Hello,

I got a two phase flow in a plate with two inlets. The second inlet should open at a specified time like:

inlet
 {
 type            totalPressure;
        p0              uniform 100000;
        U               U;
        phi             phi;
        rho             rho;
        psi             none;
        gamma           1;
        value           uniform 0;
 }
 inlet2
 {
 type                 groovyBC;
 valueExpression  "(time()<t0) ? 0 : 1*(pinlet)";           //zeroGradient for time()<t0 (wall), constant value for time()>t0 (pressureInlet)
 variables            "t0=0.1;pinlet@inlet=p;p=100000;";
 value uniform      100000;
 }
 outlet
 {
  type fixedValue;
  value uniform 0.000000;
 }
 outlet2
 {
  type fixedValue;
  value uniform 0.000000;
 }
 
 wall
 {
  type zeroGradient;
 }
 frontback
 {
  type empty;
 }

This case works fine. Now I want to open inlet2 depending on a field value like pressure, alpha volume fraction etc. Is that possible in some way? Thanks for any advice.

Kind regards, Nico
