 June 10, 2003, 11:47 CFX4: 3d geometry #1 Ansah Guest   Posts: n/a Sponsored Links Hello I have been modelling a fluidised bed using a 2d geometry with the longest dimension deliberately drawn in the I direction. I am trying to generate a 3d version of the geometry, however, I have tried to produce the geometry such that the longest dimension is in the k-plane / z direction. When amending my USERINT file to define a continuous and dispersed phase, I am unable to produce a suitable bed height in the plane of choice i.e longest length in z dir. Whatever I try, it's as if CFX solver can only produce the bed height in the X-direction. Is it necessary to have to produce the geometry with the longest dimension in the x direction? thanks

If you are above the interfacial Z-plane, set phases to 0 and 1 appropriately. If below, set them reverse. Make sure you loop over ALL the nodes using INODE = 1,NNODE. Also, use the variables: ZERO = 1.0E-10 ONE = 1.0 - ZERO And use these variables to set your phases to either ONE or ZERO in each node. Jeff
