RESULTS CALCULATE SCAN LOADCASE Scan_name

              

This command performs a scan of the chosen results attribute(s) in the currently selected loadcases to find extreme values. At least two loadcases should be selected before the command is issued.

Scan_name = The name to be given to a new scan loadcase (to contain the output of the scan) or the name of an existing scan loadcase (See notes 1 and 2).

Notes:

1.

Defining a new scan loadcase
If the scan loadcase does not exist the user will first be prompted for the criterion for the scan. The choice is from the following keywords:

MAX = Scan for maximum values

MIN = Scan for minimum values

ABSMAX = Scan for absolute maximum values

ABSMIN = Scan for absolute minimum values

The user will next be prompted for a description of the scan loadcase, and finally the name of the results attribute(s) to be scanned.

2.

Using an existing scan loadcase
If the scan loadcase already exists, then the existing definition of the scan will be referenced and the user will only be prompted for the name of the results attribute(s) to be scanned.

3.

Selecting the results attribute(s) to be scanned
During the scan procedure, the user will be prompted to specify the attribute(s) to be scanned. The list of attributes available to be scanned are those attributes that exist in the first source loadcase specified in the definition of the scan. In addition, the user may use the keyword CURRENT to request that the current results attribute be scanned, or the keyword ALL to request that all the available attributes in the attribute list be scanned.

If an attribute that already exists in the scan loadcase is specified then the scan request will be ignored. An error message will be displayed, the scan command will be aborted and existing attribute data in the scan loadcase will not be overwritten.

An attribute cannot be scanned unless it exists in all of the source loadcases specified in the definition of the scan, or if it contains more than ten components, or if it contains enumerative or complex components. In these cases an error message will be displayed and the scan command will be aborted.

4.

Status on command completion
On successful completion of the scan loadcase command, the scan loadcase will become the current loadcase. The results attribute and component that will become current will depend on which attribute selection was made:

i.

If the attribute was selected from the attribute list then the first component of that attribute will be made current.

ii.

If the CURRENT attribute was selected then the current component of that attribute will remain current.

iii.

If ALL attributes were selected then no attribute will be made current.

5.

Use of scan loadcases
Results stored in scan loadcases may be accessed and presented in the normal way, with the exception of RESULTS CALCULATE commands which are blocked.

6.

Use of scan loadcases with assemblies
It is not currently possible to define and perform a loadcase scan on an assembly model. However, any scan loadcases existing in the models used to create the assembly will exist in the assembly model, and the user should ensure that the definition of the loadcase scan is consistent for each model in the assembly.

Examples:

1.

RESULTS CALCULATE SCAN LOADCASE SCAN1

The following is an example prompt sequence if `SCAN1' is a new scan loadcase:

 CRITERION => MAX
 20 Character Ref => Max values in L1-L4
 ATTRIBUTE => ALL

2.

RESULTS CALCULATE SCAN LOADCASE SCAN2

The following is an example prompt sequence if `SCAN2' is an existing scan loadcase:

 ATTRIBUTE => NODAL STRESS
