Justin gave more information on the question:
Jan,
Link to google drive with files:
https://drive.google.com/drive/folders/1ygHckMnSksTSuMzfdsxSRS5pFaQP4-mC?usp=sharing
In the folder:
- Three MWE (Original, increase 5% and minus 5% of density of spheres):
Basically, there all the exact same
- Three CAD files needed to run the models: block_test.mesh, small_base.mesh,
and 1mm_heightchecker.mesh
- block_test.mesh, is not the object I'm using for my research. Didn't
want to share everything with the world, yet. Perhaps, I can share the actual
object over email.
- Three plots:
- Sensitivity_Testing.png is the plot that goes with the included
models (i.e., using block_test.mesh). Admittedly the results were better than I
expected. But two models still started negative? And the original model had a
higher torque than the plus 5% density model.
- density_Sensitivity_Testing.png - Results from a model exactly the
same as the MWE, except used my actual object (i.e., not block_test.mesh).
- density_Sensitivity_Testing_2r.png - Results from same model as
above, except sphere radius was reduced to 2 mm and sphere count increased by
eight times.
Problems:
1) All plots have runs that start negative, which is not intuitive. I feel they
should all start at zero (or close to it).
2) Sometimes results can be radically different (e.g.,
density_Sensitivity_Testing.png)
3) Even when not radically different, the results doesn't make inherit sense.
I.e., spheres with less density can create more torque on the object than
spheres with a lower density.
As always, thanks for the help,
Justin
