Detailed Description

template<unsigned DIM>
class FineCoarseMeshPair< DIM >

Class for a pair of meshes, one fine, one coarse, which should cover the same domain (or very nearly match). This class is used to set up interpolation information from one mesh to the other.

At the moment the functionality is very much based on the four information-transfers required in cardiac electromechanics problems

(i) Calcium (or voltage) to induce deformation: FINE(electrics) MESH NODEs ---> COARSE(mechanics) MESH QUADRATURE POINTS (ii) Deformation gradient (assume constant in any coarse element) for altering conductivities: COARSE ELEMENTS ---> FINE ELEMENTS (iii) Deformation gradient/fibre-stretch (assume constant in any coarse element) for cell-model stretch activated channels COARSE ELEMENTS ---> FINE NODES (iv) Voltage visualisation on coarse mesh FINE NODES ---> COARSE NODES

The usage of this class for each of these tasks is:

(i) FINE NODEs ---> COARSE QUADRATURE POINTS FineCoarseMeshPair<2> mesh_pair(fine_mesh,coarse_mesh); mesh_pair.SetUpBoxesOnFineMesh(); mesh_pair.ComputeFineElementsAndWeightsForCoarseQuadPoints(quad_rule, false); mesh_pair.rGetElementsAndWeights(); (ii) COARSE ELEMENTS ---> FINE ELEMENTS FineCoarseMeshPair<2> mesh_pair(fine_mesh,coarse_mesh); mesh_pair.SetUpBoxesOnCoarseMesh(); mesh_pair.ComputeCoarseElementsForFineElementCentroids(); mesh_pair.rGetCoarseElementsForFineElementCentroids(); (iii) COARSE ELEMENTS ---> FINE NODES FineCoarseMeshPair<2> mesh_pair(fine_mesh,coarse_mesh); mesh_pair.SetUpBoxesOnCoarseMesh(); mesh_pair.ComputeCoarseElementsForFineNodes(); mesh_pair.rGetCoarseElementsForFineNodes();

Note the following should not be done at the same time as (i), as the results are stored in the same place (iv) FINE NODES ---> COARSE NODES FineCoarseMeshPair<2> mesh_pair(fine_mesh,coarse_mesh); mesh_pair.SetUpBoxesOnFineMesh(); mesh_pair.ComputeFineElementsAndWeightsForCoarseNodes(false); mesh_pair.rGetElementsAndWeights();

unsigned FineCoarseMeshPair< DIM >::ComputeCoarseElementForGivenPoint ( ChastePoint< DIM > &  rPoint,
bool  safeMode,
unsigned  boxForThisPoint 
) [inline, private]

For a given point, compute the containing element in the coarse mesh (returned).

Parameters:
rPoint The point
safeMode See documentation in ComputeCoarseElementsForFineNodes
boxForThisPoint The box in coarse box collection containing this point
Todo:
: could possibly merge with ComputeFineElementAndWeightForGivenPoint(). Differences between the methods are: the other method uses fine mesh and fine mesh box, computes weights as well (and sets the element and weight in the vec), rather than returning the element, and that method saves information in mStatisticsCounters.

void FineCoarseMeshPair< DIM >::ComputeCoarseElementsForFineElementCentroids ( bool  safeMode  )  [inline]

Compute the element in the coarse mesh that each fine element centroid is contained in (or nearest to). Call SetUpBoxesOnCoarseMesh() before, and rGetCoarseElementsForFineElementCentroids() afterwards.

Parameters:
safeMode This method uses the elements in the boxes to guess which element a point is in. If a point is in none of these elements, then if safeMode==true, it will then search the whole mesh. If safeMode==false it will assume immediately the point isn't in the coarse mesh at all. safeMode=false is will far more efficient with big meshes. It should be fine to use safeMode=false if SetUpBoxesOnFineMesh() is called with default values.

Set up the containing (fine) elements and corresponding weights for all the quadrature points in the coarse mesh. Call GetElementsAndWeights() after calling this with the index of the quad point (=the index of the quad point in a QuadraturePointsGroup= the index if the quad points were listed by looping over all the element and then looping over all the quad points).

Parameters:
rQuadRule The quadrature rule, used to determine the number of quadrature points per element.
safeMode This method uses the elements in the boxes to guess which element a quad point is in.
