Hi Bruce,
please have a look at GetDP's wiki, where you can find beside a detailed description of
TimeLoopAdaptive also a complete example:

Look there at Documentation --> TimeLoopAdaptive
Have a nice day!

Subject: [Getdp] Using TimeLooAdaptive with InterativeLoop to solve non-linear problems
All
Has anyone tried to construct a non-linear problem using adaptive time stepping.
My Resolution looks like :
/*
-----------------------------------------------------------------------------------------
Step 10 - Resolution of the problem
1] The resolution is setup to solve non-linear problems
*/
Resolution
{
{
Name NonLinear;
System
{
{ Name U ; NameOfFormulation ElectroThermal ; }
{ Name T ; NameOfFormulation HeatTransfer ; }
}
Operation
{
InitSolution [ T ] ; SaveSolution [ T ] ;
Generate [ U ] ; Solve [ U ]; SaveSolution [ U ] ;
TimeLoopAdaptive[ tStart, tStop, dtInit, dtMin, dtMax, Method, List[Breakpoints],
System
{
{ T, Treltol, Tabstol, LinfNorm }
{ U, Ureltol, Uabstol, LinfNorm }
}
]
{
IterativeLoop [nlMaxIter, nlEps, nlRelax]
{
GenerateJac[T]; SolveJac[T];
GenerateJac[U]; SolveJac[U];
}
SaveSolution [ T ];
SaveSolution [ U ];
}
}
}
}
// end: Resolution
And this delivers a syntax error within Gmsh.
