  Hello everyone!nI'm simulating FSI with Fluent and Transient structural modules.nThe timestep is 1e-6 (set in Systemcoupling). How can I set time interval to transfer data which is different from timestep? ( That means timestep is 1e-6 but the data is transfered every 1e-3)nThank you so much!n

  Hi,nnPlease see if the following post may be of help to you:nn
  I'm performing one-way FSI simulation with Fluent and Structures using system coupling module.My question is: Is it possible to define a specific time step for Fluent model, other for the Structures model (being a multiple of the Fluent one) and then define a system coupling equal to the Structures?As example: Fluent time step: 0.01Structures time step: 0.1System Coupling time step: 0.1So, fluent model performs 10 time steps and then transfer the data for the structural model.Thankshttps://forum.ansys.com/discussion/20230/is-it-possible-to-define-different-time-step-sizes-in-a-system-coupling-simulation
