read parameters into UDF
does anybody has ideas about filling a UDF at start of simulation with parameters, so I don't have to rebuild the library when I change a parameter in UDF?
1. Do you mean that you want to write a UDF that modifies by itself?
2. Are you writing these UDF(s) for transient or steady-state simulations?
ad 1) My original idea was to load a file of parameters into UDMemories, that would be used by all cells or any other way to stuff the UDF without need to changing it. That would require a new compilation, i guess.
ad 2) Ideally both, but that also depends on the demands on memory. I think I can live with steady state simulation only.
Thanks for any help.
Have a look at the UDF-Manual ->Scheme Macros. I think that's what you need.
The way to do this is to define an rpvar. Once created in the CASE, rpvars are saved with the case file.
Rpvars are variables that can be passed to the UDF routines. Thus, you can easily modify the UDF without recompiling. Rpvars can be changed from the FLUENT GUI panel using simple scheme commands.
Look in the UDF manual on how to do this. If you need an example, please contact me directly:
