Drag Force

Is it possible to obtaion to drag force on something like "spur dike" from FLOW3D directly or indirectly?

Yes. Make the spur dike a separate component from the rest of the model. Under component properties > output turn on pressure and shear force outputs, and wetted area output. Then run. The output, integrated over the surface of the component, will be in Anaylze > Probe > General History data. There's a button on that tab to select graphical or text output.

Thank you very much
But could you explain more?
How we can exteract drag force efter that?

Sorry but is that force equal to all of the Forces?
I need Drift Force on the Object. more Specific, Second order Forces.
is there any way to extract this Force directly?
