Hi.


I came across the attached tutorial of using Pointwise and OpenFOAM on an elbow case (unsteady turbulent). Please see attached a PDF (link). I did assume that the mentioned example and results are right and accordingly and I did everything as exactly mentioned.



1- The tutorial uses tutorial pitzDaily as a base file. The solver here is simpleFoam. It says that simpleFoam is unsteady solver which contradicts openFoam guidelines. How is that?



2- Also, I keep getting an error related to the floating point. Please see attached a screenshot. What might have gone wrong here?


I have tried the same inputs on pisoFoam but I get the same results


*I am using openFoam on ubuntu using a VM on windows 11.


Thank you.
