query point value

Hi,

I'm searching for a solution to query the value of a single point/node, but I've not been able to find the solution in the docs, I could solve it by selecting all nodes and then remove the unwanted ones with a filter, but this is ugly as hell.

Concrete case: It's an heating element(patch) and it should go on and off depending on the T value of a point.

the correct function/call would be a great help :)

Code:

funcName

{

  type swakExpression;

  valueType set;

  setName onePoint; // This causes a single scalar value to be written

  outputControlMode timeStep;

  outputInterval 1;

  verbose true;

  set {

    type cloud;

    axis x; // ??

    points (

      (0 0 0) // your point(s): (x y z)

    );

    setName onePoint;

  }



  accumulations (

    average

  );



  expression "do something fun";

}

I'm not sure what lib I needed for this specific functionObject, but these are all libs I have active:

Code:

libs

(

        "libsimpleFunctionObjects.so"



        "libsimpleSwakFunctionObjects.so"

        "libswakLagrangianParser.so"

        "libswakFunctionObjects.so"

        "libsimpleLagrangianFunctionObjects.so"

);

Thank you,

I'll test it tomorrow.

And I think it is ok now to be paranoid, I'm tracked by particles everywhere :D
