code_saturne User's Forum

Hello, I haven't run version 8.1 yet as there is some issue with compilation on the cluster. But I did some parametric study with v8.0. I ticked off the slope test option and gave a blending factor 0.95 both for the velocity scheme, both helped approach the measured drag force. I run steady simulati...

Hi Martin, Thank you for your help. I plot the X-axis component of "Shear Stress" from the postprocessing output of Code_Satrune on the Boundary surface, which is the solver's standard output file. The result plotted is circumferentially averaged. Yes, the x direction is the flow direction...

In addition to my previous post, I extracted the shear stress along the body. ANSYS Fluent gives 1% error compared with the total measured drag, so I suppose the shear stress predicted by Fluent is accurate. There is an overall shift of the Code_Sature results in the plot, which roughly accounts for...

Hi Martin,

I use the version 8.0

Best regards,

Dear developers, I'am new user to Code_Saturne. I am running an incompressible RANS simulation of flow past a axisymmetric body, illustrated below. The computed pressure coefficient along the body is perfect. However, the drag force is always ~20% higher than the measurement (which I believe is the ...
