please help-time varying inlet velocity
i m new to phoenics. My inlet velocity is varying with time which i know, how should i set the time varying inlet velocity in phoenics for transient simulation. please help me.
time varying inlet velocity
Simples to specify in Q1 the inlet boundary conditions for variables p1, u1, v1 and/or w1
at each time step. For example
at 1st time step
PATCH(TIME1,CELL,1,NX,1,NY,1,NZ,1,1) (here 1,1 first and last time step are 1)
COVAL(TIME1,P1 ... ) ('...' is your conditions)
COVAL(TIME1,U1 ... )
COVAL(TIME1,V1 ... )
at 2nd time step
COVAL(TIME2,P1 ... )
COVAL(TIME2,U1 ... )
COVAL(TIME2,V1 ... )
For more complex problem You can use In-Form feature which can set souces by formula.
This formula can contain the variables TIM (current time, seconds) and ISTEP (number of current time step).
