Time history analysis

This solver (as opposed to dynamic analysis realized in linear solvers based on spectrum analysis methods) enables the user to perform time history analysis of nonlinear deformed structures, e.g. structures with one-way restraints, physically nonlinear systems that have σ-ε relations in the shape of Prandtl diagrams.

Direct integration method is realized. With this solver the user could simulate behaviour of nonlinear structures in time.

This solver is mainly used for research purposes.
