dump mesh/vtk face stresscomponents

Submitted by hansmannb on Wed, 03/05/2014 - 15:59

Hej guys,

i need for my further calculation the exact forces that take effect on my mesh cause by the granular.

I use the "dump mesh/vtk face stresscomponents" and get dumpfiles like this example:

>>> ...
CELL_DATA 168
VECTORS stress float
9960.909201 -132.616586 -27273.516696
0.000000 0.000000 0.000000
0.000000 0.000000 0.000000
-24516.993439 -42.767019 -5969.508000
-6635.700348 130.843939 -2145.554848
-4538.977929 415.493448 -1099.923739
... <<<

What are these values? Force? Pressure?
What unit is used?
Is there any other influence to consider?

What exactly ist the different to the "dump mesh/vtk face stress" command, where i get scalar pressure and shearstress?
Is there a possibility to get the direction of the shearstress?

Regards

Hi handmannb,

its basically fx/area, fy/area, fz/area. Seems this is not documented at the moment. I'll add it for the next release
