be created. To do so, select the rmed view in the pipeline browser, then in the main menu Filters -> Mechanics -> ELNO field To Surface.
A new Surface view appears in the pipeline browser. Click on Apply button to display this field. It should be now possible to access ELNO fields. Let’s select SIEQ_ELNO,
and choose Coloring by VMIS, to display equivalent von Mises stress field.
Gauss point Element fields ELGA
ELGA corresponds to a field stored by element, one value for each element Gauss point. As it is used at resolution time, SIEF_ELGA stress field is always present in a Code_Aster non-linear result, and thus more accurate that post-processed SIEF_ELNO or SIEF_NODE that may lead to interpolation smoothing side effects.
But as ELNO, ELGA fields cannot be displayed directly and a new entry should be created. To do so, select again the rmed original view in the pipeline browser, then in the main menu Filter -> Mechanics -> ELGA field To Point Sprite.
A new Point representation view appears in the pipeline browser. Click on Apply button. It should be now possible to access SIEF_ELGA field.
We can for example display SIXX, corresponding to the stress tensor normal component in direction X.
Point size can be adjusted after switching to representation Points.
Conclusion
Post-processing Filters menu is one of the most important feature to begin with Salome-Meca Paravis module. Considering that Paravis module is an embedded Paraview in Salome-Meca, one can have a look to Paraview wiki for more advanced features.
