Hi, I'm searching for a comprehensive opensource CFD package. I've found OpenFOAM, Openflower and ADFC. Can anyone suggest anything better? I'm mainly interested in parallel solution of incompressible turbulent flows. Thanks Ashfaque

I've downloaded OpenFOAM, but I'm having problems to compile it. Does anybody knows how to get wmake for linux? I have only the gnu make, and it seems that wmake is avaiable only for windows. Is it right?

This is shipped with OpenFOAM.

Basically, you should follow these steps (make sure you do as much sanity checking after each step as you possibly can because this is not standard GNU build):

1) unpack the general pack into ~/OpenFOAM. You will get something like:

/home/coyote/hjasak/OpenFOAM/OpenFOAM-1.1

2) Unpack the auxiliary tools into the directory:

~/OpenFOAM/linux

You definitely need the gcc compiler, some post processing (always comes in handy) and java (if your native version is different):

coyote*375-> cd ../linux

/home/coyote/hjasak/OpenFOAM/linux

coyote*376-> ls

total 117M

drwxr-x--- 16 hjasak foam 4.0K 2004-10-06 13:42 cmake-2.0.3

drwxr-x--- 4 hjasak foam 4.0K 2004-04-27 09:11 dx-4.3.2

drwxr-x--- 9 hjasak foam 4.0K 2005-01-06 05:52 gcc-3.4.3

drwxr-x--- 8 hjasak foam 4.0K 2004-12-13 17:38 gdb-6.2.1

drwxr-x--- 9 hjasak foam 4.0K 2004-07-06 07:52 j2sdk1.4.2_0

drwxr-x--- 5 hjasak foam 4.0K 2005-03-14 06:37 paraview-1.8.5

3) copy

~/OpenFOAM/OpenFOAM-1.1/.OpenFOAM-1.1/

into your home directory and add the following line into your .cshrc:

source $HOME/.OpenFOAM-1.1/cshrc

(there is an equivalent for bash if you really must)

4) source ~/.cshrc and do some checking. For example:

coyote*378-> which g++

/home/coyote/hjasak/OpenFOAM/linux/gcc-3.4.3/bin/g++

coyote*379-> which wmake

/home/coyote/hjasak/OpenFOAM/OpenFOAM-1.1/wmake/wmake

5) Now we're close. Try running foamInstallationTest

/home/coyote/hjasak/OpenFOAM/OpenFOAM-1.1/bin/foamInstallationTest

and analyze the reported problems (if any).

Once you're happy, do the following: foam ; ./Allwmake

coyote*381-> foam

/home/coyote/hjasak/OpenFOAM/OpenFOAM-1.1

coyote*382-> ./Allwmake

and the whole thing should build.

There is some build documentation in the release + a forum for questions of this kind - have a look at:

Good luck,

Hrv
