Dimensions of skewCorrectionVectors

cliffoi · June 2, 2009, 04:29

I am implementing a new surface interpolation scheme and have noticed that the skewCorrectionVectors class returns a dimensionless field. Shouldn't the dimensions of this field be dimLength, especially since this is dotted with the gradient of the field to obtain the correction?
Does anybody have any comments?

Hi Ivor,

Have a look at the non-orthogonal correction vectors and do the same

Hi Hrv,
Thanks for your replay and sorry for my delayed response. I did notice that this is not an issue if you work with the field components. I was just curious why the dimensions were not strictly correct.

Can you fix it?

Well, yes... just need to replace the keyword dimless with dimLength. I'm not so sure what the downstream result might be though. It seems like the only class which makes use of skewCorrectionVectors is skewCorrected so this is all that could potentially break (I hope). Here we go. If you would like me to upload it to the extend server, I don't yet have a login for this.

Regards
Ivor
