Hi Douglas,

Indeed, it makes perfectly sense and it is pretty handy like this. Sorry for claiming it as a bug.

Still, it would be nice to have a comment on this somewhere to remind the user. I have one more periodic direction with p-expansions where normalization is apparently not applied. It is a bit tricky like this.

Thanks,

Asim

Hi Asim,

Yes, the forces are per unit length.

I think this is a reasonable convention, considering in 3DH1D we have an infinite periodic domain.

Cheers,

Douglas

Subject: [Nektar-users] bug in aero-forces filter

Dear all,

I think there is a major bug in aero-forces filter for 3D1H case. It does not take into account the length in homogenous direction, LZ, while evaluating integrals. So LZ seems to be always 1.

So basically, all the calculated forces are wrong for 3D1H problems. My LZ is close to unity so I almost didn't notice it.

I was wondering if it is just calculating force on one slice or do some hidden normalization in third direction.

Best.
