I am calc a partical transport problem with cfx4.4. I dont know how to set the boundary condition of wall, that is, how can I specify a coefficient of restitution for a specific wall and particle size. Is it in the commond file or user fortran?

It is only possible in the command file to set a global restitutions coeffecient. If you want one that depends on, speed, angle, size etc. you would need user fortran.
