Hi all (dear Bernhard),

I try to use groovyBC with dynamicMesh in the pointMotionU file but I get a problem. The boundary condition itself is working but if I apply groovy I have no mesh smoothing with the laplacian solver anymore. Means my points at the surface are moved but the internal mesh is not smoothed anymore.

Here is some simple BC:
        type            groovyBC;
//        value           uniform 0.1; //groovyBC;

            "v=(time() < 60 ? 0.1 : 0);"

        fractionExpression      "1";
        gradientExpression      "0";
//        valueExpression         "toPoint(v)";
        valueExpression         "toPoint(0.1)";
        value                   uniform 0.1;
At least I apply 0.1 m/s in y-direction (component laplacian method) but the interior mesh is not moving.

Additionally, - only as a question - why is groovy outputing the weighting factors and points which are used for interpolation? Any reason, or was that for debugging?

If there is a solution please let me know.
At the moment I switched to the codedFixedValue (where everything is working fine).
Best regards,
Tobias Holzmann
