I have installed the latest version of butterfly with Blue-CFD. I downloaded the example file of the youtube Mostapha’s tutorial (01_0_outdoor_airflow).
I didn’t change anything and everything works but when I run the solver it is very slow compared with the video where it takes 1 sec/iteration while I have about 50 sec/iteration (see the clocktime in the attachment). What’s wrong? How could I get faster solution?
