mapFields command not found

When working through the Cavity tutorial, invoking the command mapFields yields the error message command not found.

~/OpenFOAM/OpenFOAM-v1606+$ mapFields -help mapFields: command not found

Recheck the installation log. It should be available.

@Prashant: Keep in mind that official installation instructions don't explain how to create said installation log: http://www.openfoam.com/code/build-guide.php ;)

@Radon: Run Allwmake as follows:

• When using bash: ./Allwmake > log.make 2>&1
• When using tcsh: ./Allwmake >& log.make

All of the textual output that comes from Allwmake will be sent into the file log.make, which is essentially the installation log that Prashant was referring to.

Thanks Bruno

Here is the installation log that I made after the installation. I am not sure what to look for and it seems like it may have skipped making everything from scratch.

log.make

Line 161 states you didn't setup FFTW, leading to failure of randomProcess library.

This leads to incomplete compilation.

Perhaps, try setting etc/config.sh/FFTW and rebuild.

Thanks for your response. I am a novice at Linux. I followed the installation directions on http://openfoam.com/download/install-source.php. Please tell me how to set etc/config.sh/FFTW.

Hi Eric, two options: either install fftw on your system, or edit the etc/config.sh/FFTW file to have this type of content:

fftw_version=fftw-3.3.4
export FFTW_ARCH_PATH=$WM_THIRD_PARTY_DIR/platforms/$WM_ARCH$WM_COMPILER/$fftw_version

And make sure that you have the fftw-3.3.4 unpacked under $WM_THIRD_PARTY_DIR. The Third-Party Allwmake should now find the configuration and the rest of the OpenFOAM build should work.

Mentioned in issue #357 (closed)

It is working now. The solutions you suggested did not work. It was my fault. I did not see the System Requirements. After I ran the System Requirements commands, the mapFields now works. Thanks for your time.

Status changed to closed

PS. I had to uninstall OpenFoam and re-install after the System Requirements were implemented.
