Detailed Description

Encapsulates all physical BC's for IAMR solves.

This class is designed to contain all the information needed to specify all physical boundary conditions needed for the IAMR code. This includes BC's for velocity, pressures, scalars. While basic solid-wall BCs are coded in to this class, the idea is that for a more complicated set of physical boundary conditions (inflow, etc) a problem-dependent class will be derived from this one which will override the generic BC's in this class

virtual basicEdgeVelBC* PhysBCUtil::advectionVelBC (    )  const [virtual]
 

returns edge-centered vel BC for edge-ctrd vel (single component)

virtual void PhysBCUtil::basicCCVelBC (  DomainGhostBC &    a_newBC,

returns a single-component BC for cell-centered velocity

Reimplemented in channelBC.

virtual void PhysBCUtil::computeBoundaryDt (  Real &    a_dt,
Real    a_cfl,

this is in case the BC's have an effect on the timestep

pass in currently computed dt, along with cfl and dx. If effect of boundary conditions requires a decreased timestep, the newly reduced timestep is returned. In the default case, this just returns a_dt back; however, derived classes may actually have an effect.
