uniformFixedValue for velocity

Hi All,

I am trying to use the uniformFixedValue BC in order to set a time dependent inlet velocity. The BC should ramp the inlet velocity from zero to some value within a given time. In previous OF versions this worked fine with the uniformFixedValue type with following code:

Code:

  inlet

  {

    type uniformFixedValue;

    uniformValue

    {

                value (-0.076 0 0);

                type scale;

                scale

                {

                        type quarterSineRamp;

                        start 0;

                        duration 10;

                }

    }

    value $internalField;

  }

However, now interFoam (OpenFOAM-dev) complains about the syntax: "... expected word ... found token '(' ..."
Does anyone have an idea, how to solve this problem?
Thanks in advance,
Jan

Just in case anyone else faces this problem. Was fixed here: https://github.com/OpenFOAM/OpenFOAM...db6a6c55938e13
