I hope this is not a stupid question
(CFX 12.1) I need to use the negative of the gradient of wall distance as an input to a particle tracking routine. CFX has the variable wall distance and I would like to define an additional variable for the negative gradient of the wall distance. In CFX pre I can click on the additional variable button and I can specify the variable type, the units, and the tensor type. I do not understand how I can cause the variable to be equal to the negative gradient of the wall distance. Where do I specify this? Also I assume that the tensor type will be a vector. Should the variable type be unspecified and the units be [m]? Or should I be using additional variable at all? Thanks in advance, tim |
