i unerstand that,
first we should write potentialFoam instead of simoleFoam in controlDict, after some iteration we should turn the turbulence off in RAS properties, and then after some iteration we should set the turbulence on in RAS properties, is it rigth?
thank you very uch

Hi saeideh,

No, you should start simpleFoam with turbulence turned off. Lateron you can turn turbulence on again.

Best regards,
