    Anotace:

      Program pro numerické řešení problémů nestlačitelného proudění v 2d oblastech. Program je založen na metodě konečných prvků a používá prvky definované na nestrukturovaných sítích, s využitím několika typů konečných elementů a SUPG resp. GLS stabilizace. V programu je použita Arbitrary Lagrangian Eulerian metoda a proudění je propojeno s pohybující se strukturou (2 stupně volnosti). Program je implementován v jazyce C, byl přeložen na několika platformách (Linux,Unix,Windows) a různých typech počítačů. Program byl verifikován použitím na několik testovacích úloh.

    Anotation:

      Program for numerical solution of incompressible flow in 2d domain. The program is based on finite element method defined on unstructured triangular grids with the use of several types of mixed elements and SUPG or GLS stabilization. For the application in aeroelastic/hyroelastic problems the Arbitrary Lagrangian Eulerian mehod is used and the flow problem is coupled with the structure motion (2 degrees of freedom). The program is implemented in C language and was compiled on multiple platforms (Linux,Unix,Windows) and computers. Program was verificated on several benchmarks problems.

    Packages

    For using of the program the following packages must or can be used.
    • Mesh generation - TRIANGLE/ANGENER
    • Linear solver - UMFPACK (neccessary)
    • Graphical output - GMV/Tecplot/Matlab
    • Linear Elasticity Module - BEM ( to be included )
    • SVN - subversion system

    Getting the package

    The package is not freely accessible, it is in still development stage. If you would like to help with development, please, let me know by e-mail. You shoul install SUBVERSION and UMFPACK. Wide range of platforms (Linux, Windows, Unix, ...) is tested and works with FEMFLUID

    Personal contact is recommended in order to explain all topics included in the program.

    SVN acces

    In order to get the SVN subversion access you need the SSH DSA private key for accessing the SVN archiv. (SVN_ID_DSA_FILE) Once you have it put the following line in your profile/.bashrc file:

    SVN_SSH="ssh -l svacek -i $HOME/.ssh/SVN_ID_DSA_FILE"
    Then you can simply checkout the last version of the FEMFLUID 
    svn checkout svn+ssh://pesva.fsik.cvut.cz/SVN/femfluid/branches/YOURNAME


    IMPORTANT!
    Please, work only in your branch (named by your surname)!
    IMPORTANT!


    FEMFLUID on Windows/CYGWIN

    Download and install CYGWIN/X with GNU C compiler and OPENSSH.

    Download and install Tortoise SVN.

    Configure SVN client by adding the line to file C:\Documents and Settings\(username)\Application Data\Subversion\config 

    ssh =C:/cygwin/bin/run.exe C:/cygwin/bin/ssh.exe -i C:/cygwin/home/yourname/.ssh/SVN_ID_DSA_FILE
