C++ API

Function File: fpl_vtk_raw_write_field (basename, mesh, nodedata, celldata)

Output data field in binary serial XML-VTK UnstructuredGrid format.

basename is a string containing the base-name of the (vtu) file where the data will be saved.

mesh is a PDE-tool like mesh, like the ones generated by the "msh" package.

nodedata and celldata are (Ndata x 2) cell arrays containing respectively <PointData> and <CellData> representing scalars or vectors:

  • - *data{:,1} = variable data;
  • - *data{:,2} = variable names;

Example: 

%% generate msh1, node centered field nc1, cell centered field cc1
fpl_vtk_raw_write_field ("example", msh1, {nc1, "temperature"}, {cc1, "density"});
%% generate msh2, node centered field nc2
fpl_vtk_raw_write_field ("example", msh2, {nc2, "temperature"}, {});

The difference between fpl_vtk_write_field and fpl_vtk_raw_write_field is that the former saves data in ASCII format while the latter uses raw binary format. To save data in b64-encoded binary format use fpl_vtk_b64_write_field.
