Hi everyone,

Yes, switching to the incompressible FSI solver branch makes FilterAeroForces write the moment on the selected boundary (I don’t know if it’s exclusively in the FSI branch, but this s a way to do it).

To switch branches:
git clone http://gitlab.nektar.info/clone/nektar/nektar.git nektar++FSI
cd nektar++FSI
git checkout feature/IncNS-FSI
And compile as usual.

I hope this helps.
Best,
Robin

Hi Howard,

I think it is might be possible to get the AeroFocres filter  to write out the moment force too. At least it does appear for some solvers. 

@Robin: Is there an option to write the moment force you are using in your simulations? 

Cheers,
Spencer.

Dear all,

I would like to know how to monitor the torsional aerodynamic force for a 2D square cylinder when using IncNavierStokesSolver? As far as I know, the Filters "AeroForces" can only monitor the drag and lift forces.

Thank you in advance for help.
Kind regards,

Howard
