Prescribed Phase Field
The
Prescribed Phase Field
node adds a condition where the phase field variables are prescribed in the geometric entity selected (domain, boundary, edge, or point).
Prescribed Phase Field
If there is only one phase field variable, enter its prescribed value,
ϕ
0
.
If there are two or more phase field variables, select the corresponding check box for those phase fields to be prescribed and enter their values
ϕ
0,
k
.
