    Deactivated loads are still visible in PLAXIS Output
    It is possible for projects to have various loads being deactivated in a calculation phase. When checking PLAXIS Output results, it can happen that the visualization of the load is still visible even though the value of the load is set to zero. The load arrows may still be visible as the load is not yet fully deactivated, as ΣΜstage is not yet equal to one (1) and not all out-of-balance is solved for this calculation phase.

    How to activate a dynamic load
    In PLAXIS 2D and 3D, providing that the dynamic module is available, a dynamic (i.e., time-dependent) load can be defined by assigning a dynamic multiplier to the dynamic component of a load. As detailed later, the dynamic component of a given load is independent of its static component.

    How to prescribe a dynamic displacement
    In PLAXIS 2D and 3D, a dynamic displacement can be assigned to any cartesian component of a given prescribed displacement to define its evolution with time. As detailed below, the dynamic displacement is only prescribed to the model when both static and dynamic components of displacement are activated.

    How to setup the number of steps stored in PLAXIS Input
    In PLAXIS Input, the default behaviour is to store only the last calculation step of each phase. The option to set the Max number of steps stored can be found in Phases window, under the Numerical control parameters.

    How to setup tied degrees of freedom
    For a dynamics analysis, the user can choose several boundary conditions: Viscous, Free field, tied degrees of freedom and no specific boundary (None). With the option Tied degrees of freedom, the calculation will connect the nodes at the left and right model boundaries such that the corresponding nodes will undergo exactly the same displacements. This option may be chosen to model e.g. a one-dimensional shear column in order to perform a site response analysis.
