error when use swak4foam to calculate the mass flow rate of a cutting plane
I am new to openfoam and I use swak4foam to calculate the mass flow rate of a internal face, and I use the code in the controlDict as follows:
Code:
massFlowRate
{
type swakExpression;
valueType surface;
surfaceName interface;
outputControlMode outputTime;
writeStartTime off;
surface
{
type cuttingPlane;
functionObjectLibs ("libsampling.so");
planeType pointAndNormal;
pointAndNormalDict
{
basePoint (0 0.01 0); // Notet that the plane does not match up with the mesh
normalVector (0 1 0);
}
interpolate true;
}
expression "rho*U & Sf()";
accumulations (
sum
);
verbose true;
}
but error happens as follows afer running one timestep:
Code:

so, why the error happens? I am looking forward for your help.
thanks.
