How can I change initial pressure ?
 

I am definitely a novice for the OpenFoam so sorry if my problem is so basic.

I wanted to change the initial pressure condition but it went wrong.
I altered shockTube tutorials, especially the pressure condition, pressure information is stated in the shockTube/0/p file and it is 1D originally however, I want to set the initial pressure condition to 2D. Probably, I haven't rewritten all of what is required, I think. The things I did are stated below.



:(1. in the shockTube/0/p file I rewrote as below

FoamFile
{
version 2.0;
format ascii;
class vectorField;
location "0";
object p;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

dimensions [1 -1 -2 0 0 0 0];

internalField nonuniform List<vector>
1000
(
(900000 100000)
...
...
(900000 1000)
);

boundaryField
{
sides
{
type zeroGradient;
}
empty
{
type empty;
}
}



:(2 in the p.org file
I rewrote class from volScalarField to vectorField

What should I do ???
I would appreciate it if anyone could help me.
THANK YOU;)
