Detailed Description

DERIVED TYPE ode_opSplt: operator splitting methods for ODEs.

Choral constants for operator splitting methods for ODEs: ODE_OS_xxx, see the list.

The type ode_opsplt defines operator splitting methods for ODEs.

Addressed ODE problems (see ode_problem_mod detailed description):

• ODE_PB_SL = semilinear problem
• ODE_PB_SL_NL = semilinear problem coupled with ODE systems

An ode_opsplt method 'os' is constructed with:

os = opsplt(os_meth, l_meth, nl_meth)

• OS_meth = operator splitting method
• L_meth = one step linear ODE solver
• NL_meth = one step non-linear ODE solver

To solve an ODE with an operator splitting solver, follow the steps in ode_solver_mod.
