Extremely Large Values in the Results. Can't visualize in ParaView but can visualize fine in Grasshopper #388

Closed shu-toz closed 5 years ago

shu-toz commented 5 years ago

Hi all,

I seem to be getting some really large values in the U-Magnitude. Even after checking and ensuring there are no points within the butterfly boundary elements.

The results seem to be shown in grasshopper with no problems however, upon closer inspection and auto scaling in paraview, they seem to be extremely high.

any insights would be great

Thanks

Maybe the time step in paraview is not the latest. Please check it

ymg2007 commented 5 years ago

I have ran your Atrium test file. It showed the similar result in Rhino and ParaView Velocity in Rhino and ParaView

And you didn't use any other settings than just opening the .foam file???

ymg2007 commented 5 years ago

Yeah, I just set a slice at Z=1m,and set the custom range 0-7m/s. image

When I tried to press rescale, nothing happens. The model still shows the smallest value (blue)

Would you be able to send me your .foam file? If I can visualise with your .foam file it might mean there's something wrong with my butterfly install

ymg2007 commented 5 years ago

The .foam file actually is an empty file. image Here is the .foam file. You can test it. Atrium_Test.zip

I tried to open the results, I could only see these, no U values... Screenshot_1

Ah turns out I was taking my slice source from the wrong source. I had the "InternalMesh" unticked. This was the correct source of information for the analysis.

I can confirm everything is working as it should.
