unsteady cyclic DPM injection

      HellonI'm going to simulate the diffusion of particles in the human body as it breathes.The flow field is transient. Since human respiration is in continuous circulation, DPM injection should also be in continuous circulation.I'm a beginner and don't quite understand how to set it up.I checked the help documentation and couldn't find a solution.nThanksn

      Do you want particles added all the time? n

      You can use a transient profile for the injection and make it cyclic. Transient profiles are documented in the Fluent Guide. The total mass flow rate of the particles will be then time dependent and cyclic (over certain period)n

      There is no need to inject particles into the body when the gas is inhaled, it is a cyclic process.n

      It is, how do you want to add particles to the system? Ie single injection at the start to see how they're in/exhaled or regular breathing in a dusty environment? n

      Transient injection profile should make the job.n
