Ansys 17
 

I have ran 5 very similar simulations in Ansys 17 fluent.
4 worked well and I have obtained the results.
One however has been a pain from the start. Ranging from Meshing problems to floating points etc.
I sorted all the above and it happily ran 10,000 iterations.
All 5 displayed 600-630 N pressure as expected.
In post processing 4 happily showed the pressure contours and the streamlines I set up.
Apart from one. I verified all parameters and setups were identical.
Yet, the last one will only show one single solid flat colour in CONTOURS.
I tried many adaptions but still no changes.
So, I re-run the 10000 iterations.
Again, when selecting contours (150 or even 10 contours) only one is displayed, in one single blue colour.
I do not understand what is wrong.
Any advice ?
