DEar Foam users,

I am studying nozzle cavitating flow and using cavitatingfoam. Actually, i can take the data of mass flow at the inlet and outlet by using following definition (inside of controlDict)

functions
	{
  	  faceObj1
	  {
		type 	faceSource;
		functionObjectLibs ("libfieldFunctionObjects.so");
		enabled true;
		outputControl outputTime;
		log true;
		valueOutput true;
		source patch;
  		sourceName outlet;
		operation sum;
	        fields
		(
			phi
					
		);
	 }

As you can see domain section in the attachment figure, we have LDV measurement at sections, z=1.5, 3.0 and 6.0. Please could you help me that how can i get the velocity distribution at these section as shown at the attachment figure?

Thanks in advance

Hi George,

Look into the probing utility. If I remember correctly, then one of the pitzDaily tutorials gives an example on how to use it in runTime.

Best regards,

Greetings to all!

To complement Niels answer, you can find all of the tutorials that use function objects by running:

find $FOAM_TUTORIALS -name "controlDict" | xargs grep -sl functions

In addition, complete "sampleDict" and "probeDict" examples are available at the respective application source code folders:

• https://github.com/OpenFOAM/OpenFOAM...ple/sampleDict
• https://github.com/OpenFOAM/OpenFOAM...ons/probesDict

Best regards,
Bruno
