Possible Bug: thermal analysis convergence plots not consistently shown.

Hello all,

 

I'm running a thermal analysis - I have two studies (A and B) and while looking at the convergence plots for both I'm getting inconsistencies between the graphs and figures, which makes me question the reliability of the plot. Specifically the graphs for study B seem inconsistent and show different things when requested more than once.

Heat flux plot with correct graph unit and curve consistent with ACR.

Temperature plot selected and graph units are consistent - but convergence rate doesn't seem right vs plotted curve

 

Issue seems to be: 

  • When temperature plot is selected, heat flux graph is shown, and vice versa.
  • Graph and/or actual convergence rate does not update when the other plot is selected from the drop down. 
  • Convergence rate doesn't seem to update between plots for Study A (28.981% for both temp and flux which seems odd). 

The issue seems to be with the plots for Study B; those for Study A look like they're consistent.

Context:

  • Study B was cloned from A.
  • Only the applied temperature load and starting temperature adjusted to reflect different service conditions (A is 25C, B is 70C). 
  • Adaptive mesh refinement set at medium, medium mesh element size. 
  • Have done a brief search of forums/online for similar bugs without success. 
  • Fusion is up to date and otherwise behaving normally, using MacOS. 
  • Issue persists after logging out and in, restarting fusion and restarting machine. 

 

Anyone seen this before? If it's user error I'm very happy to be corrected.

@edward_bilsonFTL9L :  It it possible to get the files so that we can understand what is going on?
