The first time I ran the demo case, with a clean looking install, I mistakenly stopped it after 1500+ iterations, thinking there was something wrong.
Since then I've upgraded to OF3.0.0 and better hardware, but have not had a successful run, either with my own geometry, or the demo one.
openFoam keeps complaining about "no times set" from reconstructPar.c
I've started looking over release notes for OF3.0.0 and it appears to break backwards compatibility with OF2.x.x. I'm building a virtual box to explore the changes now. Basically, you'll need to modify the scripts in the template directory of dronecfd to work with OF3. We'll also need to add a version check to make sure we copy the correct template files.
