delete results before new analysis?
 

Hello,

I have varied my setings in turbfoam Modell and I'm surprised about results. The are hardly to alter:confused:.

Before start a new solve of analysis, must I delete the old results in project folder?

Greeting Markus

That depends greatly upon what you have in your system/controlDict for the "startFrom" entry. If you don't specify it, it defaults to 'latestTime'.

Having said that, I generally delete old results before redoing an analysis.
It is cleaner and clearer that what.
One common mistake that can also occur is changing the initial boundary conditions, but forgetting to decompose these fields again (for parallel processing).
