I’m trying to simulate an FSAE car in a cornering condition using a curved domain as in this setup from Star-CCM+. They say to use a zero velocity inlet boundary condition and a zero pressure outlet boundary condition, however Simscale does not allow a zero velocity inlet condition. I’ve tried using…

Hey @wbleier , Thanks for posting on the Forum. As you see in the image below, the custom pressure boundary condition is only applied to the outlet face in your project. This is an incorrect setup. It might be helpful to look at the finished drone tutorial project to visualize the faces to which t…

Thanks for the reply. That is still a very small amount of cells relative to the total cell count - is that still a problem? Do you have any recommendations for changing my mesh parameters?

Hey @wbleier , Could you share a screenshot of the error? Do you see the message ‘an error occurred’ ?

Yes that’s the error I see. [image]

Hey @wbleier I suspect the touching of the outer domain face and the rotating wall face maybe causing the issue here. Could you try having a small gap between the car and the ground face to avoid this issue. Similar to what has been done in this tutorial: Tutorial: Incompressible Flow around a Form…

@shenoy I’ve made some progress by creating a separate volume and defining it as the MRF zone, as well as a “cell zone” which gets me further before the sim fails (in addition to raising the car a bit). I am now getting the below error. In a previous mesh run I didn’t define the MRF zone as a cell …

Hey Satvik,

I’m getting a blank error with no other information when I try to run the sim. How can I get more detail?
