IMPEXP_DOLFIN Import/export grid in FEniCS/Dolfin XML format.

[ GRID ] = IMPEXP_DOLFIN( FILE_NAME, MODE, DATA, USE_MESHFCN, FID ) Import or export of a FEniCS/Dolfin (ASCII .xml) grid and data format. FILE_NAME is a string specifying the (root) file name to process. MODE can either be a string indicating import (no boundary reconstruction), import_bdr (boundary reconstruction with gridbdr), or export. For export, DATA can be either a full fea struct or just the grid struct. USE_MESHFCN is a boolean flag to write subdomain numbers in a mesh function instead of the (default) domain field. A GRID struct is output when importing FID is an optional log file handle for message output (negative for gui output or empty for no output).

  1) Export and re-import of a unit square with a hole grid.

  grid1 = quad2tri(holegrid());
  impexp_hdf5( 'featool-fenics-mesh.xml', 'export', grid1 )
  grid2 = impexp_hdf5( 'featool-fenics-mesh.h5', 'import' )
  subplot(1,2,1), plotgrid(grid1), title('grid1')
  subplot(1,2,2), plotgrid(grid2), title('grid2')
  is_ok = gridcheck(grid2) == 0
