Error compresible simulation

Sergio González

Good afternoon,

I am trying to perform a simulation taking into account the compressibility of the air and I always get the same error. I have tried changing the material as ideal gas air, absolute pressure in the solver and output pressure of one atmosphere, and still the same error continues. I attach an image of the error I get in the simulation log.

 

Please, can you help me with the problem? 

Thank you very much. 

Best regards, 

Sergio

One of the versions was writing the input file incorrectly. You'll need to edit the input file, and use

type = fluid

instead of type = ideal_gas

Also - the compressible solver is intended for internal flows at transonic/supersonic (up to Ma 1.5 or so) speeds. If you're below Ma 0.7 or so, you can use the standard/incompressible solver, but still use ideal gas density to capture variable density effects.
