NLDPOST, Label
, Key
, FileID
, Prefix
Gets element component information from nonlinear diagnostic
files.
Label
Specifies the type of command operation:
EFLG | — | Element flag for nonlinear diagnostics. |
NRRE | — | Newton-Raphson residuals. |
Key
Specifies the command action:
STAT | — | List information about the diagnostic
files (Jobname.nd For For |
DEL | — | Delete Jobname.nd |
CM | — | Create components for elements that
violate criteria. This value is valid only when |
FileID
Valid only when Label
=
EFLG and Key
= CM, this value specifies
file IDs:
| — | The file ID number. Creates the element components from the diagnostic files corresponding to the specified file ID number in the working directory. |
ALL | — | Creates element components from all
available diagnostic files residing in the working directory. This
value is the default if you do not specify an |
Prefix
Sets the prefix name for components. Specify up to 21 alphanumeric characters.
Based on the nonlinear diagnostic results (created via the NLDIAG,EFLG command), the NLDPOST command creates element components with predefined names.
The following table lists the diagnostic criteria and component
names (with specified prefix and without). Here xxx
corresponds to the file ID (FileID
) of Jobname.ndxxx
or Jobname.nrxxx
.
Elements with: | If prefix is specified: | Without prefix specified: | |||||
---|---|---|---|---|---|---|---|
Too large a plastic strain increment |
|
| |||||
Too large a creep strain increment |
|
| |||||
Too much distortion |
