Initial Solution Step

The actual analysis is carried out incrementally in several load steps until the overall prescribed load is reached.

The program requires setting the initial load step only.

This parameter represents the ratio between the load applied in a given load step to the overall prescribed load. Depending on the course of iteration this parameter is adaptively adjusted.

The default setting assumes 25% of the total prescribed load. Similarly to what we have already mentioned it holds that increasing the solution complexity from the nonlinear response point of view requires reduction of this parameter. However, in case of elastic response this parameter can be set equal to 1, which corresponds to the solution of a given problem in one load step.
