function ConvertHDF5_VTK(hdf_file, vtk_prefix, varargin)
|
|
% ConvertHDF5_VTK(hdf_file, vtk_prefix, varargin)
|
|
%
|
|
% Convert openEMS field data stored in the given hdf5 file to a vtk file.
|
|
%
|
|
% arguments:
|
|
% hdf_file: source hdf5 file
|
|
% vtk_prefix: output vtk files prefix
|
|
%
|
|
% optional arguments:
|
|
% 'TD_Dump': activate dump for time-domain data (default is off)
|
|
% 'FD_Dump': activate dump for frequency-domain data (default is on)
|
|
% 'NumPhase': number of phase to dump frequency domain data animation
|
|
% (default is 36 --> 10°)
|
|
% 'FieldName': field name written to vtk, e.g. 'E-Field'
|
|
%
|
|
% example:
|
|
% % read time-domian data from hdf5, perform dft and dump as vtk
|
|
% ConvertHDF5_VTK('Et.h5','Ef','NumPhase',18,'Frequency',1e9)
|
|
