The PDE solvers do not have parameters which can be changed by the user with the exception of the MacCormack solver which has a switch for flux-corrected transport which stabilizes adjacent cell oscillations and setting it on (check the box) may improve a solution.
The PDE solvers are:
- LSFEA
- MacCormack
- TOMS731
- Comments or Questions?
LSFEA: Lagrangian Sliding Fluid Element Algorithm
No user adjustable parameters available in JSim implementation. Decreasing spatial and temporal step size may be useful.
MacCormack: Explicit 2nd order accurate in space and time
The MacCormack solver which has a switch for flux-corrected transport (FCT) which stabilizes adjacent cell oscillations and setting it on (check the box) may improve a solution. Decreasing spatial and temporal step size may be useful.
TOMS 731: Transactions of Mathematical Software Algorithm 731 (a moving-grid interface for systems of one-dimensional time-dependent partial differential equations)
No user adjustable parameters available in JSim implementation. Decreasing spatial and temporal step size may be useful.
