Hi everyone,


I am completly new to SOWFA, OpenFOAM and also linux and thus sticking to installation guides provided.


I tried to install SOWFA with OpenFOAM 2.4.x and OpenFAST as stated in https://github.com/NREL/SOWFA/blob/master/README.SOWFA


In the readme the link to the OpenFOAM installation https://github.com/OpenFOAM/OpenFOAM-2.4.x is brocken for download and installation information.
Therefore I installed OpenFOAM according to https://openfoamwiki.net/index.php/I...M-2.4.x/Ubuntu for Ubunutu 14.04. and OpenFAST according to the readme on github.


Both OpenFOAM and OpenFAST are working just fine. Nevertheless trying to install/compile SOWFA I get different errors.


On step 2 in the SOWFA readme it was said to adapt the .bash_profile file. I did this recognizing the originaly set path were given for installation of OpenFOAM in ~/OpenFOAM/$USER-$OpenFOAM_VERSION path, while the installation according to the link above ended in the path ~/OpenFOAM/OpenFOAM-$OpenFOAM_VERSIO. I thought I adapted it right and tried a lot of different things (too much to list all of them) but none of them seem to work.


I do not have to stick to any Versions except of using OpenFAST (not FAST8.16 or similar). Right now I treid following settings:
VirtualBox
Ubuntu 14.04
OpenFOAM 2.4.x
SOWFA as given in the link above
OpenFAST


Is there anyone using the same settings or can you post your versions and a corresponding link (I found other version suggestions in older posts, but the referring links were brocken and it was not possible to find them elsewhere)?


Thanks a lot in advance

Hi Morli,

I know the thread is old but I have suffered a similar plight so I thought I should put something together to help others who have struggled with this, especially those new to OF and Linux like myself. So just a disclaimer this if for people new to the software looking to install on local machine. The following are based on a Ubuntu 18.04 operating system.

#------------------------------------------------------------------------------------------------------------------#

Setting up SOWFA.

1) Install OpenFOAM-2.4.0 (or 2.4.x)

file structure $HOME/OpenFOAM

/OpenFOAM-2.4.0

/ThirdParty-2.4.0

2)

cd ~/OpenFOAM

3)

mkdir $USER-2.4.0 && cd $USER-2.4.0

new file structure $HOME/OpenFOAM

/OpenFOAM-2.4.0

/ThirdParty-2.4.0

/$USER-2.4.0

4)

git clone https://github.com/NREL/SOWFA.git

5)

mv NREL-SOWFA-<2fd1c71> SOWFA-2.4.0 && cd SOWFA-2.4.0

note the <version> of SOWFA could be different if NREL has updated it

6) edit file .bash_profile to:

#--------------------------

		# .bash_profile

		# Get the aliases and functions
		if [ -f ~/.bashrc ]; then
			. ~/.bashrc
		fi

		# SOWFA-2.4.0
		SOWFA-2.4.0()
		{
		  export inst_loc=$HOME/OpenFOAM
		  #export spack_loc=$HOME

		  #echo "Purging and loading modules..."
		  #module purge
		  #module use $spack_loc/spack/share/spack/modules/linux-centos7-x86_64
		  #module load gcc-4.8.5-gcc-4.8.5-nkqvx2b
		  #module load openmpi-1.10.7-gcc-4.8.5-qu7mrny
		  #module load cgal-4.12-gcc-4.8.5-vd4qb7j
		  #module load boost-1.69.0-gcc-4.8.5-52cfbc4
		  #module load mpfr-3.1.6-gcc-4.8.5-kflyoj7
		  #module load readline-7.0-gcc-4.8.5-b4z2xcj
		  #module load scotch-6.0.6-gcc-4.8.5-3xkg4i7
		  #module load flex-2.6.4-gcc-4.8.5-htapbeu
		  #module load gmp-6.1.2-gcc-4.8.5-6bsovvk
		  #module list

		   # Unset OpenFOAM environment variables.
		   if [ -z "$FOAM_INST_DIR" ]; then
		      echo "Nothing to unset..."
		   else
		      echo "     *Unsetting OpenFOAM environment variables..."
		      . $FOAM_INST_DIR/OpenFOAM-$OPENFOAM_VERSION/etc/config/unset.sh
		   fi

