The key to storing time series data in a vtk file is to include the 'TIME' field in the 'FieldData' section. This field specifies the time value for the current data set. In this example, there is only one time step with a value of 1.0.

The data itself is stored in the 'POINT_DATA' section, with each variable (in this case, temperature and velocity) given its own field. The values for each variable are listed for each point in the mesh.
