HI,

For a .dat output the option  “- - noequispaced” will stop dumping at equispaced points  but will put it at quadrature points.  I do not however know if this will work with vtu files. 

Cheers
Spencer

PS Checking at GLL points can be misleading since these points are only relevant when performing a collocation projection.

Dear all,

Is there some easy way in FieldConvert to write a vtu file with all fields computed on the GLL points instead of on equispaced element sub-meshes? For wall-y+ calculation it is the first GLL point away from the surface that should be checked, rather than the element height, which I think is given. Or when assessing if near-wall gradients are well resolved, it would be better to have fields plotted on a mesh that is representative of the modal resolution used.

Thanks.
