i used following steps:

1) add to main solver
#include "scalarIOList.H" //add

2) add to creatFields.H

scalarIOList jump
(
IOobject(
"jump",
runTime.timeName(),
mesh,
IOobject::NO_READ,
IOobject::NO_WRITE
),
label(1.0));

3) update

jump[0] = myvalue;

4) in boundary condition i add :

const scalarIOList& jump =
db().lookupObject<scalarIOList>("jump");

but i faced following strange!!!!! error

lookup of jump from objectRegistry region0 successful
but it is not a scalarList, it is a scalarList ???????????

From function objectRegistry::lookupObject<Type>(const word&) const
in file ...../OpenFOAM-1.6.x/src/OpenFOAM/lnInclude/objectRegistryTemplates.C at line 121.

i guess its a bug
