Hello All,

I am using probes function to have data points at some locations in my domain. I have 2 questions.

1. If I use U as fields, I get the three components at of velocity at that point. Is there a way to get the magnitude of velocity at that point (like mag U) ?

2. For the location of the probes, I have different locations which changes with every test case, so I want the controlDict to read the locations from from a different file, where I have set the formula for the location points. How can I do this?

Thanks in advance for your help.

Dhruv.

Hi,

I'm not sure about the first question, maybe someone else can help you there.

For the second question; you can use include statements in your controlDict file,

        ...
        probeLocations
        (
#include "some/PATH/someFile"
	);
        ...

Where someFile contains your probes just as if you would have entered them without the include statement.

Good Luck

Thanks nsf,

I also looked in one of the tutorials, and found the same. I will try it today.

No worries,

Here's a trick I'd like to share for those new to linux and bash.

Let's say you wanted to find tutorial examples that use include statements in the controlDict file, this one-liner can help you

find $FOAM_TUTORIALS -name controlDict | xargs grep "#include"

the first command (find) will list all controlDict files in the tutorial folder. The pipe (|) will pass the list to xargs which will run grep "#include" once on each controlDict in the list.

Hopefully someone will find this useful .
