Hello Everyone, @varunsura , @PhilippB94 , @durgesh786 , @agupta , @fhnx , @LoganZundel , @slibbi , @kianz89 IMPORTANT NOTE: for all who are facing issue of strange simulation results e.g the figure below [image] What was causing this ? The reason for this was a lot of illegal cells ( bad quality …

Hi @melia , you have to deselect the zones from the car boundary condition… [image]

When i go to import the link that has the file of the homework to my projects, i am getting an error. It takes me back to my dashboard and does not let me view the file. Can i get the file from somewhere else?

@varunsura @fhnx @ahmedhussain18 @Milad_Mafi Greetings, I am having the same situation. Mesh and Simulation parameters were checked two times and I am having the same output. I was wondering if you could check my model, just in case ( https://www.simscale.com/workbench?publiclink=4c7fcf28-2ba6-41e…

Hi @afuente , Your solution is not converged, but you have to zoom-in in order to see that. [image] Step-by-Step Tutorial: Homework of Session 2 Fluid Flow / CFD Hi @varunsura , @fhnx , @LoganZundel Your solutions are not fully converged. You’ll need to run about 6000 itera…

Hi guys, perhaps you can help me with my problem. meshing the full car was working great. Now i want to start Simulating by adding the Material “air” by following the tutorial and select region0; FrontWheelZone; RearWheelZone and Radiator. But in my Simulation-Area I cannot select the radiator. …

Hi, @afuente , @varunsura , @LoganZundel I did a rerun of my simulation (wirth MRF and rotating wheels) with 6k timesteps, as @pfernandez suggested. As you can see the graphs converge at around 4k timesteps. So if you want to run your simulation on your own I would suggest that you run it with at le…

I don’t get it… I only got config 1-2 for my simulation as a model and not config 3 and I don’t get whether we shall do 1 simulation or 3 simulations? Can someone help? I guess I have the wrong project?? Thank you :slight_smile:

You should do only one simulation with MRF-zones and rotating wheels, as described in the tutorial. If you have the model with the MRF-zones (the “wheel-caps”), then you have the right model

Greetings, I am currently rescaling the pressure contour at post-processing however as is shown in the picture I can only see an slim section of the car, which steps should I follow to be able to see the rest of the car? [image] Also I would like to know if the results on the viewer are correct …

Hi, @jkollautz,

You have to create the cellZone for the radiator by setting the option to true. You’ll have to re-mesh the geometry.
