Load Step Selection
This subordinate form appears whenever the Load Step Selection button is selected on the main Analysis form. This form is used to select and order the Load Steps that will be analyzed for the Marc job. At least one Load Step must be selected and appear in the Selected Load Steps list box. Once a load step or load steps have been selected, you may submit the job by pressing the Apply button on the main Analysis application form.
 
Note:  
A Default Static Step is always available for linear or nonlinear static analysis. It is also automatically selected for you by default. It is therefore unnecessary to select a Load Step if the default is adequate. Other solution types or multiple step analysis requires that you create additional Load Steps. See Load Step Creation, 233 for information on how to create Load Steps. An error will be issues if you select Load Steps that are not valid for the set analysis type: Structural, Thermal, or Coupled.
Multiphysics Selection
In th e Coupled analysis type, you can specify coupling between different types of physical phenomenon. The default is thermal-mechanical or structural-thermal coupling, in which case you do not need to open this form at all. If you wish to do purely structural, or purley thermal, or electrostatic or electrodynamic-thermal coupling, then you must select the coupled physics types in this form.
