FFV-C Frontflow / violet Cartesian

OUTLINE

Frontflow/violet Cartesian is a three-dimensional unsteady incompressible thermal flow simulator on a Cartesian grid system. This solver is designed so as to assist practical design in industry fields by powerful voxel based approach and to achieve higher parallel performance on massively parallel computers.

How to build

Build

$ export FFVC_HOME=/hogehoge
$ mkdir build
$ cd build
$ cmake [options] ..
$ make
$ sudo make install

Options

-D INSTALL_DIR= Install_directory

Specify the directory that this library will be installed. Built library is installed at install_directory/lib and the header files are placed at install_directory/include.

-D enable_OPENMP= {yes | no}

This option makes OpenMP directives effect. Default is yes.

-D with_MPI= {yes | no}

If you use an MPI library, specify with_MPI=yes (default).

-D real_type= {float | double}

Specify the type of floating point. If this option is omitted, the default is float.

-D with_TP= Installed_Directory

Specify the directory path that TextParser is installed.

-D with_PM= Installed_Directory

Specify the directory path that PMlib is installed.

-D with_PL= Installed_Directory

Specify the directory path that Polylib is installed.

-D with_CPM= Installed_Directory

Specify the directory path that CPMlib is installed.

-D with_CDM= Installed_Directory

Specify the directory path that CDMlib is installed.

-D with_PAPI= Installed_Directory

Specify the directory path that PAPI is installed.

Configure Examples

$ export FFVC_HOME=hogehoge

In following examples, assuming that TextParser, PMlib, Polylib, CPMlib, and CDMlib are installed under the FFVC_HOME directory. If not, please specify applicable directory paths.

INTEL/GNU compiler

Note of FLOP COUNT

The number of floating operations in a loop is estimated by the value measured on the K computer.

Comment of precision of Fortran

For example, the -CcdRR8 option for fortran preprocessor convert variables, functions, and constants higher precision version in source code. Thus, functions in source code is described by floating version.
