class | TestFineCoarseMeshPair |
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.
The functionality is based on the four information-transfers required in cardiac electro-mechanics problems
The usage of this class for each of these tasks is:
To see progression for any of these methods, run test from the command line with '-mesh_pair_verbose' as a command line parameter

void FineCoarseMeshPair< DIM >::ComputeCoarseElementsForFineElementCentroids | ( | bool | safeMode | ) |
Compute the element in the coarse mesh that each fine element centroid is contained in (or nearest to). Call SetUpBoxesOnCoarseMesh() before, and rGetCoarseElementsForFineElementCentroids() afterwards.
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. |

Print information about the number of points found in the searched mesh. What the points are and which mesh was searched depends on whichever of the main Compute methods was last called.
If ComputeFineElementsAndWeightsForCoarseQuadPoints() or ComputeFineElementsAndWeightsForCoarseNodes() were last called, the indices of the points that were not found to be contained in the searched mesh are also printed, along with the weights for that point in the nearest element (which indicates how far from the mesh the points are).
