Hello everyone! I hope everyone is safe and healthy during these challenging times. I was just wondering if someone could help me find the drag coefficient of a 3d model I have created. I have already ran a simulation and I just need help with the post processing, especially the drag coefficient. Thank you!
The link to my project:
CFD Squad, can you help out our user here. Also tagging @dschroeder!
All the best!
Please take a look at to following SimScale documentation:
How to Analyze the Pitch, Lift and Drag Coefficients.
Thank you for the documentation. However, I am afraid to say that I don’t quite understand, considering that I have a meshed domain.
What I do is to postprocess the results in Paraview.
There you can find the Lift and Drag forces, therefore the coefficients.
@sungjoo_lim: you do not need Paraview in order to get CD (drag coefficient). It can be calculated in SimScale simulation.
However I still suggest that you study a bit more the documentation about CD. Here is an easy explanation:
In Simscale, you have to user ‘Result control > Forces and moments > Forces and moments coefficients’. However you have to know the ‘Reference area value’ of your geometry. Documentation mentioned above should allow you to understand the need for that area.
Hello @Retsam ,
Thank you for the document, it was clear and easy to follow.
I was wondering if there is an example of a project/simulation that finds the drag coefficient to see how the inputs and post processing would look like.
You can refer to my latest project where I aim to validate and check CL/CD values for various different aerofoil shapes and configs for 2D or 3D geometries.
Do look through it and if you have any questions feel free to ask here.
