+* G+Smo (perpendicular-flap-vertex-gismo). This solver includes both linear and nonlinear versions of the Newmark time integrator for time-dependent structural problems. The linear version iterates using a constant stiffness matrix. The nonlinear version iterates using an updated Jacobian matrix to account for material or geometric nonlinearity. By default, the solver runs in linear mode. To switch to nonlinear mode, add `--nonlinear` as option in `run.sh`.
