Airfoil Batch Run with UDM export everytime

syedabdullah · November 20, 2020, 06:36

I am running a particle tracking simulation (on an airfoil) in Fluent that uses a UDF to store in the
user defined memory a number of parameters (angle of collision, velocity etc).
The UDM variables are there in the results section for plotting and i can export them to a file to work with them.
I want to run a batch simulation for a number of angle of attacks (changing inlet veloicty BC) so its a lot of work
Can i do something to automate the process so that the simulation can run for multiple number of AoA, export the UDM variables
to separate files for each simulation and start a new simulation for all AoA of the velocity inlet

you may define everything in journal file, and execute it

Can you explain a little bit?
how can i export the udm variables as xy plot files after each simulation of angle of attack

Find the commands to do what you want to do in the text user interface (TUI).
Once that works, put all these commands in a text file, and that is your journal file.
