WitrynaChoosing between implicit and explicit analysis. For many analyses it is clear whether Abaqus/Standard or Abaqus/Explicit should be used. For example, as demonstrated in Nonlinearity, Abaqus/Standard is more efficient for solving smooth nonlinear problems; on the other hand, Abaqus/Explicit is the clear choice for a wave propagation analysis. When we talk about implicit or explicit in fea, we talk about the algorithm that is used for time incrementation. In both cases, the state of the model is calculated at multiple points in time and the new state is calculated based on the old state. With an explicit algorithm the new state can be calculated … Zobacz więcej The computational cost of a single explicit increment is small; all information needed is available and the calculation is straight-forward and fast. … Zobacz więcej Abaqus/Standard, the implicit solver, can solve for static equilibrium: the state where the sum of the forces is zero. It is also possible to include dynamic effects. If dynamic effects … Zobacz więcej Abaqus/Standard is more beneficial for problems that are slow and relatively linear, while Abaqus/Explicit is more beneficial for problems that are fast and very non-linear. … Zobacz więcej Contact can be included in both Abaqus/Standard and Abaqus/Explicit.

WitrynaThe implicit method is not sensitive to such small elements. Since the explicit time step size depends on the material properties, a nearly incompressible material will also significantly reduce the stable time step. The compressibility of the material can be increased in explicit analysis to achieve a more acceptable solution time.
