Function File: vtkWrite( FileName , mesh Th, U, names)

To write a mesh Th and values U in a VTK file.

Parameters

FileName : a VTK file name (string)

mesh Th : a 2D or 3D mesh

U : an array of cells which contains all the values to save in VTK file,

names : an array of cells which contains all the names of the values to save in the VTK file.

Examples 

  % Saving scalar values to a VTK file
  Th = GetMeshOpt('sphere-1-10.mesh', 'format', 'medit');
  U = cos(Th.q(1,:).^2+Th.q(2,:).^2+Th.q(3,:).^2);
  V = cos(Th.q(1,:).^2+Th.q(2,:).^2+Th.q(3,:).^2);
  vtkWrite('sample01.vtk', Th, {U',V'}, {'u','v'});

  % Saving vector values to a VTK file
  U{1} = Th.q(1,:).^2+Th.q(2,:).^2+Th.q(3,:).^2;
  U{2} = cos(U{1});
  U{3} = sin(U{1});
  vtkWrite('sample02.vtk', Th, {[U{1},U{2},U{3}]}, {'U'});
