Hello Foamers, I am trying to develop Boundary Condition Using codedMixed boundary condition, For a time interval outlet will be zeroGradient and next time, it will be FixedValue but the fixedValue needs to take value at an outlet when ZeroGradient ends. Here is the used code..

type codedMixed;

refValue uniform 0;

refGradient uniform 0;

valueFraction uniform 1;

name codedPatchBC_lobe_1;

code

#{

const scalar t = this->db().time().value();

const scalar pi = constant::mathematical:i;

const scalar sign_check=sin(2*pi*t/4);



if (pos0(sign_check) == 1)//f=0,zeroGradient

{

scalarField& field = *this;



this->refValue() = field;

this->valueFraction() = 0;

this->refGrad() = 0;





}

else//f=1,FixedValue

{

scalarField& field = *this;

this->valueFraction() = 1;

this->refValue() = field;

this->refGrad() = 0;

}



#};
But I am not getting the result, near the outlet, its getting zero, Is this problem something related to *this ?
any help will be much appreciated, Thanks For your time
