So nice. Really helpful and friendly to beginners.

It's a compilation of nice and useful tips there! I wish some key screeshots with settings from this video would be available online.

Thank you for the video, it is really helpful!

Very useful input. Thank YOU much, inDEED!

How can I draw streamlines starting from a certain surface (like what Fluent does)?

what format do you use to import the cad files? I have used .STL in the past and i always get small anomalies in my mesh and thus the Cp curve isn't that sooth as in the video. I have tried a lot of settings for the meshing, without much success and was wondering if the file format is important.

@Jousef Murad Could you please explain how you find the centre of pressure location? You explained lift and drag, but not the load distribution between front and rear wheels.

The drag calculator applied does not take frictional forces into account right ? The integrated value obtained would be different from forces function present in OF.

If I did not calculated Shear stress in OpenFOam since the beginning can I calculate it with the calculatror filter using the formula of shear stress? Does any one have done this?

The field calculator within the post-processor is limited to operations within individual cells. However, the computation of shear stresses requires the calculation of velocity gradients, a process that involves traversing cells within the boundary layer. Due to this requirement, performing such computations solely within the post-processor is not possible. To address this, we recommend activating the option for wall shear stresses within the field calculations prior to the simulation run.

The wallShearStress tab was not available to me, how do I get access to this?

Hello Isaiah, you have to run the OpenFoam postProcess utility "postProcess". After you simulation is over, run in a terminal from your case diretory (version 6): >> -postProcess -func wallShearStress This will write a file for each time step written folder, just like the other variables like U (vector) and p (scalar), and a .dat file in postProcess/0 folder.

Nooooo. Don't use a rainbow color scale! It's not good for visualizing data. Like at all. Paraview has so many better options, like black-body radiation, Magma, Inferno, Plasma, and (my favorite) Viridis. They've all been specifically designed to correctly reflect the data and allow for good visualization. Even the default (Cool to Warm) is significantly better than rainbow. There's a reason it's default.
