+//! \brief Kernel for StressBC using the iMEM approach
+//!
+//! kernel prescribe a wall shear stress using the iMEM apprach (see, Asmuth et. al (2021), https://doi.org/10.1063/5.0065701)
+//! StressCompressible_Device couples the iMEM to the single-node interpolated bounce-back.
+//! StressBounceBackCompressible_Device couples the iMEM to a simple bounce-back.
+//! Note, that the iMEM function is currently only implemented for straight walls with z-normal and q=0.5.
+//! Other wall models could be implemented in the iMEM by replacing the formulations from Monin-Obukhov similarity theory (MOST)
+//! with other formulations, e.g., for smooth walls.
+//! iMEM so far most extensively tested with StressBounceBackCompressible_Device, but StressCompressible_Device also seems to be stable and working.

+//! \brief Kernel for StressBC using the iMEM approach
+//!
+//! kernel prescribe a wall shear stress using the iMEM apprach (see, Asmuth et. al (2021), https://doi.org/10.1063/5.0065701)
+//! StressCompressible_Device couples the iMEM to the single-node interpolated bounce-back.
+//! StressBounceBackCompressible_Device couples the iMEM to a simple bounce-back.
+//! Note, that the iMEM function is currently only implemented for straight walls with z-normal and q=0.5.
+//! Other wall models could be implemented in the iMEM by replacing the formulations from Monin-Obukhov similarity theory (MOST)
+//! with other formulations, e.g., for smooth walls.
+//! iMEM so far most extensively tested with StressBounceBackCompressible_Device, but StressCompressible_Device also seems to be stable and working.

+//! \brief Kernel for StressBC using the iMEM approach
+//!
+//! kernel prescribe a wall shear stress using the iMEM apprach (see, Asmuth et. al (2021), https://doi.org/10.1063/5.0065701)
+//! StressCompressible_Device couples the iMEM to the single-node interpolated bounce-back.
+//! StressBounceBackCompressible_Device couples the iMEM to a simple bounce-back.
+//! Note, that the iMEM function is currently only implemented for straight walls with z-normal and q=0.5.
+//! Other wall models could be implemented in the iMEM by replacing the formulations from Monin-Obukhov similarity theory (MOST)
+//! with other formulations, e.g., for smooth walls.
+//! iMEM so far most extensively tested with StressBounceBackCompressible_Device, but StressCompressible_Device also seems to be stable and working.

+//! iMEM approach (see, Asmuth et. al (2021), https://doi.org/10.1063/5.0065701)
+//! Note, that the iMEM function is currently only implemented for straight walls with z-normal and q=0.5.
+//! Other wall models could be implemented in the iMEM by replacing the formulations from Monin-Obukhov similarity theory (MOST)
+//! with other formulations, e.g., for smooth walls.
+//! iMEM so far most extensively tested with StressBounceBackCompressible_Device, but StressCompressible_Device also seems to be stable and working.

-//! \brief Kernels for StressBC using the iMEM approach
-//!
-//! Both kernels prescribe a wall shear stress using the iMEM apprach (see, Asmuth et. al (2021), https://doi.org/10.1063/5.0065701)
-//! QStressDeviceComp27 couples the iMEM to the single-node interpolated bounce-back.
-//! BBStressDevice27 couples the iMEM to a simple bounce-back.
-//! Note, that the iMEM function is currently only implemented for straight walls with z-normal and q=0.5.
-//! Other wall models could be implemented in the iMEM by replacing the formulations from Monin-Obukhov similarity theory (MOST)
-//! with other formulations, e.g., for smooth walls.
-//! iMEM so far most extensively tested with BBStressDevice27, but QStressDeviceComp27 also seems to be stable and working.
