Analysis Manager

An Analysis is a collection of model configuration, analysis loadcase and analysis set-up selections that completely specifies the assembly definition for a particular loadcase simulation event.

The Analysis Manager is invoked by clicking the icon.



Figure 1.
The top-left section of the dialog shows a complete list of analysis and offers checkboxes to show or hide the analysis set-up.


Figure 2.

Any Analysis is defined as a combination of model configuration, analysis loadcase and analysis set-up.

Model Configuration

Already defined model configurations are listed and can be selected for creating an analysis.


Figure 3.

Analysis Loadcase

This section is used to create, edit or delete an analysis loadcase.


Figure 4.
Analysis loadcase definition is a combination of loadcase and states for modules and connections. The loadcase definition and selection of states for modules and connections can be specific to a particular configuration or independent of it.


Figure 5.
The following solution types are available for loadcase definition.
Frequency Response
This functionality generates the solver deck for user-defined loadcase templates supporting the automated generation of diagnostic requests.
Normal modes
Generates normal modes for the solver deck.
Full deck TPL
Generates the solver deck for user-defined loadcase templates.
Process manager generated loadcase entities
Generates the solver deck for the process manager generated loadcase templates.
Solver deck
Frequency Response
If you select Frequency Response as the solution type, you are presented with the following sub-tasks:
Loadcase type selection
Select a loadcase type for analysis.
General
Select pre-defined loadcases in terms of templates or solver decks.
Standard
Allows processing of advanced loadcases for:
  • Road inputs
  • Powertrain Loads
  • Driveline Imbalance
  • Wheel Imbalance
  • Spindle Loads
Select Analysis Frequencies
Define the frequency range of analysis.
Normal Modes Extraction
Contains an option to specify normal mode extraction parameters for modal frequency analysis.
Loading point selection
You can define the loading points using the template or solver deck. Click Apply when you are done.
Loading strength definition
Loading strength information from the TPL files or the solver deck gets loaded here. There is an option to review the loading strength and to edit/modify the loading strength. To assign a new loading strength click the icon. Loading strength can be defined from external CSV, UNV or the solver deck.


Figure 6.

You can select module states and connection states depending on the loadcase definition.

Analysis Setup

This section is used to create, edit or delete an analysis setup.


Figure 7.
Analysis setup definition is a combination of module setup and diagnostic setup. The setup can be specific to a particular configuration or independent of it. This setup also allows you to specify the type of analysis: Regular, Multiple Sample Analysis (MSA) and Single Sample Analysis (SSA).


Figure 8.
You can select the module representation type for a particular analysis setup.


Figure 9.
Select analysis type
Define the analysis type, modal or direct.
Response Selection
Select response type and entities, and output file format.
Diagnostic options selection
Request diagnostic options, such as modal/panel participation, grid participation, auto TPA, ODS and element energy for concerned frequencies using PEAKOUT and OFREQ.
Global damping selection
Define the global structural and fluid damping. There is an option to skip the structure damping and define only the fluid damping.
Parameter selection
Define additional parameters. You can enter the PARAM name and the default value will automatically be populated. These defined parameters get written out in the solver deck.

Tuning Sets

You have the option to select and review the tuning sets from the list for quick modification studies. The tuning sets defined in the tuning sets manager are available for selection. The FE entities related to selected tuning sets are created and written in the Main solver deck.

The tuning sets are activated by clicking .


Figure 10.

Batch Runs (Interactive)

You can submit batch runs for a combination of defined model configuration, analysis loadcase, analysis setup and tuning sets.


Figure 11.
The lower section of the Analysis Manager is used to apply the module representation and state selections to the modules in the assembly, realize connections to states defined into corresponding FE entities, render the defined loadcase into solver cards and create FE entities for the selected tuning set. Once an analysis has been applied for the selected analysis type, the Job options section is enabled. If the Create job option is selected, you can select a Job folder and click Create Job, which opens the Job Submission dialog, allowing you to select a number of solver related options. You can select the server, local or HWUL for solving the runs. Clicking Submit Job creates the analysis job and submits it to the target solver for analysis.


Figure 12.

Subsequently, the job will be accessible through the Job Manager. If the Export deck option is selected, click Export to save a solver deck for manual submission to the targeted solver for analysis. All analysis information is saved in the assembly .xml file and retrieved when the file is loaded once again.

Analysis Definitions Import/Export with Template CSV Files

This option allows you to export and import analysis definitions in template .csv files. This will allow you to quickly create analysis definitions by importing the template .csv files, compare and modify analysis definition.

Analysis Definitions Review

This option allows you to compare different analysis.
