Simulate Early, Simulate Often... In Rhino
I'm writing to you as it seems to me that something is wrong in the presentation of the value of the value of the principal strain and stress.
In a point of the model of my simulation I've found the following values :
stressxx : 0.161759
stressxy : -0.164002
stressxz : -0.306937
stressyy : 328.186
stressyz : 328.75
stresszz : 328.74
Max principal stress :657.213
Mid principal stress: 0.183215
Min principal stress: -0.309
Max principal strain : 0.0158622
Mid principal strain : -0.00313948
Min principal strain : -0.00948482
I've performed some calculations in Matlab and in my opinion the value of the strain should have been
Max principal strain : 0.0095
Mid principal strain : -0.0031
Min principal strain : -0.0031
Here attached are my calculations with matlab.
Maybe there's something wrong in my calculations , but I can't imagine where.
I would really appreciate a hint
Thank you for discovering this. It appears that a bug crept into the WIP code for the computation of the component strains, and thus the component stresses and principal stresses and strains. The bug appears to be on the visualization/querying side of things rather than inside the core simulation code.
Once we have it fixed, we will post a new WIP/Beta and let everyone know.
Thank you for your patience as we sort this out.
