Hello everyone,

I am about start working on writing an UDF to modify the drag law in the DPM framework. In particular I should use the Syamlal O'Brian (parametric with Umf and Epsilon on fluidization onset from the experiment) drag law as I did for the TFM in order to compare the 2 different methods afterwards. I know that there is an old tutorial for the TFM multiphase application (made when ansysis still did not have this feature already implemented inside) but now I am struggling to figure how to apply the same procedure into the DPM scheme. Does anyone have any idea at this regard?

Thanks a lot for your attention and support,

Leonardo
