Dear Code_Saturne users/developers,

I ran the fluid_alone case of v4.0.0-rc2 example 4-2Ddisks without modification
(/code_saturne-4.0.0-rc2/examples/4-2Ddisks/case1/fluid/fluid_3disks_alone.xml)
and view the result on Salome 6.6.0 ParaViS.

I got a flow (attached) that does not look anything like what shown in the instruction document. And, the Glyph plot does not have Glyph magnitude option in the "Color by" section to color the velocity vectors. Any ideas? All I did was just running the example case without modification. I may have postporocessed it wrong. Thanks.

Hello,

Under ParaView, to get glyphs right, you need to apply the "cell data to point data" or "cell centers" filter first. Otherwise, glyphs all point in the same direction, as in your screenshot.

Yvan,

Thank you for reply. But, I did apply "Cell Data to Point Data" in this case. Clicking the screenshot will enlarge the picture and show it more clearly. What can other reason be? Thanks.

Hello,

You may also need to first apply the "extract blocks" filter in case you have output both on volume and boundary meshes.

Otherwise, are the glyphs based on velocity ? As this is the only vector field in most cases, it should be the default, but it may be safe to check.

Yes, "extract blocks" is required to render it correctly (attached screenshot). Thanks Yvan.
