How do i convert facet-only geometry into advanced geometry?

Im looking to make a flow simulation that would test how the different shapes of valves change the airflow into an engine chamber.
However, im unable to perform the simulation due to this:
This geometry contains facets that can not be translated into advanced geometry. Therefore it can only be used for Incompressible (LBM) and Pedestrian Wind Comfort analyses.
How do i turn this facet-only geometry into an advanced geometry so i can use it in compressible fluid simulation?

Hi @max_crespo, thanks for posting on the forum :slight_smile:

Welcome to the SimScale Community :handshake:

Could you kindly share the URL to your project? Maybe disabling this option on import might help:

Best,
Igor

Thanks a lot
I was able to solve the problem
