Hi,

There is a steady state solver you might try. It was a while since I have attempted to use it, but I think you need to set the driver to SteadyState, and not change the Eqtype. Have a look at the manual sections 11.1.4 and 11.5.

My personal experience was, that it was easier for me to run the non stationary, standard solver towards a stationary solution, rather than to use the steady state one, even in the case of potentially unstable flows.

Hope this helps, cheers!

Hello,

I need to calculate a steady flow which may be unstable.

Is the option

<I PROPERTY="EQTYPE" VALUE="SteadyLinearisedNS"/>

can be used only for Re<<1 or it is possble to make an appropriate AdvectionVelocity section for large Re?
