Analysis Tasks
An analysis task is a package of work for the solver. Thus we can have a static analysis task, a modal analysis task, etc. Each analysis task has one or more analysis case(s). The distinction is that the cases corresponds to result sets and define items such as loading (in the static case) while the task describes what the solver has to do. So for example the task will determine which solver has to be used, what solution option in that solver is required and other control parameters such as the number of iterations, convergence tolerances etc.
