Hi all,

I'm doing a series of 2D transient simulations of separated and reattached flow past a sharp-edged rectangular body.
According to previous recommendations on this forum, I opted to set an adaptive timestep based on a target minimum/maximum number of coefficient loops to ensure a proper temporal resolution, which leads to very small timesteps in my simulation.
Despite initializing the simulation using a relevant solution previously obtained, the initial transient part of the solution appears to take a very long simulation time to fade, considering the small timesteps imposed by the adaptive timestepping. This is unfortunately beyond the computational resources available to me.
I'm wondering what could be done to reach the stationary solution faster since I'm not interested in the initial transient part. Is it reasonable to manually choose a much bigger timestep?

I appreciate any comments.
