    Hi,

    I am running the simulations of lesson 13. I am starting from the given setup and using a solution at Re=110 with the fixed cylinder after 300s of simulation. After a couple of tests, all the simulations crash at 396s because continuity errors blow up. It looks something like the timestep becomes too long or something like this.

    How can I proceed?

    Hi,

    Please check that you have updated the input files correctly. Few other students managed to run this case without any issue.

    Please go back to the lecture recording where I modify the files, especially boundary conditions for moving boundaries for velocity and pressure, and see if you missed anything.
