Variable BC in time and space for transient run
Dear all,
I want to set up a boundary conditions using a function with 2 variables using CFX-10 Pre. I know how to set up a function of one variable (space or time for ex.) by importing a text file (create user function), but I cannot find out how to impose a BC function of space AND time. Any help is highly appreciated! Thanks!! Porry |
UDF space AND time
The same for me in Fluent:)

There's really no good way to do this in CFX. If you only have a few timestep, then you can set up a CEL expression that contains a series of if() statements all summed together, so different files get read at different timesteps. But that's not practical for many timesteps and it's not interpolating data in time, it's just using a different file at different timesteps.
