 August 25, 2004, 13:56 XYZ Coordinate #1 RK Guest   Posts: n/a Hello: I am using USTRN to write out Temperature values at all nodes in particular a block. With these temperature values, I would also like to write the X, Y, & Z values (which are distances and therefore it should be in units of meters) at the corresponding temperature value. Thus the output file created would look like as shown below; four column with particular values. X/ Y/ Z/ T/ 0.0/ 0.0/ 0.0/ 2.0E-03 I hope this makes some sense. Does any one know how to do the above? Thanks in advance. RK

Loop over the nodes in the block, or 3D Patch (this is the recommended method then you can re-block if you want to). Then access the arrays XP,YP,ZP to get the three coordinates of the cell center. Temperature is in the T array...... CALL IPALL('PATCH NAME','USER3D','PATCH','CENTERS',IPT,NPT,CWORK,IWO RK) IPHASE = 1 DO I = 1,NPT ! Loop over all cells INODE = IPT(I) ! Get node index X = XP(INODE) ! Get X coordinate Y = YP(INODE) ! Get Y coordinate Z = ZP(INODE) ! Get Z coordinate TEMP = T(INODE,IPHASE) ! Get Temperature value WRITE(*,*) X,Y,Z,TEMP ! Write values out ENDDO If you must loop over the block (instead of a USER3D patch) then use IPREC instead of IPALL (different parameter list), but you can only do one block at a time. I suggest you get in the habit of defining USER3D patches for your regions of interest as they can cover multiple blocks. Jeff
