Dear folks
I am doing transient flow analysis under porous medium . I set the porosity 0.5 I did domain interface .I set BC. I also did initialization. Still I have Global warning as stated below "In Analysis 'Flow Analysis 1' - Domain 'WATER': Transient analyses require that initial conditions are specified unless an Initial Values file is specified at run-time". Kindly give your advice to proceed the problem Thank you Shashwat |

I'm fairly new to the world of CFD, but have you tried running a Steady State analysis and using those as an Initial Values to your transient analysis? -Trues |

The error message is pretty obvious. You need to define an initial condition. You can either define an initial condition from a steady state run as suggested, or you can define it by domain or globally in the simulation setup. Either way, you have to define an initial condition somehow.

My input is 1D interpolation function,ie pressure(t). can I do steady state analysis? Regards Shashwat |

No. Steady state means all the boundaries are steady state as well.
