DVOLF DVOLF Iobj, Numel, Nphase 1 f1, f2, f3, fn OPERAND DESCRIPTION DEFAULT Iobj Object number NONE Numel Number of Element NONE Nphase Number of Materials NONE DEFINITION DVOLF specifies the change in volume fraction of all the different phases that resulted from the transformation during each time step. DVOLF of each phase is initially set to zero in a simulation. REMARKS DVOLF is determined by for each step where f is the volume fraction of a particular phase. DVOLF is used in calculating the latent heat due to transformation and the change in volume of the object. DVOLF can be invaluable in determining the progress of a transformation and aid the user in deciding whether to increase or decrease the time step for a particular transformation. Applicable Simulation Modules: Microstructure Applicable Simulation Modes: Transformation Applicable Object Types: ALL except rigid ECAFLX ECAFLX Object1, Ndata, Default Num(1), node1(1) node2(1) node3(1) node4(1) Flux(1) : : : Num(Ndata), node1(Ndata) node2(Ndata) node3(Ndata) node4(Ndata) Flux(Ndata) OPERAND DESCRIPTION DEFAULT Object Object number None Ndata Number of face data sets None Default Default value for edge based atom flux 0.0 Num(i) ith data pair None node1(i) 1 st node defining face i node2(i) 2 nd node defining face i node3(i) 3 rd node defining face i node4(i) 4 th node defining face i Flux(i) Distributed atom flux of ith data pair 0.0 DEFINITION ECAFLX specifies the distributed atom heat flux to be applied to individual faces. REMARKS Distributed atom flux is defined as atom per unit time per unit area. The atom flux is assumed to be constant over the edge it is defined over. In order to activate atom flux, the faces must be specified using the keyword ECCATM with a boundary condition code of 3. Atom flux may be specified as a function of time with keyword ECATFN. Applicable object types: Rigid, Elastic, Plastic, Elastoplastic, Porous ECATFN ECATFN Object, Ndata, Default Num(1), node1(1) node2(1) node3(1) node4(1) BCfuncNum(1) : : : Num(Ndata), node1(Ndata) node2(Ndata) node3(Ndata) node4(Ndata) BCfuncNum(Ndata) OPERAND DESCRIPTION DEFAULT Object Object Number None Ndata Number of face constraint data sets None Default Default value for function number 0 Num(i) ith data set None node1(i) 1 st node defining face i None node2(i) 2 nd node defining face i None node3(i) 3 rd node defining face i node4(i) 4 th node defining face i BCfuncNum(i) Function type for diffusion boundary constraint in ith data None set DEFINITION ECATFN specifies whether a atom face boundary condition function is defined as a function or through a user subroutine. REMARKS The function type (Ftype) options are: < 0 user routine number > 0 function number (specified in BCCFNC) The user should be aware that the face definition function shares the function structure with the nodal boundary condition function keyword (BCCFNC).

REMARKS The boundary constraint code (bcc) options for DefBCAtom and BCAtom(i) are 1. faces 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 face. For bcc = 3, the value of the atom flux should be specified with ECAFLX . For bcc = 4, the value of the face 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.

REMARKS The face boundary constraint code (bcc) options are 2: face pressure 9: local definition For ecc = 2, the value of the nodal traction should be specified with keyword ECPRES. Only normal pressure can only be applied to faces. The keyword ECDEFN is used to specify if the face values are specified as a constant, a function of time or by a user routine (Note: The user routine option is not available in the NT versions of 2D). For ecc = 9, the local boundary conditions are specified with LOCDEF .
