I am simulating turbulent flow over buildings. After the computation finished, I want to see the numerical values of the 'wall lift-off in viscouse units' on the ground. One only thing that I can do, however, is that the 3D plot of 'wall lift-off in viscouse units' for all walls, which include the top wall, side walls. The vaules on the top and side walls are very much large (e.g. 1000). I want to examine if their numerical values all over the ground between 30-100.

Please suggest me how to do this.


Thank you.

Hi

you can dedouble your data set and add a selection list to it (to define only a few domains or boundaries or ...), then point the plot view to this new data set, or you add a filter node to your plot node and define a bolean condition over coordinates or domain id or ...

If you want to restrict the data or the display colors to a predefined range, you have this option in the lower plot nodes under one of the last tabs, you can also select line type, markers, position of markers, legend ...

Good luck
