Prescribed Chemical Potential
The
Prescribed Chemical Potential
node adds a Dirichlet boundary condition where the chemical potential is prescribed. Only boundaries adjacent to domains where a
Chemical Potential
node has been assigned are allowed.
Prescribed Chemical Potential
Individually specify the value of the chemical potential for each species. Select the checkbox for the
Species
to specify its value, and then enter a value or expression in the corresponding field.
