hello everyone,
Could someone help me how to use UDF to apply forces on particles like drag, shear etc in 24.3.1 version of MFiX, Is there any tutorials where UDF have been used to apply new forces.

For the drag force, you can use usr_drag.f.

Thank you for your response, Along with usr_drag.f which other files need to be use

What force(s) specifically are you interested in adding? for TFM or DEM? etc, provide clearer infos to have tailored suggestions. Thanks.

I want to add lift and torque forces in DEM/SQP in case of elongated particles, to analyse the effect of lift and torque along with drag forces on fluidization behaviour of elongated particles.
