Detailed Description
Represents a term or terms appearing in evolutionary equations.
Each EquationTerm either directly modifies quantities, or adds quantity derivatives. These terms never work directly with pairs of particles, instead they can register IDerivative that will be accumulated by the solver. EquationTerm can then access the result.

Member Function Documentation
◆ create()
Creates all quantities needed by the term using given material.
Called once for every body in the simulation.
Implemented in DensityIndependentPressureForce, HeatDiffusionEquation, ViscousStress, ConstSmoothingLength, ContinuityEquation, NavierStokesForce, SolidStressForce, PressureForce, AdaptiveSmoothingLength, StressAV, MorrisMonaghanAV, and BalsaraSwitch< AV >.
◆ finalize()
|
pure virtual |
Computes all the derivatives and/or quantity values based on accumulated derivatives.
Called every time step after derivatives are evaluated and saved to storage.
Implemented in ConstSmoothingLength, ContinuityEquation, NavierStokesForce, SolidStressForce, PressureForce, AdaptiveSmoothingLength, StressAV, and BalsaraSwitch< AV >.
◆ initialize()
|
pure virtual |
Initialize all the derivatives and/or quantity values before derivatives are computed.
Called at the beginning of every time step. Note that derivatives need not be zeroed out manually, this is already done by timestepping (for derivatives of quantities) and solver (for accumulated values).
Implemented in ConstSmoothingLength, ContinuityEquation, NavierStokesForce, SolidStressForce, PressureForce, AdaptiveSmoothingLength, StressAV, and BalsaraSwitch< AV >.
◆ setDerivatives()
|
pure virtual |
Sets derivatives required by this term.
The derivatives are then automatically evaluated by the solver, the equation term can access the result in finalize function. This function is called once for each thread at the beginning of the run.
Implemented in Tests::SingleDerivativeMaker< TDerivative >, DisplacementTerm, DensityIndependentPressureForce, XSph, SurfaceNormal, NeighbourCountTerm, HeatDiffusionEquation, SimpleDamping, ViscousStress, NaiveViscosity, CohesionTerm, ConstSmoothingLength, ContinuityEquation, NavierStokesForce, SolidStressForce, PressureForce, AdaptiveSmoothingLength, DeltaSph::VelocityDiffusion, DeltaSph::DensityDiffusion, StressAV, StandardAV, RiemannAV, MorrisMonaghanAV, ArtificialConductivity, and BalsaraSwitch< AV >.
