Parameters

[in] e Reference to used EigenProblemSolver instance

◆ build() [3/3]

void build ( TimeStepping & s )

Build the linear system of equations.

Before using this function, one must have properly selected appropriate options for:

The choice of a steady state or transient analysis. By default, the analysis is stationary
In the case of transient analysis, the choice of a time integration scheme and a lumped or consistent capacity matrix. If transient analysis is chosen, the lumped capacity matrix option is chosen by default, and the implicit Euler scheme is used by default for time integration.
