Object names in Nonlinear Structural Analysis and Thermal Analysis must adhere to the following rules:

• The name can have up to 50 characters.

• The name can include spaces and most punctuation marks and special characters.

• The name must not begin with a number.

• The name must not begin or end with an underscore or a space.

• The name must not contain a period or double quotes.

• The name must not contain a backslash.

• The name must be unique within the defined scope.

  • Loads, boundary conditions, fields (all propagating objects), constraints, and connection properties

  • Steps

  • Amplitudes, model properties, and connection behaviors

Additional restrictions apply to analysis case names because they are used as file names.

• When you name an analysis case, you cannot use the following characters:

  <space>$&*~!()[]{}|:;'`”,.?/\>< 
  

In general, when you are specifying a name that will be used external to Nonlinear Structural Analysis or Thermal Analysis, such as a file name, you should avoid any character that may have a reserved meaning on your platform.

Nonlinear Structural Analysis and Thermal Analysis retain the case of any text you enter. For example, if you name a load PRESSURE in the Pressure dialog box, the load will appear as PRESSURE in the specification tree. However, within the solver all text is case insensitive; you cannot use case to distinguish between objects such as loads and boundary conditions. If you create a load called PRESSURE, you cannot create a second load called Pressure.
