Hey dear guys. I need your help.I am doing inner flow analysis.

Always I do this analysis in CFX . But I want to test FLUENT's power. How different are the solution times ? etc...

This component is an injector. I have a lot of expressions when using CFX. There are an example below picture. My purpose is doing same analysis in FLUENT.

I need these expressions to control TAU angle ksi angle.. etc.. I should see TAU Angle values end of the analysis on postprocess.

I am using VOF model on FLUENT but you know VOF model has some limitations. So I don't acquire velocity components each phase. Such as fuel superficial velocity X Y and Z.

I guess I have to write UDF to acquire these components. And then I will use this component for aquiring TAU and ksi angle But I don't know writing UDF codes.

this ksi angle is below picture. . My whole purpose is to post process this.

Can you help me.

Then I will Vof to DPM analysis for spray. My one of purposes is to use VOF to DPM model on FLUENT. for detailed information

Hi metafizix,

Do you have the tutorial of the Fluent VOF-to-DPM model. I can not find the tutorial from the Ansys customer portal. Please send it me if you have. My email address is: Thanks in advance.

Best Regards,
