device_constrain_mixed_bc Module Reference

Device wrappers for basis-aware mixed boundary-condition constraint kernels. These routines operate on a resolved mixed-node mask together with a local orthonormal basis stored as nodewise normal and tangent vectors. They are used to impose homogeneous or prescribed constraints on vector fields in the local (n, t1, t2) basis on device backends.
