User Defined G-Equation

cshsgy · April 2, 2019, 16:18

Hi all,
I am trying to conduct an engine simulation with turbulent combustion modeled. My professor indicated that it would be better if I use a UDF to specify the laminar flame speed that is required instead of using Gulder model. I am wondering whether there is any example cases or instructions about how I should write the UDF files. Could anyone kindly give me a hand? I'll appreciate it a lot!

Hello,

You can get to our website (https://convergecfd.com/), then click on Login in the upper right hand corner to be directed to the downloads site login screen. Once you are logged in, you can find the advanced training slides at Root > CONVERGE_2.4 > Training_Materials > Advanced_CONVERGE_Training. Where you can find examples and training material for using UDFs.

Best regards,
