The procedure to compile UDF
s via command line is briefly described on
the makefile_nt.udf
file, quoting:
Usage:
- Change file name
'makefile_nt.udf'
to'makefile'
.- Place the makefile file in the target dir.
- Place the helper file
'user_nt.udf'
in same directory.- Edit
user_nt.udf
file.- Execute an
'nmake'
(no arguments needed).
To use these instructions, first the directory folder for the compilation must be created and the files placed in the correct folders.
❗ The newer versions of Fluent are always executed in parallel version. If serial execution is selected on the launcher, a parallel run with just one node is created!
For all versions, the procedure for compilation is the same. So a single script to perform the compilation was developed. The steps taken on this procedure are detailed below.
The directory three for the generation of the UDF
library is shown
here, a simple description of the content of each folder is presented.
library-name/ -> The name that identifies the library on Fluent.
├── src/ -> Contains copies of source files (.h and .c).
└── win64|lin64/ -> Architecture
├── 2d/ ┌
├── 2d_host/ │ Different possible configurations for the given
├── 2d_node/ │ architecture.
├── 2ddp/ │
├── 2ddp_host/ │ Versions without the 'dp' component are single
├── 2ddp_node/ │ precision, while the ones containing it are
├── 3d/ │ double precision.
├── 3d_host/ │
├── 3d_node/ │ Versions 'host' have code to run in the host
├── 3ddp/ │ node of a parallel run and the 'node' have the

└── 3ddp_node/ └
This directory tree is generated automatically by the compilation script
under the build
directory.
All source code files (.h and .c files) must be copied into the
directory library-name/src/
. The files makefile_nt.udf
must be
copied to all version directories and renamed to makefile
. The final
copy needed is to place the user_nt.udf
also inside every version
folder.
The file user_nt.udf
must be edited to define the version to be
compiled, the
set FLUENT_INC=%AWP_ROOT190%\fluent
set PATH=%PATH%;%FLUENT_INC%\ntbin\win64
