I am using DDPM to track particles. Want to analyze net lift force vector (Not area averaged Force) acting on the particles at a particular cross-section, like at outlet.
Please help.July 6, 2021 at 9:01 pmSurya DebAnsys EmployeeHello,
I don;t think there is a direct way in Fluent GUI to extract lift forces on DPM particles.
But you may use UDFs to formulate the functional form of the lift forces and then output them.
Please check DEFINE_DPM_SCALAR_UPDATE in this link. [https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v211/en/flu_udf/flu_udf_sec_define_dpm_scalar_update.html].
For detailed lift formulations, you can check this link. [https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v211/en/flu_th/flu_th_disp_equations_particle_motion.html%23flu_th_disp_saffman_lift_force]
