Hi everyone,
I am working on a simulation that analyzes the effects of an ultrasonic wave (50 MHz) on structures within the vestibular system. I am using the FSI physics instead of the ASI physics because ASI does not include the nonlinearity of the acoustic radiation force that originates from the navier-stokes equations. The ultrasonic wave is implemented using an inlet BC with a time-dependent sine equation that creates a pressure wave that propagates through the fluid. I got the simulation to work but it took eleven hours to compute a study that ran for only 1 us. There were 500 time steps total. I need to be able to run the study for 200 ms. Does anyone have ideas for an efficient time-stepping method that uses a minimum of 4-10 time steps per wave cycle?
