I am new to CFD

Hello, I would like to get a clear Aerosimulation for my project but I am not sure if I have the correct settings. The main goal for my simulations would be to get correct data on how much Downforce/ Drag is created at certain speed. I would share in the following listing what parameters I choose and will also attach a link to the Results.

-Imported .step and build a external Cube arround it

  • did Boolean subtract with the cube and my Project
  • choose Incompressible and the material Air
  • Boundary condition Velocity Inlet on the front where the air is comming from
  • Pressure Outlet on the opposite site with 0 Pa
  • The other sides of the cube I choose wall and set it to Slip
  • Forces and moments I set the Center of rotation closely to the front middle off the cube/project
  • after the simulation I placed Particle trace in front of it and deactivated trace in both directions.

Are these parameters correct or did I miss something importand?

My next question would be regarding the data from the simulation. Is there a way to print it out or get a prefinished document where all important numbers and forces are listed?

My second question would be if there is a correct way to analyse the data. I can see when how much force is moving that´s clear, but I also have the waves. Is it better to have longer and flatter waves or what is generally saying the correct way to read the data?

My Project: SimScale Login

I know I am asking a lot but nevertheless I would appreciate it if someone with more experience could look over it and correct me.

Thank you and if you have any open questions please don´t hesitate to ask.

Greetings, Tim
