Analysis Wizard : Envelopes

The use of analysis envelopes is described in the Step-by-Step Guide.

Description

Enter the envelope description here, using the syntax of combination case descriptions.

1D Element Envelope Cases

Select how many analysis cases to generate for 1D element results. Choose from:

  • Worst along element – generate one pair of analysis cases for each result type, corresponding to the position (as specified in 1D element results) with the greatest result value.
  • Per node – generate two pairs of analysis cases for each result type, corresponding to node positions 1 and 2.

1D Element Results

Opens the 1D Element Results dialog box for the specification of the positions along 1D elements at which displacements and forces are to be calculated.

2D Element Envelope Cases

Select how many analysis cases to generate for 2D element results. Choose from:

  • Worst in element – generate one pair of analysis cases for each result type, corresponding to the position (node or centre) with the greatest result value.
  • Centre only – generate one pair of analysis cases for each result type, corresponding to the result value at the centre of each element.
  • Per node and centre – generate up to nine pairs of analysis cases for each result type, corresponding to each node position and the centre of each element.

Tree Control

Select which results to generate envelopes for by ticking the boxes. Each nodal result type generates one pair of analysis cases; the number of cases for each element result type depends on the element envelope case settings.
