Subject: Instantiate MappingC1 for dim <= spacedim
X-Git-Tag: v9.6.0-rc1~443^2
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=refs%2Fpull%2F16798%2Fhead;p=dealii.git

Instantiate MappingC1 for dim <= spacedim

The mapping is not implemened for dim!=spacedim, but it is better to
get ExcNotImplemented than missing symbols.
