varied vector component boundary conditions
Does anyone know if there is already a defined boundary conditions for vectors which allows you to assign different types/values for each vector component? For example:
Suppose vector U=(u,v,w), I would need to define:
Thanks for ur help
as we know the temperature of of engine cylinder temperature is different in each point and it is difficult to set a temperature to each point . I have got an Abacus CAD file of the studying engine and it includes the temperature values in each point . I wamma to know how can I set temperature to each point . for example for point (1,4,0) T1=100'C , (3,0,2) T2=102'C , ..... tnx in advance
i will appreciate alot I need your experience
reza, i guess your looking for sth like this
hope it helps!
But what do you mean exactly ?
Boundary Condition or some function (source term) ?
There is several way to do this.
I personally opt for modifying the original source code. There is easy way to set BC and any value or functions you want in the source code and the re-compile it again.
Some example is here:
/////////////added to chancge bc (in time, in space)
label inletPatchID = mesh.boundaryMesh().findPatchID("in");
const fvsPatchVectorField& centre = mesh.Cf().boundaryField()[inletPatchID];
const fvsPatchVectorField& normal = mesh.Sf().boundaryField()[inletPatchID];
fvPatchVectorField& uu = U.boundaryField()[inletPatchID];
This code make your BC on the patch "in" time and space dependent.
tt -- is some function of space.
In general you can read any data to your openFoam variables, the same way as you would do in C or C++.
But of course, there are some already done procedures in OF to do this, just check more carefully all examples which come with OF installation.
