Part specific stress scale or hiding parts in stress plot...

John Tolman Dec 14, 2010 5:33 PM

Hi, I have a simulation with two parts. One of the parts, I am not interested in the stresses of, however the maximum stress is at the interface between the two parts. Is there a way to have a separate stress scale for each part, or to turn the scale off for one of the parts?

Alternatively, can I hide one of the parts in the plot while having it considered for the simulation still? Also, when analyzing one part, the yield stress has an arrow to it in the legend, I seem to recall. If I am only worried about one part in an assembly can I turn that back on, or since there are multiple materials it will hid the yield stress markers?

Thanks in advance.

Hi John,

In the Simulation Result Plot, RMB, Edit Definition->Advanced options-> uncheck the "Average results across boundary for parts" if you have different materials properties.

In the MODEL, hide the unwanted solid body(ies), but do not suppress them.

In the Simulation Plot, RMB Chart Options --> Check the "Show min/max range on shown parts only". The scale is then adapted to the shown part.

(note: you might have to show another plot, then come back to show that specific plot to be able to see the changes).

To check if a part of an assembly is included in the simulation or not, look in the Simulation/Parts section. All separate bodies and surfaces should be highlighted. A part (body/surface...) which is excluded should be grayed.

I also do not have the yield stress arrow(s) on the scale, when working with different materials.

  Thank you, that's exactly what I needed.

  What do you mean about the "average results when you have different materials"? Are you saying it is good practise to uncheck that option when multiple parts touch in an assembly that are made of different materials?

    I'll add, if it is good practice, I'd wonder when/why you would want to use the option. Even if they were the same material, why would you want to average across the interface?

      I suppose this averaging option could be useful in case you have several bodies of the same material, which are bonded. I would also like to know for which other case(s) this option is useful ?
      
      The problem is that the option is checked by default (Average Stress across boundaries is "ON"), AND it is hidden in the 'advanced options'. This had caused me big questions in the results of a thermoelastic study with incompatible mesh, 2 years ago.... After that issue, I always verify that this option is un-checked.
      
      This was reported already some time ago as SPR#519105 (Sensors always assume that "Average results across boundaries for parts" is ON), but I suppose it is not considered as a problem by Solidworks, as it has never been fixed.
