Hello guys!

I am compiling an UDF for calculation dof the drag force between a gas and solid phase in a Fluent simulation that includes the Discrete Phase Module.

I would like to know the number of particles that are located in a cell in order to calculte a volume fraction of solid particles inside that cell. However, I have seen that all the UDF for the DPM are calculated for only particle at the time.

Please, tell me if you know a way to calculate or know the main properties of two or more particles with an UDF.

Thanks in advance for your important help

Best regards

You have do program an integration in a UDF
