Hello everyone~
I'm newbie of OpenFOAM and I got a problem.

I've generated CFD but it doesn't work.
I've found that "No MRF models present" but I don't know why this occurs.
Can you guys check my file?
Below is my Github link.

Thank you

Hi Sangho Ko,

No MRF models present is not an error, it's just telling you there is no MRF model in your case. (it could be an error if you intended running your case with MRF). Same goes for the No finite volume options present.

You actual problem is located in the controlDict file:

Code:
application     pimpleFoam;
startFrom       latestTime;
startTime       0;
stopAt          endTime;
endTime         1e-5;
deltaT          0.025;
Your endTime is set to 1e-5, but your timeStep is set to 0.025. Since your endTime is smaller than your timeStep, the solver does solve anything.

Regards,
Yann

Oh I was just foolish.
Thank you for your help!
