Detailed Description

Elmer: 3D flow calculator -- kernel functions and data storage.

This is the place where we keep the global_data_3D structure and the service functions that provide access to it.

Function Documentation

long allocate_arrays_for_blocks (  void   )

Calls the C-module array allocation function, once for each block. Returns total number of bytes allocated if successful, or -1 if any of the allocation requests fail.

int first_block (  void   )

Returns the index of the first block for this process. This is a convenience function so that we can code loops over block the same whether for the MPI code of for the shared-memory code.

int impose_chemistry_timestep_for_block (  struct block_data_3D *  bp, double  dt )

Impose a specified chemistry timestep over the whole block. Parameters: bp  : pointer to a block_data_3D structure dt  : the specified timestep

int impose_global_parameters_3D (  struct global_data_3D *  G, struct block_data_3D *  bp )

Copy some of the global parameter values into the block parameters such as the time step, etc. It is presumed that the flow states have all been set (before setting block parameters). Parameters: G  : pointer to the global_data structure A  : pointer to the block_data structure Version: 17-Aug-04 : bring over from mb_init.c

int impose_global_timestep_for_block (  struct block_data_3D *  bp, double  dt )

Copy the global time-step values into the block. Parameters: bp  : pointer to a block_data_3D structure dt  : the specified timestep

int initialize_global_parameters (  void   )

Set sensible default parameters in elmer.py (not used in elmer_main.c). These may be overwritten later.

int last_block (  void   )

Returns the index of the last block for this process. This is a convenience function so that we can code loops over block the same whether for the MPI code of for the shared-memory code.

int set_block_range (  int  first, int  last )

Set the limits for the range of block indices. Be sure to do this immediately after establishing the actual number of blocks in the calculation and, for MPI jobs, that this number matches the number of processors.
