Detailed Description

template<typename YGRID>
class Dune::Composites::baseGridModel< YGRID >

structuredGridModel class.

structuredGridModel provides a base class for 3D structure grid models built on using Dune::YaspGrid and Dune::GeometryGrid. The class provides all default functions for definition of a user defined model.

Constructor & Destructor Documentation

baseGridModel()

template<typename YGRID >

Dune::Composites::baseGridModel< YGRID >::baseGridModel ( Dune::MPIHelper &  helper_, bool  GenEO = false  )

inline

The main constructor.

Constructor of structuredGridModel, requiring only the MPI Helper defined by dune

References Dune::Composites::baseGridModel< YGRID >::isParallel, Dune::Composites::baseGridModel< YGRID >::setUp_Required, Dune::Composites::baseGridModel< YGRID >::solver_verb, and Dune::Composites::baseGridModel< YGRID >::stress_Plot_ascii.

Member Function Documentation

isDirichlet()

template<typename YGRID >

bool Dune::Composites::baseGridModel< YGRID >::isDirichlet ( FieldVec &  x, int  dof  )

inline

A function which returns whether a point x lies on a Dirichlet boundary for the degree of freedom dof. If the function returns false it assumes this node is on the Neumann boundary or an interior node.

LayerCake()

template<typename YGRID >

void Dune::Composites::baseGridModel< YGRID >::LayerCake ( )

inline

A member taking which constructs the base layered laminate in untransformed coordinates.

LayerCake is a function which defines a flat three-dimensional tensor product grid and the grid's properties (e.g. periodicity); building $\hat \Omega := [0,L] \times [0,W] \times [0,T]$, where $L$, $W$ and $T$ are the length, width and thickness of the laminate This function provides default values which can be overwritten by defining your own class

References Dune::Composites::baseGridModel< YGRID >::nel, and Dune::Composites::baseGridModel< YGRID >::periodic.

LayerCakeFromFile()

template<typename YGRID >

void Dune::Composites::baseGridModel< YGRID >::LayerCakeFromFile ( string  pathToCsv )

inline

Function to read LayerCake from File.

The function provides an interface to read all the information needed to set up a LayerCake, i.e. size of tensor product grid, periodicity information, etc. from a .csv file. A user can also define the grid, layering and region properties manually.

References Dune::Composites::baseGridModel< YGRID >::periodic, and Dune::Composites::baseGridModel< YGRID >::R.

meshRatio()

template<typename YGRID >

std::vector< double > Dune::Composites::baseGridModel< YGRID >::meshRatio ( int  N, double  scaling, int  direction  )

inline

Function defining mesh grading.

This is a helper function that defines a graded mesh in the format used by ABAQUS
