Hello to all,
I found this explanation to read data from file to set the initial condition

2.2.10 The #include and #inputMode directives
For example, let us say a user wishes to set an initial value of pressure once to be used as the internal field and initial value at a boundary. We could create a file, e.g. named initialConditions, which contains the following entries:

    pressure 1e+05; 
    #inputMode merge
In order to use this pressure for both the internal and initial boundary fields, the user would simply include the following macro substitutions in the pressure field file p:

    #include "initialConditions" 
    internalField uniform $pressure; 
    boundaryField 
    { 
        patch1 
        { 
            type fixedValue; 
            value $internalField; 
        } 
    }
This is a fairly trivial example that simply demonstrates how this functionality works. However, the functionality can be used in many, more powerful ways particularly as a means of generalising case data to suit the user’s needs. For example, if a user has a set of cases that require the same RAS turbulence model settings, a single file can be created with those settings which is simply included in the turbulenceProperties file of each case. Macro substitutions can extend well beyond a single value so that, for example, sets of boundary conditions can be predefined and called by a single macro. The extent to which such functionality can be used is almost endless.

How can i modify these code to read a nonuniform vecotr field at my boundary? I want to set a non uniform field for the velocity boundary condition



Thanks for help
