Exactly!

Itchy is right as far as my situation is concerned. Hoop stress legend did show up but the color plots in graphical area are NONE even if i zoom to like 10000 times to the areas (which i know are stressed enough).

I have Caesar 5.10 and after installing this to many many PCs i get the same result.

I have been working for 5 years in AutoPipe (Bentley's Piping Stress program) and believe me when you have a huge piping network to analyze these color plots are just the right thing to catch overstressed points more accurately and timely.

I have been trying hard to solve this problem in Caesar 5.10 but with Zero results so far even after googling this problem alot.

Can somebody with experience or someone from COADE would like to explain the problem in our system / graphics card/driver etc which might be causing that problem ?

One more thing! I just downloaded the Demo version of Caesar 5.20 and to my surprise i can see Color stress plots in graphical area for every model/sample i made or opened.
