Forces calculation after simulation has finished

miuzZz · September 9, 2011, 17:41

Hi guys,
I would like to know if there is a way to calculate forces and/or force coefficients after the simulation is already finished, without having to re-simulate from the start.
Thanks

Hi, did you manage how to solve this problem. I'm stuck with the same problem!

Do you really need the forces from each timestep? Why dont you just run the calculation for a couple more iterations and evaluate it then?

Does anyone know how to proceed the force calculation after a long simulation (cost several weeks)?

Hello everybody,

did anyone solve the problem? I would like to know if you can wirte out forces from your timesteps after the simulation has finished. And if it works how would I do this?

thx for replies!

You can execute the following to generate the wallShearStress variable:

Code:

wallShearStress

Now you can integrate pressure and wall shear stress to get the viscous and
normal components acting on a particular patch:

Code:

patchIntegrate p <patchName>
patchIntegate wallShearStress <patchName>
