rhoSimpleFoam negative rho values
 

Hello there,

I am running a case in rhoSimpleFoam consisting of air flowing through a sixth of a cylinder with a "derivation". When the run is completed I proceed to map the results to another case, but then when I check the rho file there are -nan values.

Does anyone have a suggestion or thing what might have happened?
Thanks.

I am uploading my mesh and other relevant files in case there are questions.
