Hey,

I wonder if automatic time step is supported by the icoFsiElasticNonLinULSolidFoam solver?

I have a simulation which crashes due to high Couranr numbers. So, I wanted to set adjustTimeStep to yes and maxCo to 0.5 to make OF take care about the timesteps. But somehow simulations are still defined by deltaT…?

Thanks

Sorry for my question, but you use the solver which is very interesting to me. You said that you have the stability problems due to the high Courant number. But my question is: do you have any OTHER problems with solver ? I and some guys here cannot properly run it for even a simple FSI simulations (for example, elastic pipe). Our simulations crashes but it is not because of high Courant number, it's something else... So, do you have a stable and reliable solution of FSI problem or your simulations also crashes ? Maybe you've already find a way how to fix FSI solver...
Thanks

No, I don't have any other problems with this solver... I have already run it for some other cases and it worked very well.

How did you define your time step? Do you use automatic time step or have you defined one manually?
