Version 1.6: Example Applications
The SURC solvers are global-timestep, consistent mass-matrix CFD solvers whose formulation is based on the Charactersitic-Based split method, which is mostly the work of O.C. Zienkievicz and P. Nithiarasu.
The SURC solvers are not yet adapted to problems with inhomogenous pressure boundary conditions. The work is still heavily in progress, so please do not consider this production code. The findings regarding upwind stabilization that were made with the SURC4 solver, are sure to manifest in changes in the cfd_c class of Animath 1.7.
Some Images that were generated with the SURC2 solver
Flow-direction-indicating particles released from the driving wall
The problem consists of a linear-elastic unit cube with a Young's modulus of 1MPa and compressibility of nu = 0.45, that is exposed to a homogeneous stress-field of (500, 0.0, 0.0, 0.0, 0.0, 0.0) Pa.
The deviatroic setup differs in that the RHS has no divergence, i.e the pressure of 500/3 is subtracted from the 3 first components of the stress.
