XFoil

I am totally excited to find CAE Linux. As a recently graduated engineer, I am impressed to find so much valuable software packaged together into one convenient operating system!

XFoil/AVL on CAELinux 2010 are missing a library file: "xfoil: error while loading shared libraries: libg2c.so.0: cannot open shared object file: No such file or directory"

I have played with installing libf2c, gfortran, etc... but to no avail.

I am a beginner and I use caelinux 2009 (I bought the DVD). first I used java foil but for what i try to find ( lift and drag) avl is more successful for low angle of attack;
There is ,for Computationnal Fluid Dynamics, better think with open foam 1.7 but more complicated.For me
After installation you will automatically switch to ubuntu 10.04 without problem .

I am aware of OpenFOAM. AVL and XFOIL Have the advantage that they are potential flow applications which (at least for me) is great for preliminary design.

They are fast because they simplify the problem, which allows for lots of design iterations early.

I agree OpenFOAM is better, but only in that it is more accurate (and SLOW compared to AVL and XFOIL). Thus, I would like to use OpenFOAM as a last step rather than the first.

If anyone has more experience with linux, and compiling old-school fortran, perhaps they can shed some light on the library error from above. Thank you, it would be appreciated.

I have heard in the past the XFoil and AVL don't compile well unless you use the intel fortran compiler. Could this perhaps be an intel fortan library?

You can also try with QFLR5, it's OSS too and includes the code of XFoil for foil analysis and two other solvers for wing/wing-fuselage configurations, one is a lifting surface approach (same as AVL) and the other is a panel method. It's programmed in either C or C++, cannot recall well, but the results are good.
In case you wish to try MatLab codes that can be ported to Octave with not so much effort, you can use Pablo for foils and Tornado for wing configurations. Pablo is somewhat limited compared to XFoil and JavaFoil.
