S11-1PAT301, Section 11, October 2003 SECTION 11 ANALYSIS SETUP

S11-2PAT301, Section 11, October 2003

S11-3PAT301, Section 11, October 2003 ANALYSIS SETUP n Analysis form automatically customized to user-selected analysis code n Analysis Parameters are selectable from this form n Optionally can submit and monitor status of the analysis jobs across the network n For MSC.Nastran this form can also be used to read an existing bulk data file into the MSC.Patran database (MSC.Nastran files can also be read using File/Import)

S11-4PAT301, Section 11, October 2003 SETTING UP THE ANALYSIS n The comments below are specific to MSC.Nastran. However, there are similar features for other solvers, e.g. MSC.Marc. n The analysis model may be prepared for u Entire model (in the MSC.Patran database) u Selected group (model in a single group), e.g. group_1 u Existing deck (model file) u Restart (from a prior run) u Interactive (modify file.DBALL)

S11-5PAT301, Section 11, October 2003 n Select Translation Parameters… to specify the output format, solver version, etc. SETTING UP THE ANALYSIS (Cont.)

S11-6PAT301, Section 11, October 2003 SETTING UP THE ANALYSIS (Cont.) n Select Solution Type… to specify the type of solver run, e.g. linear static

S11-7PAT301, Section 11, October 2003 n Direct text input allows the insertion, into the MSC.Nastran input file that is created upon translation out of MSC.Patran, of additional data that needs to be used to define the model. SETTING UP THE ANALYSIS (Cont.)

S11-8PAT301, Section 11, October 2003 SETTING UP THE ANALYSIS (Cont.) n Create subcases under Subcases… u Select an available subcase, or create a subcase u Select available load cases u Specify subcase parameter values u Select entities to be output, i.e. displacements, stresses

S11-9PAT301, Section 11, October 2003 SETTING UP THE ANALYSIS (Cont.) n Select the subcases already defined using Subcase Select… n The run-ready file can be submitted direcly to MSC.Nastran from within MSC.Patran, or the file can be submitted outside of MSC.Patran

S11-10PAT301, Section 11, October 2003 RESULTS TRANSLATION INTO MSC.PATRAN n Results can be accessed by Attach XDB, Read Output2, Attach MASTER, or Attach T16/T19 n Either the results or model or both can be accessed u Result Entities: stresses, displacements u Model Data: nodes, elements u Both: both model and results

S11-11PAT301, Section 11, October 2003 READING A MSC.NASTRAN BULK DATA FILE n Existing MSC.Nastran bulk data files can be read into MSC.Patran to verify and update models that were not created inside MSC.Patran n The MSC.Nastran bulk data file reader is used to translate the model into MSC.Patran n Any statement not recognized will be optionally displayed in a window by area; file management section, executive section, case control section, or bulk data section n Numbering offsets can be set to none, automatic, or manually input for each entity type
