Displacement factor under 1?

[pablogil]

Hi,

I find sometimes that the Displacement minimum factor under "Results" task dialog, which is just 1, is too much to graphically show a small displacement... would it be possible to adjust the factor as, for instance, something like 0,001?

Thank you

By python easily …

- start FreeCAD
- Load Start WB
- Load 3D FEM example
- Activate analysis and run analysis
- run the following python code

Code: Select all

mesh_obj = App.ActiveDocument.getObject("Box_Mesh")
result_obj =  App.ActiveDocument.getObject("CalculiX_static_results")

mesh_obj.ViewObject.setNodeDisplacementByVectors(result_obj.NodeNumbers, result_obj.DisplacementVectors)
mesh_obj.ViewObject.applyDisplacement(0.1)

by GUI, not at the moment ... I may have a look at this.

more result scripting ...

Code: Select all

# set stress color
mesh_obj = App.ActiveDocument.getObject("Box_Mesh")
result_obj = App.ActiveDocument.getObject("CalculiX_static_results")
mesh_obj.ViewObject.setNodeColorByScalars(result_obj.NodeNumbers, result_obj.StressValues)

Code: Select all

# reset stress color
mesh_obj.ViewObject.NodeColor = {}
mesh_obj.ViewObject.ElementColor = {}
mesh_obj.ViewObject.setNodeColorByScalars()

small hint for the result scripting above ... use the result mesh not the analysis mesh. I may add the result scripting code to the wiki ...
