Same vector values in outdoor airflow analysis

Hi everyone,
I am getting the same results for the vectors at the end of the outdoor airflow analysis.

So, the color gradient is not formed since the values are same, and the vectors are not visualized at the end.

I am using last version of Butterfly. What could be the reason behind of this issue? Thanks!

Hi @mete
Because some test points or called probes is not in the domain, butterfly will return a very large value for them.
You should use legendpar to set the high bound to 5. And you will see the right result.

Hi @minggangyin

Thanks for your feedback. I have tried it, but it didn’t work out.

However I figured out the problem. The model was far away from the origin point in Rhino.

After moving it to the origin point, the results were shown up… eventhough there is still no color gradient for vectors…

i have some problem, how to fix it?

In my case I just moved the model to the origin point of Rhino, then it worked out.

the refinement region area of my object always in wrong side. I already move it into the origin point
