Hi Barry, hi mohamedzaid786,
Thank you for your advices in regard to meshing and wind tunnel settings, it das been extremely helpful.
I was testing some different meshing options and have been in contact with the paraview support, thats why it has been a little bit silent from my side during the last days.
I know that I still need to work on the meshing and wil also optimizes wind tunnel settings, however my problem is (I think) in regard to point data and cell date:
In paraview there are two different options to visualize windspeed, one uses cell data, the other own point data. When I use cell data, the result seems to be fine (even with a rough mesh).
However, If I want to visualize point data, there are artifacts between buildings and open space and the transition between the base mesh and the first refinement area shows the same problem.
Also, if you compare the screeshots fom CellData and PointData the inward wind flow for point data seems to be between 0 and 5 m/s while cell data shows 10 m/s.
To me, the cell data result looks good, but celldata dont, as it shows inward wind flow (left hand side) with nearly 0s/m, instead of 10m/s.
Do you have any ideas, why the results are so different?
I was wondering, how cell data is generated in simscale and how I can change settings, in order to get a correct result.
Thank you very much in advance!
