- add a new module FORCING to handle forcing source terms, e.g. for
turbulence driving;
- implement initial versions of init_forcing() and clear_forcing()
subroutines;
- add compilation flag FORCING and use it during compilation process in
makefile;
- add a new module RANDOM which handles initialization and generation
of different type random number distributions;
- include the module in the compilation process;
- initialize the random generator from driver;
Rewritten boundaries allow for a proper handling boundaries between
blocks at different refinement levels. Prolongation and restriction of
the boundaries are improved now.
Rewritten interpolation for prolongation and restriction.
References to the variable indices are assigned more properly.
A new 'mpitools' module has been added. This module contains subroutines
to initialize, deinitialize and handle MPI communication. This initial
version can now initialize and deinitialize parallelization. It does not
support full parallelization yet.
Now we can control the levels of refinement/derefinement criterion from
the config file. The bounds of the domains are stored in the HDF5 files
from now.
The function to calculate the maximum speed in the block has been added.
This function is used to determine the maximum speed globally, which is
next used to estimate the next time step.
A new parameter to control the time interval between writing data has
been added. Also the condition to check if data should be written has
been added in the main loop.
A new module for the time integration has been added. This module
contains a set of subroutines to perform one step time integration of
each leaf block using 2nd order Runge-Kutta method. More methods can be
added later. Time 't', timestep 'dt' and iteration 'n' have been moved
to this module as well.
A new module called 'timer' has been added. The purpose of this module
is to handle the execution timers of the program or its subtasks, like
initialization, data writing, evolution, etc.
The final summary of the times spent on different task has been added
as well.
I replaced the pointer 'pfirst' pointing to the first element of the
list of blocks with 'plist'. I improved formatting of the informations
printed during the initial mesh generation.
Initial implementation of subroutine 'write_data' to store all data.
This subroutine initially will support only HDF5 file format. The
block structure of the file is not decided yet.
Implemented the generation of initial blocks in N-configuration with
proper ataching to the list, pointer, neighbors and bounds
initialization, as well as the initial problem setup. Two new files has
been added: mesh.F90 - hadling the adaptive mesh structure, and
problem.F90 - handling the problem initialization.
Config module takes care of the configuration file 'config.in'. It
reads the file line by line, parsing each line and extracting the name
and value of parameter. Then it substitutes the parameter with a new
value.
Error module handles error, warning and informative messages. So far it
only prints information on the screen.
There is some improvments for comments formating as well.
Block structure has been implemented. Blocks contain pointers to the next
and previous blocks. This easily allows to create block lists. Two
functions are implemented, one for creating initial structure of blocks
with lists, and the second for destroying all blocks from the list.
File 'blocks.F90' has been added to makefile too.
