Dear All,

 

How to define the user defined function in Acu field view??

 

Kindly provide some tutorials on Acusolve.

 

Thanks

    Attached a screenshot of Kelvin to Celsius.

     

    Refer to Chapter 2 of FV_Reference_Manual.pdf from AcuFieldView Help menu for more details.

    How to define a function using quantities which are not available in quantity box? Example: surface body pressure is available. I want to plot body surface pressure coefficient. Please help me.

    First determine what it the definition/formula for the quantity you wish to calculate - I suppose surface pressure coefficient in this case.  Then you should be able to use the available quantities in AcuFV (pressure, velocity, etc), along with other constants you may need to calculate yourself, in order to define the equation (as shown above) for your desired quantity.

    To start - what is the definition/formula you wish to use for surface pressure coefficient?

    Thank you for your response. But i was looking for the few quantity like density or initial pressure or any other quantities used in simulation which was not available in the quantity selection box.

    You'll just enter (type in) those quantities/constants to the formula area as you define your function, as shown with the '-273' in the original image posted above.
