dear friends...

i am solving for potential distribution across a cylinder divided in three subregions..to set the properties in different region i have put such codings in lampr section

L0ELC=L0F(ANYZ(LBNAME('ELCO'),IZ))

DO IY=1,NY

ICELL=IY

IF(IZ.LE.10) THEN

F(L0ELC+ICELL)=3.0

ENDIF

IF(IZ.GT.10.AND.IZ.LE.20) THEN

F(L0ELC+ICELL)=0.00015

ENDIF

IF(IZ.GT.20) THEN

F(L0ELC+ICELL)=20.0

ENDIF

ENDDO

CALL FN0(LAMPR,LBNAME('ELCO'))

RETURN

previously i was using varyx commands(in case of cartes) to retrieve the data but now i want to write the values of variable(c1) in a file in the format used above..i tried but valuse are not the one which are there in result file .either i am unable to write iz slab wise values or u can help me out....

Just to try and open this question up a bit, as I dont completely understand.

Are you trying to set the Prandtl number/diffusivity for a variable you are solving C1 ?

Are you in ground Group 9 ?

I have never bumped into the variable ELCO, can you tell us what this is?

well thanks 4 ur reply..i am solving for a steady state potential distribution( cylindrical) by whole-field solver and have to set to properties for three different regions.so have to go into section 7 of group9 and set the laminar diffusivities of different regions .elco is defined by me to store the values of diffusive coefficient only..now as i run the programme i get correct distribution(values of c1) in result file but i want to write these in a file opened by user(me) ..or is there a way i can feed the laminar diffusivity coefficient in gr9 for cyl cordinate ...

I am not sure if I understood your question, but if you want to write your own file, you may do like this: (1) Go to the ground section just after the sentence "end of time step" (I am not with PHOENICS here, so I do not know exactly the number of the group) (2) use a traditional fortran code to: - open a file - write your data at this file using your format choice (use a fortran do loop to choose the positions you want to print) - close the file (3) recompile your code and run (use private option) I may sent an example if you need.

Good luck!
