Hi,

I did fatigue analysis in nCode DesignLife. I create 'Named Selection', and I can see the parts. When I want to see fatigue analysis result on these parts, half of the parts does not have any result. I think, this is bug.

Are results missing or are they out-of-range?  For example, if the calculated stress range is greater than the UTS, DesignLife will not calculate fatigue damage, becasue is assumed that the component will fail with 1 cycle of loading.

I can't see the result like this area. Fatigue results of some surfaces of the part are not visible. It looks like it's torn apart.

Are the results for that area available in the DataValueDisplay table?  If so, then it is a graphics issue.  If not, then the solver did not calculate the results in that region.  Can you file a support case and provide the model?  If so, we can dig into deeper.

The solver did not calculate the results. This image is an example. I did an analysis at university, so I'm so sorry, I cannot share the project.

Hi sir,

Is there any method to solve this problem? I could not find any information on the internet.

[danielshaw]

Sorry, but I cannot debug this behavior without more information.  It might be a bug, but I doubt it.  What release are you using?  Did you try running the fatigue analysis using the Mechanical Add-On?

[danielshaw]

If you are having difficulty with DesignLife graphics, you could plot the DesignLife results inside Mechanical.

Thank you so much
