Velocity extension for the computation of the Laplacian of the velocity.
For the Laplacian of the velocity, the normmal velocity is taken from the mirroring interpolated value (SSM), while the tangential velocity is taken directly from the body motion (U0M).
In the thesis of Benjamin Bouscasse the tangential velocity is asymetrically extended (ASM). However it is producing unphysical results.
Herein the density is also got from the mirroring interpolated value (SSM)
- Parameters
-
imove Moving flags. - imove > 0 for regular fluid particles.
- imove = 0 for sensors.
- imove < 0 for boundary elements/particles.
associations Mirroring particles. normal Normal \( \mathbf{n} \). gp_rho Interpolated density in the mirrored position \( \rho \). gp_u Interpolated velocity in the mirrored position \( \mathbf{u} \). rho Density \( \rho \). u Velocity \( \mathbf{u} \). N Number of particles.
