Dear All;

I am trying to define a moving wall boundary condition, X component velocity will change with a function of sin().

the block below does not take calculated ux value. How can I get calculated value as a boundary condition like (ux 0 0) ?.

movingWall_1
{
type codedFixedValue;
value uniform (0 0 0);
redirectType rampedFixedValue;
code
#{

double ux=(0.5*sin(3.14*this->db().time().value())/2);

#};
}

best regards.
