dynamic pressure and pressure drop

I'm doing a pipe flow analysis. I am new to CFD and also in the use of AcuConsole. I wonder how you see the variation of dynamic pressure (can only see the static) as well as be able to view the pressure drop. Thank you very much in advance!

    As you've noted, the 'pressure' variable is static pressure.  Dynamic pressure would be 0.5 * Density * Vel^2.  In AcuFieldView you can create that variable if you click on the 'fx' icon.  There you can use functions like magnitude, absolute value, etc - and make equations to define a new variable.  Then you can create contours of that new scalar variable.

     

    If you want to compare inlet pressure to outlet pressure, you can view that in AcuProbe using the Integrated Surface data for the desired surfaces.

    Thank you, compared to loss of pressure , you know something?
