IPALL giving NULL values

Hi everybody,
I know there may be time consuming for you to read this post but, here I go. Have anyone ever noticed a possible fail in the IPALL utility routine in CFX-4? I'm meaning this because I defined a region (USER2D), which is located exactly in an interblock boundary, in CFX-BUILD, and when I submit the job using USRTRN, in the output file I got null values of every properties I want to print in that region [i.e U(INODE,1)=V(INODE,1)=W(INODE,1)=P(INODE,1)=0.000, where 1 is my default phase, air]. I'm running two cases with two different geometry and is a gas-solid flow with a grid containing less than 12k cells. The funny part is, some days ago I did the same thing with another grid and did work very well, I could obtain every property I wanted, but now I'm not able to extract the information recquired. And another thing, when I check those values, IPALL gives me correct AREA without giving me the correct values. My utility routine is showed below, it is an area weighted average pressure of phase 1 (my example was extracted and changed from the manual). CALL IPALL('USER2D-P0','*','PATCH','CENTRES',IPT,NPT,CWORK ,IWORK) PSUM = 0. DO 201 I=1,NPT INODE=IPT(I) IBDRY=INODE-NCELL IFACE=IPFACB(IBDRY) AREAM=SQRT(AREA(IFACE,1)**2+AREA(IFACE,2)**2+AREA( IFACE,3)**2) TAREA=TAREA+AREAM PSUM=PSUM+P(INODE,1)*AREAM 201 CONTINUE USP0 = PSUM/TAREA/1.E+05 As I said, IPALL prints the correct total area on my USER2D (TAREA variable) and if I put a write(6,*) in the loop's middle, every property has null value. I have checked and changed several things in the fortran file and the grid, but I could not obtain any success. Sorry for the long message, but any suggestions will be really appreciated. Kind regards, cfd guy |