		   # Set the OpenFOAM version and installation directory
		   export OPENFOAM_VERSION=2.4.0
		   export OPENFOAM_NAME=OpenFOAM-$OPENFOAM_VERSION
		   export FOAM_INST_DIR=$inst_loc
		   export WM_PROJECT_USER_DIR=$HOME/OpenFOAM/$USER-$OPENFOAM_VERSION/SOWFA-$OPENFOAM_VERSION

		   foamDotFile=$FOAM_INST_DIR/$OPENFOAM_NAME/etc/bashrc
		   if [ -f $foamDotFile ] ; then
		      echo "Sourcing $foamDotFile..."
		      source $foamDotFile
		   fi

		   export WM_NCOMPPROCS=8 # change this to your number of cores
		   export WM_COLOURS="white blue green cyan red magenta yellow"

		   alias tut='cd /home/$USER/OpenFOAM/$OPENFOAM_NAME/tutorials'

		   export SOWFA_DIR=$FOAM_INST_DIR/$USER-$OPENFOAM_VERSION/SOWFA-$OPENFOAM_VERSION
		   export OPENFAST_DIR=~/OpenFAST/openfast/install # if you want to couple OpenFAST with SOWFA this needs changing to where your openfast install is
		   export HDF5_DIR=${where HDF5 is}					                               
                    	
		   
		   export LD_LIBRARY_PATH=$SOWFA_DIR/lib/$WM_OPTIONS:$OPENFAST_DIR/lib:$LD_LIBRARY_PATH
		   export PATH=$SOWFA_DIR/applications/bin/$WM_OPTIONS:$PATH
		}

#--------------------------

7) Source editted bash_profile

 . ~/OpenFOAM/$USER-2.4.0/SOWFA-2.4.0/.bash_profile; SOWFA-2.4.0

8)

./Allwclean

9)

./Allwmake

10)

cd

12) add line to bashrc (or similar) so the command SOWFA will load SOWFA

echo "alias SOWFA='source $HOME/OpenFOAM/$USER-2.4.0/SOWFA-2.4.0/.bash_profile; SOWFA-2.4.0'" >> ~/.bashrc

Check it has compiled correctly by testing the ABL Solver

13)

SOWFA

14)

cd ~/OpenFOAM/$USER-$OPENFOAM_VERSION/SOWFA-$OPENFOAM_VERSION/exampleCases

15)

cp -r example.ABL.flatTerrain.neutral/ TEST_ABLSolver && cd TEST_ABLSolver

16) edit file runscript.preprocessor
comment out lines 13, 79, 80 (Just the OF version variable and the sourcing lines)

17) edit file runscript.solve.1
comment out lines 8, 9, 10, 12 (Sourcing lines and PBS variable for running on a cluster)
change variable "cores" to how many cores you have (line 14)

18) edit setUp file
change variables "nx", "ny" & "nz" to 30, 30 & 10 respectively (lines 16-18)

# note the above will give poor results this is just to check the solver runs

change variable "nCores" to your number of cores (line 24)
change the variable "decompOrder" to what is suitable for your hardware (line 26)

# for example if nCores is 8 decompOrder could be (2 2 2) 2*2*2=8

19)

 ./runscript.preprocess

20)

 ./runscript.solve.1

Hope this is useful to folks.

Hi,
I'm trying to install the SOWFA, but I don't have these two folders (.bash_profile, .gitignore) in my SOWFA Folder.
I used ubuntu 14.04
How can i add this two folder in my SOWFA folder?

Best Regards

[CallumG]

Hi vahid

just to ckeck that the two files you mentioned are hidden files so first ensure you are viewing hidden files too in your explorer.

With regards to the .gitignore that is a github file and not really important, however both are available here:

https://github.com/NREL/SOWFA

All the best,
Callum

Hi,
I installed Openfoam and SOWFA in my Ubuntu 16.04, and run them completely, but Tecplot isn't install in my Ubuntu, can anyone help me?

Best Regards

If I have installed OpenFOAM-6 from Openfoam.org, and it is present in /opt/openfoam6, can I not change the files in .bash_profile file?

Also, I have cloned the git of SOWFA within /opt/openfoam6 and am trying to change the .bashrc files. However I am getting an error meshPlanes.H could not be found. Is this because I have the wrong files for Openfoam or SOWFA?
