Using custom durability parameters

In Specialist Durability, you can create custom simulation object, analysis template, solver parameter, and solver profile definitions and store them in custom parameter libraries. You can use these custom parameter definitions when you define a specialist durability analysis template or solver profile. The parameter libraries are stored in XML file format.

Site and user parameter libraries

You can store custom parameter definitions in two custom libraries: site parameter library for all users, and user parameter library to which only certain users have access. Use customer defaults for the parameter library to:

• Define the default location of the custom parameter libraries.

• Define user access to the custom parameter libraries.

Local parameters

You can create a custom parameter definition or load one from the parameter library to use in the local Simulation file. When you use a parameter definition in your Simulation file, the parameter is saved as a local parameter, and you cannot edit it. If you modify a parameter definition in the parameter library file, you can manually update the local parameter with the new properties. For more information on how to manage the parameter definitions, refer to Creating durability analysis templates and simulation objects and Creating durability solver parameters and solver profiles.

Directory structure

You store the custom parameter definitions and library files in the corresponding site or user directory in a sub directory called dur. You store the library files directly under the dur folder, and the parameter definition files for the simulation objects and solver parameters under the dursimobj and dursolverparam subfolders, respectively.

Durability simulation object

Parameter definition:

• dursimobj directory

• dursimobj\dursimobj_def.xml file

Library file: dursimobj_Library.xml

Durability analysis template

Library file: duranalysistype_Library.xml

Durability solver parameter

Parameter definition:

• dursolverparam directory

• dursolverparam\dursolverparam_def.xml file

Library file: dursolverparam_Library.xml

Durability solve profile

Library file: dursolveprofile_Library.xml

Use the same names for the parameter definition files, library files, dur folder, and the subfolders as shown above. Do not customize these names. The XML files placed outside of the dur folder in the user or site directory should not have the same name as the files above.

You can list the contents of the custom parameter library files in the Parameter group in the parameters and parameter libraries dialog boxes. For example, you can list the custom parameter definitions defined in the dursimobj_Library.xml file in the Durability Simulation Objects and Durability Simulation Object Libraries dialog boxes. The content of the dursimobj_def.xml and dursolverparam_def.xml parameter definition files appear in the Type list in the New Parameter group in the Durability Simulation Objects and Solver Parameters dialog boxes, respectively.

The following is an example of the directory structure for parameter definitions and library files:

custom_libraries
site
dur
dursimobj
dursimobj_def.xml
dursolverparam
dursolverparam_def.xml
duranalysistype_Library.xml
dursimobj_Library.xml
dursolverparam_Library.xml
dursolverprofile_Library.xml
user
dur
dursimobj
dursimobj_def.xml
duranalysistype_Library.xml
dursimobj_Library.xml

Parameter definition and parameter library XMl files

You create custom parameter definition and parameter library files in a correctly structured XML file. Copy the Simcenter 3D default parameter definition and library files to the appropriate directory and manually edit the XML files. The Simcenter 3D default parameter definition and library files are stored in the [software_installation_path]\simulation\parameters\dur directory. The following is an example of a durability simulation object definition file:

<Parameters versionNumber="1">    <DurSimObj name="New damage sum limit"               neutralName="newdamagesumlimit"               type="100025"               contextHelp="User Manual"               versionNumber="1">        &baseProperties;        &libraryType;        &parameterType;        <Group label="Categorization"               expanded="false">            &category;        </Group>        <!-- Properties Tab -->        <Group label="Properties">            &newdamageSumLimit;        </Group>    </DurSimObj></Parameters>

You must enter a unique neutralName and type for each parameter. In case of conflicting names, a Simcenter 3D default parameter has priority over a custom one. The software does not load the custom parameter that has the same neutralName or type as a default parameter. Between the user and site parameters, the priority is the user one.

Where do I find it?

Application	Pre/Post
Command Finder	Customer Default
Location in dialog box	Gateway→Parameter Library→Location tab→Site and User Parameter Library Format = Directory of Parameter Library Files(Site Parameter Library): Windows (under Directory Name) = The parent directory of all site libraries(User Parameter Library): Windows (under Directory Name) = The parent directory of all user libraries
