Class

|
newDirectionMixedFvPatchField
|
|
|
|
Description
|
|
Doubly mixed fixed value-fixed gradient boundary condition
|
|
separated into a normal and a tangential component given a
|
|
direction vector. The mixture is controlled by two separate
|
|
valueFraction coefficients in the normal and tangential direction.
