Dale, thanks for the input. I also agree that getting this right is important. The tutorial values i shared in the post but maybe i shouldn’t have called it Tutorial values if that was confusing. this is what i was talking about
Using the inflate boundary layer settings provided by the FSAE Step-by-Step Tutorial: Homework of Session 2.
This link is step by step instructions for setting up a half car simulation of an FSAE car for the Simscale Academy. In it are all suggested settings and refinements needed to complete a mesh and simulation. It is meant as a tutorial for students new to Simscale that are trying to learn CFD for FSAE purposes.
Here is the suggested inflate boundary layer settings from this Tutorial
Which results in this first layer thickness - 0.408m
I agree that setting to Y+ of 50 to get a stable boundary layer then tuning from there is a great idea. I will do that for sure.
