"I'm seeing the same thing as Nick.
Multiple solids, analysed one at a time, but frequent crashing.
I crash either after exitin the SNS box and saving the analysis data, or saving the Rhino file.
I also notice some mix-up with my torque axii :…"

Crash when pressing done with two solved items

G'day,I have a file that keeps crashing. It has a number of closed polysurfaces in it but I have analysed only two with SnS. It crashes after pressing the Done button on the second analysis.Is SnS…Continue

Changing Units

G'day,I have a model that was originally built and analysed accidentally using metres instead of millimetres. The units have been changed and the size is now correct, however SnS thinks it is still…Continue

Wheel Mouse Zoom

I have recently discovered that zooming with the wheel mouse does not work with SnS running. Maybe it has never worked but I only just noticed. Either way it would be nice to get this fixed if there…Continue

"In finite element analysis, stresses are computed from displacement/deflections and are not in strict equilibrium with the applied loads. Internal forces are computed (integrated) from stresses and are not equal to reaction forces, but…"

"Michael,
Now it's time to hard-code this in Scan and Solve :)
I notice a discrepancy of 111 N (5%) between the 2000 N and the internal shear forces in your example.
What do you think accounts for this ?
Cheers,

"I've added an example script to the documentation for SnSScript that computes (approximately) internal forces by integrating component stresses in the model. The script and documentation can be found at this link.

"Yes, you can analyze more than one polysurface in a single Rhino document, with one caveat: Do not attempt to have more than one session of SnS open at a time. Scan&Solve won't currently prevent you doing this, but…"

"Using SnS for composite parts is dubious at best. The quote below is an understatement. The best you could hope for is being able to analyse chopped strand mat parts since they are somewhat isotropic, and even then it is a bit dubious. A cored…"

"We are not working on reaction forces yet, but you could compute the resultant forces on any restraint surface by integrating the component stresses over them, using SnSScript. These resultant forces approximate the reaction forces, but are…"

First of all. Hello everybody, since this is my first message in the forum. FYI - I use Scan&Solve to check my hand calculations on structures used for marine transportation.Reaction forces would be really interesting for me since they are…"

"Reactions would also be very useful to me.
It could allow me to know the traction in the anchor bolts of a steel structure baseplate, along with the check of the baseplate itself.

With Version 1.5, we introduced Unicode encoded reports that allow customization of the templates into languages other than English. It appears a bug crept in at the same time that outputs into the report the full file paths to the…"

Nick replied to Nick's discussion 'Changing Units'
"Thanks Michael. Since this is probably a rare occurrence it isn't necessary to have a feature for changing units.
Maybe a units item in the results tab and displaying the reaction forces will be enough to alert users to any inconsistencies. I…"
