Detailed Description

template<typename VariablesTag, typename MeshTag, typename InverseJacobianTag, typename DerivTags = typename VariablesTag::type::tags_list, typename InertialCoordsTag = void>
struct Tags::DerivCompute< VariablesTag, MeshTag, InverseJacobianTag, DerivTags, InertialCoordsTag >

Compute the spatial derivatives of tags in a Variables.

Computes the spatial derivatives of the Tensors in the Variables represented by VariablesTag in the frame mapped to by InverseJacobianTag. To only take the derivatives of a subset of these Tensors you can set the DerivTags template parameter. It takes a tmpl::list of the desired tags and defaults to the full tags_list of the Variables.

For an executable that does not allow a Cartoon basis, the last parameter, InertialCoordsTag, should not be passed.

This tag may be retrieved via Tags::Variables<db::wrap_tags_in<deriv, DerivTags, Dim, deriv_frame>.

The documentation for this struct was generated from the following file:
