Analysis Manager

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.

Figure 2.

The top section of the Analysis Manager is used to define analysis, which is further divided into parts. The first part is for module representation and state selection, the second is for connection state selection, the third part is for loadcase definition and the fourth part if for tuning sets definition for quick modification studies.

Figure 3.

Modules and Connections

Easy and clearer visualization of module and connection states.

Set up of module and connection state for an analysis.

Subsystem analysis: Including/excluding a particular subsystem(s) within an assembly for particular analysis, such as powertrain rigid body modes analysis by grounding the powertrain mounts.

Module Roll-Up/Roll-Down: Capability to set the parent module with CMS-SE representation in H3D format to be used for analysis in lieu of child module representations.

Figure 4.

Multi Sample Analysis

These options allow set up for multi sample analysis by selecting modal parameters of modules and connection properties for randomization and damping.

Connection Parameters

Allows set up of randomization for connection stiffness and damping.

Parameter File

Select the parameters for randomization using an external file generated from the post-processing utility for sensitive parameters.

Number Of runs

User entry for the number of randomization runs for multi sample analysis.

Frequency Scaling

Scaling option for modal frequency randomization.

Figure 5.

Single Sample Analysis

Allows for selecting a particular MSA run and a specific run from it to set up a solver run using parameter values in that selected run with diagnostic requests for further root cause analysis and problem resolution.

Figure 6.

The Auto Selection option allows you to set module representations and states.

Figure 7.

You have the option to select/restore modal parameter modification for reduced models, which is valid only for CMS-SE representation. The checkbox option is only activated if the modal parameters are modified and saved in the Edit module.

Figure 8.

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 Master solver deck.

Figure 9.

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. The different types of analysis available are Regular analysis, Multi sample analysis and Single sample analysis. 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 10.

Figure 11.

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.

In the Analysis Manager, the first step is to create an analysis and define it. Click Edit Analysis to define modules and connections, Solution Type, Extract and Update Analysis, Copy and add Analysis and Delete Analysis.

The following solution types are available:

Frequency Response

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

Frequency & Response selection

Define the analysis type (direct or modal) frequency range of analysis and response types and entities.

Loading point selection

Define the loading points using the template or solver deck. Click Apply when you are done.

Figure 12.

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 13.

Normal modes extraction

Contains an option to specify normal mode extraction parameters for modal frequency response.

Figure 14.

Diagnostic options selection

Request diagnostic options like modal/panel participation, grid participation, auto TPA, ODS and element energy for concerned frequencies using PEAKOUT and OFREQ.

Figure 15.

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.

Figure 16.

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