How to indicate velocity magnitude in tecplot with Flow-3d file?
 

I usually use the program 'Flow-3d'.

and I want to draw more specific picture using the tecplot with Flow-3d output file.

Flow-3d makes a data as "flsgrf.dat".

so I imported "flsgrf.dat" data in tecplot.

and I used the menu "Analyze" , "calculate variables".

and calculated "velocity magnitude" and then set the Contour, iso-Surfaces.

but Velocity magnitude didn't come out

so I checked the Data sheet and figured out

at the first time there's no data on U, V, W

U, V, W were indicated as "0"

Do you know why it happened?

what can I do to come out value of the U, V, W?

please help me

I got it

Please check the slide of z (k), because the coordinate maybe the solid part, there is no velocity, you should raise the z higher
