Hermes::Hermes2D::MeshData Class Reference

Class to stored 2d mesh parameters. The MeshData class organizes all the necessary data structures required to store information in the input mesh file. All variables are stored internally as a mapping between strings and a list of strings. Symbolic expressions are not supported for variables. The variables are stored in a vector of strings. This is true for single-valued variables, lists and list of lists. The contents of the variables are thus accessed differently depending on their contents. More...

Detailed Description

Class to stored 2d mesh parameters. The MeshData class organizes all the necessary data structures required to store information in the input mesh file. All variables are stored internally as a mapping between strings and a list of strings. Symbolic expressions are not supported for variables. The variables are stored in a vector of strings. This is true for single-valued variables, lists and list of lists. The contents of the variables are thus accessed differently depending on their contents.
