Detailed Description

Usage

To output a .bp file, simply call the following routine:

call notus_adios_output_grids_and_fields()

This routine will output all the variables contained in the print_list variable. It will also output variables that cannot be contained in the print_list such as the MOF quadrilateral grid or refined grids and their associated fields.

How to add a new kind of variable to output?

ADIOS requires to define the variables to output before writting them. To add a new kind of variable to output, two routines must be created. One routine to declare the variable to ADIOS. It should defines the size of the data in bytes, the dimension and the rank of the array to write. A second routine to write the data in the .bp file.

For a simple example, see notus_adios_define_rectilinear_grid and notus_adios_write_rectilinear_grid. For a complex example that involve the definition of an unstructured grid, see notus_adios_define_mof_polygons and notus_adios_write_mof_polygons.
