4.2 Review of the Analysis Form
The Analysis form appears when you select Analysis from the main form. To run an analysis, or to create an NASTRAN input file, select Analyze as the Action on the Analysis form. Other forms brought up by the Analysis form are used to define translation parameters, solution types, solution parameters, output requests, and load cases. These forms are described on the following pages. For further information, see The Analysis Form (p. 8) in the MSC.Patran Reference Manual.
 
Analysis Form
This form appears when you select Analysis from the main menu. When preparing for an analysis run, select Analyze as the Action.
The following table outlines the selections for the Analyze action.
Object
Method
Entire Model
Full Run
Check Run
Analysis Deck
Model Only
Current Group
Full Run
Check Run
Analysis Deck
Model Only
Existing Deck
Full Run
The Object indicates which part of the model is to be analyzed. There are three choices for thermal analysis: Entire Model, Current Group, and Existing Deck.
Entire Model
Indicates that the whole model is to be analyzed.
Current Group
Indicates that only part of the model is to be analyzed. To do this, you create a group of that part, confirm that it is the current group, then select Current Group as the Object. For more information, see The Group Menu (p. 270) in the Patran Reference Manual.
Existing Deck
Means that you wish simply to submit an existing input file to MD Nastran. To form the input filename, Patran appends the suffix “.bdf” to the jobname appearing in the Job Name listbox. This file must reside in the current directory.
The Method indicates how far the translation is to be taken.The methods are as follow:
Full Run
Is the selected type if an Analysis Deck translation is performed, and the resulting input file is submitted to MD Nastran for complete analysis.
Check Run
Is the selected type if an Analysis Deck translation is performed, and the resulting input file is submitted to MD Nastran for a check run only.
Analysis Deck
Is the selected type if the Model Deck translation is performed, plus all load case, analysis type and analysis parameter data are translated. A complete input file, ready for MD Nastran, will be generated.
Model Only
Is the selected type if a Bulk Data file is created that contains only the model data including node, element, coordinate frame, element property, material property, and loads and boundary conditions data. The translation stops at that point.
