From: Wolfgang Bangerth Date: Fri, 21 Aug 2015 02:11:21 +0000 (-0500) Subject: Make the type of normal vectors a Tensor. X-Git-Tag: v8.4.0-rc2~565^2 X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=refs%2Fpull%2F1408%2Fhead;p=dealii.git Make the type of normal vectors a Tensor. As discussed in #496, normal vectors are currently returned by FEValues as Point objects, but since they are differential vectors, the correct data type should be Tensor<1,dim>. This patch implements the solution discussed in #496 by * changing the return type of FEValues::normal_vector() * deprecating FEValues::get_normal_vectors() * introducing FEValues::get_all_normal_vectors() that returns a vector of tensors. The old get_normal_vectors() function was deprecated. In order to make it work, I also had to change the return type from a reference to a straight array. This array may be bound to a reference in many places in user codes, but the style we have used everywhere is to make these reference variables very localized in scope and so I don't foresee any problems. --- diff --git a/doc/news/changes.h b/doc/news/changes.h index dc04d369f4..86dd14786f 100644 --- a/doc/news/changes.h +++ b/doc/news/changes.h @@ -38,6 +38,23 @@ inconvenience this causes.

    + +
  1. Changed: FEValues::normal_vector() for historical reasons returned a + value of type Point, though a normal vector is more adequately described + as a Tensor@<1,dim@>. Many similar cases were already clarified in deal.II + 8.3. The current case has now also been changed: FEValues::normal_vector() + now returns a Tensor, rather than a Point. +
    + In a similar spirit, the FEValues::get_normal_vectors() function that + still returns a vector of Points has been deprecated and a new function, + FEValues::get_all_normal_vectors(), that returns a vector of tensors, + has been added. This was necessary since there is no way to change the + return type of the existing function in a backward compatible way. The + old function will be removed in the next version, and the new function + will then be renamed to the old name. +
