Hai

I am a beginner in CFD.

I wanted to know the difference in the accuracy of a commercial software solver such as between FLUENT and Openfoam.

Thanks in advance for your reply,

Have a great time.

For each package you can use different methods having several accuracy order. Therefore it makes no particular sense to compare the same accuracy order of Fluent and OF, it should be theoretically the same.
I think that other parameters must be considered in comparing them.
