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
