Determine and plot the superficial velocity

  1. Load your data as you already are.
  2. Select the Calculator filter pqCalculator
    • It’s conveniently located on the third toolbar all the way to the left.
  3. In the properties panel, change the Result Array Name from “Result” to something meaningful (such as SuperficialV). (optional)
  4. Set an expression (in the text box right underneath the Result Array Name) to the math expression you want. For example, if your specific velocity is in a variable named SpecificV and the constant radius is 6, you might set the expression to be SpecificV / 6.
    • You can use the buttoms and scalar/vector combo boxes right below to help you build the expression.
  5. Hit Apply.
