HELP TIME on FLUENT
hello,
I simulated a fluid flow in a straight pipe with ANSYS Fluent : Inlet velocity : 0.116 m/s Outlet pressure 400 Pa with mass flow rate 0.063 kg/s Time step size: 60 seconds Number of time step: 5 Number of iterations / time step: 300 I find the same result I noticed that the solver resolves five blocks of 300 iterations each time, is it recalculates every time? 60 seconds is enough or must I fix a few minutes thank you very much |

isn't this a steady problem? none of your boundary conditions appear to be transient, your simulation will be steady even if you run a transient simulation. |

hello,
I try to simulate flow between two cylinders. Normally I should get a constant velocity profile along the length (figure 1). Attachment 13094 But, I found an acceleration along the entire length of the cylinder (figure 2). Attachment 13095 Change speed / length axis> 0 normally it must be = 0 I can not find the trick. Is that it's normal? thank you |
