Hi Sumit,

latticeU and charU are conversion factors. latticeU is the lattice velocity in m/s. The boundary functions expect lattice values, it converts such that setting latticeU on the bonudary will give you charU as physical result.
For the pressure boundary the stability problem could arise from inducing large gradients.
