ive set it up, as far as im aware, no different to all the other simulations i have run buit this simulation is producing no results, any guidance? https://www.simscale.com/workbench/?pid=4213422541826463357#tab_0-0
Having a look at it and will get back to you as soon as I know more!
There you go: AeroGlider - CFD TestSim. Reduced the mesh fineness just to give it a quick spin. Adapt the case if you like and change it according to your needs - seems to work now.
was the fineness the issue? i had it set high because the first mesh i made on 4 the mesh was too fat and it removed the hull, so i reduiced domaiin size and increased fineness
I removed the moving wall velocity and changed it to the slip boundary condition - which worked!
hmmm weird, been using that for all things in close proximity to the ground, cheers
If you want to model the airplane effects near to the ground try using the normal wall BC with no-slip settings.
still not generating results for me, trying a wholenew simulation run to see if it works
@Lemlurker Your mesh is 24 million cells - therefore, it takes a while for the domain decomposition to finish. It seems that the job is timing out before this step can finish. Try increasing the runtime.
okay running two, as a new simulation on one with a shorter time step but same run time, and another with a whole new project with 3x the run time
To be sure, did you change the right parameter?
I was referring to the one called “Maximum runtime [s]”. It is by default set to 3000 seconds (50 minutes). I guess the decomposition itself could take around 30-40 minutes. Please set it to 3 hours or so (15000 seconds).
okie, and yea changed alt of
