I think this has been discussed a lot in the past but I wanted a place for it to live in the vote section. So firstly what problems will this solve:
- Reduce convergence times for steady state simulations
- Reduce simulation times of transient simulations by removing time taken to reach fully developed flow.
- Make running a transient simulation from the beginning if it is cut short (out of time or cancelled because of divergence)
- Make it quicker to increase the simulation complexity (laminar to turbulent to transient)
If using results from say a laminar model for a turbulent model the initial conditions for the missing fields should be used.
Hope this sums up, but if I missed anything from previous posts feel free to chip in.
