Question submitted by user via email:

Is there a way to display the MOS in elements that have RBE elements connected to them? When I view them in HyperSizer, the elements are greyed out for the elements  where RBE2 elements are connected.

What kind of elements are you looking at that are greyed out?  HyperSizer should ignore RBE elements completely and they should not affect the results for CQUAD, CBAR, CTRI, or CROD elements at all.

The elements are CQUAD4 elements.  It seems like always the elements that are connected to RBE elements are grayed out. I also checked different color palettes which gives the range of margin of safety from min to max.

It appears that the elements that are showing up with no results actually have zero (or very nearly zero, like 1.0E-11) loads for all load cases.  HyperSizer has a check that when it encounters an element with no loads or thermal gradients, it skips over that element.  The margin of safety would be infinite if it were calculated.  That is why those elements are showing up as having no results.  Is this a problem for you?  I can talk to Craig about what should be shown for those elements, but in reality, the elements do have an infinite margin of safety, so them showing up as “no data” seems appropriate.

Let me know if this makes sense to you or if you need more info.
