Hey everyone, I made a new tutorial with more up to date meshing procedures! Here is the link to that video: ruclips.net/video/NpWgfA1xtWk/видео.html
excellent, I used this tutorial for my CFD project
Nice video, I found it useful
I want to create body-axis drag coefficient how to do
Hi, I am finding this video really useful. However, when I try to generate volume mesh I get this error 'ERROR region =air is not closed'. Could you please help me with this, I am very new to star ccm and need complete the project in 2 days. Thank you
If your region isn’t reading as closed you may be missing a face in the geometry feeding into the region, or that geometry isn’t manifold. Star needs to take in your geometry subtracted from a big box that essentially creates a single watertight part to mesh. If your region isn’t closed you’ll need to check and make sure that final part is indeed watertight
Great Tutorial . Do you have a tutorial or project about soccer ball drag force?
I’ve never done a soccer ball sim, but the process would be pretty similar. You wouldn’t need the rolling floor in the domain and you can use a local rotation rate if you want to simulate the ball spinning, this is what we do for tires on cars
GTMS - Georgia Tech??
Yeah I’m the Aero Lead for the the team right mow
why dont you subtract the block from the car model?
The block is the domain in which fluid flows, so you want to create a surface inside it with the body being tested. I think you’d have some issues with your output part and region going the other way
Sorry i meant subtraction the car from tunnel.. i cant see this process in video.. you added big tunnel but the car is still existing in this tunnel but the flow domain should be represented in the region where the interior of the car has to be avoided.
@@emregungor2969 did I use a subtract at all, it’s been a while since I made this and I use different procedures now
@@owenpatterson9355 no u didnt subtract it. But somehow it seems star deleted interior of car region.
@@emregungor2969 oh ok, well since the test body is completely within the domain, the surface wrapper just goes all the way around it to make the volume without issue. Our SAE team uses a subtract on half car models where the function remove half the car from the domain nowadays
