| void seldofinit | ( | ) |
The function initializes selected dofs used for the arclength method controling.
The function solves system of nonlinear algebraic equations by the arc-length method. This method was modified to reach the given value lambdar of the lambda parameter. lambdar value is reached with required error errl. Only one right hand side vector is supported with respect to nonlinearity and absence of superposition. Proportional vector grows until the nial number of steps is reached.
