cfx-tascflow transient boundary conditions
 

Hello, I'am trying to impose a transient total mass flow at the inlet. I modified the bcdtrn.f, and i wonder where to specify the proper label in tascflow in order to read the total mass flow value.

Thanks for your help.

Donatien.

This is a part of my bcdtrn.f

VAL = 0.0

KEY = 999

n=99

T=0.75

pi=4.*atan(1.)

IF (LABEL.EQ.'TOTAL_MASS_FLOW') THEN C-------- Total mass flow though ALL faces assigned a transient mass b.c C VAL = ((2 * STIME * STIME) + (0.25 * STIME))

VAL=ao*0.5

DO i=1,n

f=2.*pi*float(i)/T

VAL=VAL+a(i)*cos(f*STIME)+b(i)*sin(f*STIME)

ENDDO

ENDIF C

RETURN

END
