Propeller airflow simulation error

Hello Everyone,

I would like to run simulations regarding different propeller’s efficiency. I have found this article, which seems to be very useful:

and I have tried to run the same project which is linked within the article.

I have checked the simulation results and there I see the simulated thrust values, but I am missing the link how can we get the efficiency value at the end? I have searched amongst the settings and results but did not find any parameter which corresponds with propeller’s input power.
I am very new i Simscale and in these simulations, so maybe I haven’t noticed something.

I also tried to re-run the same simulation, but I have met some problems.
I tried to re-create the mesh, but I got the following error message:
“Mapping of assignments from geometry to mesh failed.”

When I tried to run the sim, it just stopped without any specific error message.

I hope someone can help to discover what is the problem or link some relevant material where the answer can be found :slight_smile:

Hey there, and welcome to the forum!

This article and the sample project are rather old, and thus outdated due to the improvements that have been performed to the platform.
