I proceeded as shown in the figure to check the flow rate on the inlet plane.

Through this process, the magnitude of the flow rate could be known.  
But I also want to know the direction of the flow rate.  
I’d appreciate it if you could tell me how to do this.

By default all fields should be interpolated in `ResampleWithDataSet` . Can you share the data or parts of them ?
