VOLFS VOLFN 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 VOLFN specifies the volume fraction limit of a phase in an element of an object. VOLFN is only stored in the database at the beginning of a new phase transformation, ex. Austenite  Pearlite or Austenite  Martensite. The intent of VOLFN is to assure that the volume fraction amount transformed from Austenite  Pearlite does not exceed the volume fraction of Austenite prior to transformation. REMARKS Example of implementation of VOLFN A: Austenite P: Pearlite B: Bainite M: Martensite Step 1 A: 1 P:0 B:0 M:0 (VOLFN stored into database) A  P Step 2 A: 0.9 P:0.1 B:0 M:0 Step 3 A:0.8 P:0.2 B:0 M:0 (VOLFN stored into database) A  B (phase P complete) Step 4 A:0.7 P:0.2 B:0.1 M:0 It should be noted that VOLFC is different than VOLFN in that VOLFC stores the volume fraction of the phases every step. Typically, the user will only be concerned with inputting volume fractions for VOLFN at the beginning of the simulation.
