DEFINITION
ECCATM specifies the diffusion boundary condition code for individual edges.
REMARKS
The boundary constraint code (bcc) options for DefBCAtom and BCAtom(i) are: 1 edges are absorbing carbon from the environment 3 atom flux 4 local definition For bcc = 2, carbon absorption from environment calculations will be performed at the specified edge. For bcc = 3, the value of the atom flux should be specified with ECAFLX. For bcc = 4, the value of the edge atom flux should be specified with LOCATM or in a user routine. The user specifies both an atom flux and environmental atom diffusion in this boundary condition. Applicable object types: Elastic, Plastic, Elastoplastic, and Porous.
