Detailed Description

Read an MPAS netCDF file.

This program reads an MPAS netCDF data file to allow paraview to display a dual-grid sphere or latlon projection. Also allows display of primal-grid sphere. The variables that have time dim are available to ParaView.

Assume all variables are of interest if they have dims (Time, nCells|nVertices, nVertLevels, [nTracers]) Assume no more than 100 vars each for cell and point data Does not deal with edge data.

When using this reader, it is important that you remember to do the following: 1. When changing a selected variable, remember to select it also in the drop down box to "color by". It doesn't color by that variable automatically. 2. When selecting multilayer sphere view, make layer thickness around 100,000. 3. When selecting multilayer lat/lon view, make layer thickness around 10. 4. Always click the -Z orientation after making a switch from lat/lon to sphere, from single to multilayer or changing thickness. 5. Be conservative on the number of changes you make before hitting Apply, since there may be bugs in this reader. Just make one change and then hit Apply.

Member Function Documentation

static vtkMPASReader* vtkMPASReader::New ( ) [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkUnstructuredGridAlgorithm.

virtual const char* vtkMPASReader::GetClassName ( ) [virtual]

Reimplemented from vtkUnstructuredGridAlgorithm.

static int vtkMPASReader::IsTypeOf ( const char * name ) [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkUnstructuredGridAlgorithm.

virtual int vtkMPASReader::IsA ( const char * name ) [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkUnstructuredGridAlgorithm.

static vtkMPASReader* vtkMPASReader::SafeDownCast ( vtkObject * o ) [static]

void vtkMPASReader::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)			`[virtual]`
