How to compile PHITS-UDM

Hint

Before compiling PHITS-UDM, it is recommended to check if the original PHITS can be compiled. (Ref: How to compile the original version of PHITS)

  • Download the PHITS-UDM (phits-udm-****.zip) from here.

(If you have already downloaded the file, proceed to the next step.)

  • Assume the path to the PHITS folder is as follows:

PhitsFolder=/Users/you/phits330A/phits

  • Extract phits-udm-********.zip to obtain the phits-udm folder.

phits-udm
 |- diff/
 |- examples/
 |- main.py
 |- sample-code-1/
 |- udm_Parameter.f

  • Copy the expansion folder phits-udm to the PHITS folder.

cp -r <Your Download Folder>/phits-udm ${PhitsFolder}

  • Move to phits-udm.

cd ${PhitsFolder}/phits-udm/

  • Run the Python script.

python main.py

If successful, a src-udm/ folder will be created in the PHITS folder and will look like this,

!! Completed !!

(If you see an error, please let me know. [PHITS Forum / Contact])

  • Copy the PHITS-UDM sample codes in phits-udm/sample-code-1 to src-udm/

cp sample-code-1/* ../src-udm/.

  • Move to src-udm/

cd ${PhitsFolder}/src-udm/

  • Open makefile in src-udm/ and specify the available compilers in the ENVFLAGS flag variable on line 8.

Example) Compiling with Intel Fortran on Linux

ENVFLAGS = LinIfort

Example) For Linux gfortran

ENVFLAGS = LinGfort

Example) For Mac gfortran

ENVFLAGS = MacGfort

  • If necessary, change the compiler to be used by default if you choose ENVFLAGS specified above.

Example) If using Mac gfortran, modify line 243 of the makefile as follows

(Before) FC        = gfortran-mp-4.8
(After ) FC        = gfortran

  • Type make (in src-udm)

make

  • If the compilation is successful, an executable file for PHITS-UDM is generated in the PHITS folder.

Example) For Mac and intel fortran

ls ${PhitsFolder}/phits_MacIfort-udm

Once the executable file is generated, proceed to the following section:

If it fails, check if the PHITS original can be compiled according to [How to compile the original version of PHITS] below.

Let me know if you can compile the original PHITS but not PHITS-UDM. [Contact]].

The following compilers have been confirmed to work:

  • ifort (Intel Fortran for Linux and Mac)

  • gfotran (Linux. gcc version 8.3.0 (GCC))

  • gfotran (MacOS. gcc version 10.3.0 (Homebrew GCC 10.3.0))



How to compile the original version of PHITS

  • Assume the path to the PHITS folder is as follows:

PhitsFolder=/Users/you/phits330A/phits/

  • Move to src folder

cd ${PhitsFolder}/src

  • Open makefile and specify the available compilers in the ENVFLAGS flag variable on line 8.

Example) Compiling with Intel Fortran on Linux

ENVFLAGS = LinIfort

Example) For Linux gfortran

ENVFLAGS = LinGfort

Example) For Mac gfortran

ENVFLAGS = MacGfort

  • If necessary, change the compiler to be used by default if you choose ENVFLAGS specified above.

Example) If using Mac gfortran, modify line 243 of the makefile as follows

(Before) FC        = gfortran-mp-4.8
(After ) FC        = gfortran

  • Type make (in src/ folder)

cd ${PhitsFolder}/src
make

  • If the compilation is successful, an executable file is generated.

Example) For Mac and intel fortran

${PhitsFolder}/phits_MacIfort
