Hi
I have a very simple question, As shown below in the figure density contour ranges from 2400 to 1200. I have assign a UDF with  two values of 2400 and 1200 kg/m3. Why it shows the other contours. How ANSYS calculate this and did it have effect on the solution because my velocity and other rheological properties depends on these cells position and density.
why not only two vales???

 

Kind regards

You're looking at the smoothed results. Replot with node values off.

Hi

please can you elaborate this?

[Rob]

You've set two layers of cells to be the lower value. The rest of the domain is the higher value.  When you display contours you smooth the result to give a "nicer" image: otherwise you get the cell centre value. Turning off the node values will give the cell centre value but may also give a very tessellated result if the mesh is too coarse.

Hi,
The nodes values could be turn off in the meshing console or also during the pre-processing.

No, you can turn off node values in the Contour panel: you'll then display the cell centre value.
