Hello Victor,

It seems to me that Nektar++ has not implemented the torque output for the moving body yet. I have modified the FilterMovingBody class to include the calculation and output of moment based on some code from FilterAeroForces class (https://gitlab.nektar.info/nektar/nektar/-/blob/feature/IncNS-FSI/library/SolverUtils/Filters/FilterAeroForces.cpp), and the modified files are attached. I hope it will work for you.

P.S., I am also working on simulation of flow around a rotating body, and got stuck on setting up the case. Could you share some experiences?

Best wishes,

Hello all,

I'm currently using the incompressible Navier-Stokes tool to measure the stability of bodies under torsional oscillation and I'm wondering if the IncNavierStokesSolver algorithm provides the value of the torque caused by the fluid in the body.

Could you please provide me this information and, if possible, where to get it?

Thanks in advance,

Best regards.
