| 1## libCEED: Navier-Stokes Example 2 3This page provides a description of the Navier-Stokes example for the libCEED library, based on PETSc. 4PETSc v3.17 or a development version of PETSc at commit 0e95d842 or later is required. 5 6The Navier-Stokes problem solves the compressible Navier-Stokes equations in three dimensions using an explicit time integration. 7The state variables are mass density, momentum density, and energy density. 8 --- 640 unchanged lines hidden (view full) --- 649 - 0 650 - 651 652* - `-sgs_model_dd_parameter_dir` 653 - Path to directory with data-driven model parameters (weights, biases, etc.) 654 - `./dd_sgs_parameters` 655 - string 656 | 1## libCEED: Navier-Stokes Example 2 3This page provides a description of the Navier-Stokes example for the libCEED library, based on PETSc. 4PETSc v3.17 or a development version of PETSc at commit 0e95d842 or later is required. 5 6The Navier-Stokes problem solves the compressible Navier-Stokes equations in three dimensions using an explicit time integration. 7The state variables are mass density, momentum density, and energy density. 8 --- 640 unchanged lines hidden (view full) --- 649 - 0 650 - 651 652* - `-sgs_model_dd_parameter_dir` 653 - Path to directory with data-driven model parameters (weights, biases, etc.) 654 - `./dd_sgs_parameters` 655 - string 656 |
