Possible dependence to frame of references

[mkraposhin]

In file fwhFormulation.C I found next lines:

libAcoustics/Sources/lib/analogies/FfowcsWilliamsHawkings/fwhFormulation.C

Line 73 in b9cd1d6

sqr(r[0])+( 1 - sqr(mag(fwh_.U0_)/fwh_.c0_))*(sqr(r[1]) + sqr(r[2]))

libAcoustics/Sources/lib/analogies/FfowcsWilliamsHawkings/fwhFormulation.C

Line 76 in b9cd1d6

magrobs_[iObs][iSurf][i] = (-(mag(fwh_.U0_)/fwh_.c0_) * r[0] + R_)/(1 - sqr(mag(fwh_.U0_)/fwh_.c0_));

On these lines components of vectors r_ are used explicitly, meaning that libAcoustics is sticked to specific frame of reference. I think, that should be avoided, because we don't know in advance what frame of reference will be used by the library users.
