An overview of Jadim
| The mesh | The different
files | The results
Jadim solves incompressible, unsteady
and 3-D Navier-Stokes equations with the Volum Of Fluid methods. To run
a simulation, it needs to generate a mesh with several programs. After,
paramaters concerning the fluid, the geometry or the simulation must be
filled out into some files. Concerning the results, we used Matlab to see
the presence rate of the different phases.
To generate a mesh, it is quite easy, it needs just to enter
the dimensions of a parallelepipede, the number of cells in each direction
and an angle if there is an inclinaison in the problem, in a file called
name.don (wher name is the name of the case). With th eroutine,
gener1, it creates the file name.nume which contains the coordinates
of the problem. The routine geonsm create the file name.genu
and curnsm creates name.geom which are the files of geometry
of the case. Finally, the program bord generates the file name.bord
which contains the boundary regions.
In fact, there are four files of parameters
to run a simulation:
-The first one is name.para,
where is everything concerning the calculus: timestep, number of iterations,
unsteady or steady flow etc...
Concerning the results, there are several
files, but the main ones are res.tau and uvw.res. In the
first one are the the presence rates, and you can visualize it with a small
matlab program. In uvw.res, are the different coordinates of the velocity.
-The second one is name.phys
where are stocked all the datas concerning the fluids: viscosity, volumic
mass, thermodynamic coefficients etc...
-In name.limi, you have
to enter the boundary conditions.
-It is name.datr you have
to modify if there are interfacial transfers.
-Finally, initial conditions are in name.init.
