Hey Simscale community,
First of all it is very nice to work with Simscale because it has a nice and friendly user interface and a very nice support.
I’m using Simscale to analyse a the aerodynamics of a FSAE racecar. The simulation is working, but there are some points where I your need help.
The simulation is not using Yaw studies, just a simple straight flow CFD simulation, with MRF zones and porous media.
You can see, there are some wrong airzones in the frontwheel. Is it based on an issue with the CAD-geometry? I use a STL master file where are all parts included.
Usually in the marked area should be to see the radiator. In the Mesh Creator and Simulation Designer it is shown, but in the Post Processor it is missing. What could be the problem on this?
The simulation results are not convergent, what could be the reason for this? Are there more simulation time steps needed than 3000?
Quiet Similar to #3, the force plot of the rearwheel is not convergent. How can the setup of the simulation be improved, to get nice and clear results?
The force plot of the radiator shroud gives a negative force in x direction. This would mean, it gives a forward force instead of a breaking force. This can’t be right.
Well, a few questions and problems which need attention.
I’m looking forward to your ideas and tips for solving them.
