template<typename PRM>
class Dune::PDELab::DGNavierStokesVelVecFEM< PRM >
A local operator for solving the Navier-Stokes equations using a DG discretization and a vector-valued finite element map for the velocity grid function space.
- Template Parameters
-
| PRM | Parameter class for this local operator. |
◆ DGNavierStokesVelVecFEM()
Constructor.
- Parameters
-
| [in] | _prm | Parameter class for this local operator |
| [in] | _superintegration_order | This number will be added to the order of quadrature in every integration. It is only needed, when one of the parameters (e.g rho, mu) is not constant or the mappings from the reference elements to the cells are nonlinear. Boundary conditions are assumed to have the same order as the corresponding finite element. |
◆ getStage()
get current stage
- Returns
- The current stage number previously set by preStage().
◆ getTime()
get current time
- Returns
- The time previously set by setTime().
◆ postStep()
to be called once at the end of each time step
- Note
- With the OneStepMethod and the ExplicitOneStepMetod, for reasons unknown this is only called for temporal but not for spatial local operators. With the MultiStepMethod this is called for all local operators.
◆ preStage()
to be called once before each stage
- Parameters
-
| time | Time of the stage |
| r | Number of the stage, r ∈ [1, nstages] inclusive, where nstages is the number of stage in the step given in the previous call to preStep() |
- Note
- For ExplicitOneStepMethod the time given here for stage 1 may be incorrect, since the time step size is only finally determined after the first stage has been assembled.
-
For the MultiStepMethod, this is called once after preStep() with r=1.
◆ preStep()
to be called once before each time step
- Parameters
-
| time | Time at beginning of the step. |
| dt | Size of time step. |
| stages | Number of stages to do in the step. For the MultiStepMethod this is always 1. |
- Note
- For ExplicitOneStepMethod the dt given here may be incorrect, since the time step size is only finally determined after the first stage has been assembled.
-
For the MultiStepMethod the number of stages is given as
- Since there are no times of evaluation in the middle of the step, a multi-step method is similar to a one step method with one stage.
◆ setTime()
set time for subsequent evaluation
This method set the time for subsequent calls to the alpha_*(), lambda_*(), jacobian_*() and jacobian_apply_*() methods.
- Note
- For ExplicitOneStepMethod the time given here in the first stage may be incorrect, since the time step size is only finally determined after the first stage has been assembled.
◆ suggestTimestep()
to be called after stage 1
- Note
- Only used by the ExplicitOneStepMethod.
This may be called on the spatial local operator in the case of an explicit one step scheme. It is called after stage 1 has been assembled (so the time given to preStep() may not apply anymore in this case). All the alpha_*() and lambda_*() methods should have been called, so they are a good place to generate the information returned here.
