Thanks Luca. I have been looking at tests also. For CompositionManifold, if
H = CompositionManifold(F, G) then H_pullback = F_pullback * G_pullback H_pushforward = G_pushforward * F_pushforward I think adding this to documentation will improve the description. Also this line dim1 The dimension of the first ChartManifold <https://www.dealii.org/developer/doxygen/deal.II/classChartManifold.html>, which coincides also with the chart dimension of the second ChartManifold <https://www.dealii.org/developer/doxygen/deal.II/classChartManifold.html> does not seem to be correct in my case static const PolarManifold<2,3> sphere; static const FunctionManifold<3,3,3> rotate("x;-z;y","x;z;-y"); static const CompositionManifold<2,3,3,3,2,3> rotated_sphere(sphere, rotate); dimension of first manifold (sphere) = 2 but this is not equal to chart dimension of second manifold (rotate) = 3 ???
