Tolerances | • Division - prevents divide by zero errors. • Numerical - determines if two real values are equal. • Writing determines if a value is approximately zero when generating a Bulk Data entry field. |
Bulk Data Format | • Sorted Bulk Data - Sorts Bulk Data entries alphabetically. • "Card Format - Determines whether real numbers are written to a standard (8 character) NASTRAN field or to a double (16 character) NASTRAN field. If Either is set, the precision necessary will determine whether an 8 or 16 character field is used. The following preference can be included in the settings.pcl file to set the default: pref_env_set_string("NastranCardFormat", value), where value is either "Small," "Large," or "Either." See The settings.pcl File (p. 63) in the Patran Installation and Operations Guide for more details. • Write Stored Precision - When ON it writes all data as double precision if the data double precision information. • Precision Control Options - Specifies where to round off a grid point coordinate, material, property, or other entity value before its written out to the bdf file. For example if this value is specified as 2 the number 1.3398 will be written out as 1.34. This option has been implemented for entities: Grids, Coordinate Frames, MPCs, LBCs, Materials and Properties. |
Node Coordinates | Defines which coordinate frame is used when generating the grid coordinates. |
Coordinate Frame Coordinates | Defines which coordinate frame is used when generating the grid coordinates. This can be set to reference frame, analysis frame, or global. This should not affect the analysis. It only changes the method used in the grid creation. This determines which coordinate frame is referenced in the CP field of the GRID entry. |
MD Nastran Version | Specifies the version of MD Nastran. The version specified here is used for two purposes: to create the full name of the ALTER file to be used, and to determine which Solution Sequence to use. Use only whole numbers and letters; for example, 66a, 67 and 68; 67.5 is the same as 67. This version number can be overridden by setting the environment variable “NASTRAN_VERSION”. |
Number of Tasks | Represents the number of processors to be used to run an analysis. It is assumed that the environment is configured for distributed parallel processing. |
Write Properties on Element Entries | Specifies that properties will be written to the element entries for all elements where it is allowed in MD Nastran. |
Write Continuation Markers | This option is OFF by default. This option can be turned ON to write continuation markers for Bulk Data entries. |
Write Global Ply IDs | When ON, attempts to keep the Global Ply IDs consistent between MD Nastran and Patran. |
Convert CBARs to CBEAMs | Converts all CBARs to CBEAMS |
Write PARTSuperelement | This is ON by default and if ON and superelements are selected (see Select Superelements, 344 then BEGIN BULK SUPER = id sections are written in to the input file for each selected superelement. If OFF and superelements are selected, then SESET entries are written instead to define the superelements. |
Geometry Check | Checks the element shapes to make sure they are valid. You can set different warning levels from None to Fatal depending on how crucial the element shapes are to your model. |
Use Iterative Solver | Activates the iterative solver for analysis. The analysis manger does not support this option and must be disabled when using this option. |
Ext. Superelement Spec... | Subform used for defining superelement specifications. |
Numbering Options... | Subform used to indicate offsets for all IDS to be automatically assigned during translation. |
Bulk Data Include File... | Prompts you for the filename of the include file. |
