ECHO - Output Control
ECHOON - Output Control
ECHOOFF - Output Control
The ECHO command can be used in the I/O Options section causing OptiStruct to write the interpreted forms of subcase information and bulk data entries to the .out file.
The ECHOON command can be used in the I/O Options, Subcase Information, or Bulk Data sections causing OptiStruct to write (verbatim) any subsequent I/O options, subcase information, or bulk data entries to the .out file until an ECHOOFF command is encountered.
The ECHOOFF command can be used in the I/O Options, Subcase Information, or Bulk Data sections causing OptiStruct to not write any subsequent I/O options, subcase information, or bulk data entries to the .out file until and ECHOON command is encountered.

option1 |
<SHORT, PUNCH, |
SHORT: |
Only entries having less than 20 instances are echoed to the .out file. |
| Default = blank |
PUNCH: |
Writes interpreted echo of all bulk data entries to the .echo file. |
|
|
{cardname}: |
Only bulk data entries with the given {cardname} are echoed to the .out file. |
||
|
EXCEPT {cardname}: |
Only bulk data entries with the given {cardname} are not echoed. |

|
|
|
blank: |
Writes interpreted forms of all subcase information and bulk data entries to the .out file. |

Option2 |
<PARSED> |
PARSED: |
Bulk data entries are converted to free format (comma separated) before echoing. |
| Default = blank |
blank: |
Bulk data entries are echoed verbatim. |

When an ECHO command is not present, no input information is echoed.
The interpreted echo always includes SUBCASE cards (solution related), but not output control cards.
The cards are organized within groups, e.g. optimization cards will appear after model definition cards, and most cards will be sorted by their numerical IDs.
The interpreted echo may contain some cards that are automatically generated or converted during reading (e.g. a CQUADR card will show as CQUAD4, or a CMASS1 card will show as a CMASS3 when only scalar points are referenced). Unreferenced cards may not show in the printout. PARAM cards will not be shown.
The interpreted echo is always printed using a fixed field format (8 character fields) except DMIG cards, which are printed using free format (comma separated fields) with 10 decimal digits accuracy. Note that the use of IDs larger than 99,999,999 is allowed in OptiStruct, but ECHO will not be usable in these cases as such IDs cannot be printed in fixed format.
DMIG cards are usually very large and are not shown in the interpreted echo. Adding the card OSDIAG,167,1 anywhere in the control section will force full printout of DMIG cards if the interpreted echo is requested.
{cardname} contains the list of all cards which are to be included in the interpreted echo (or excluded, if EXCEPT keyword is present). This list may contain ELEM or PROP keywords, which is equivalent to listing all valid element or property names respectively.
Multiple ECHO cards are allowed; all parameters of these cards are accumulated in the order in which they are input. EXCEPT may appear anywhere (e.g. before or after {cardname} list) and may be repeated on multiple cards.
ECHOON / ECHOOFF cards may appear in any section of the input deck.
All comment cards, empty cards, and characters after the $ character on any card will not be printed in any ECHO format.
The .echo file generated when 'ECHO = PUNCH' is defined represents a copy of the input deck in a form suitable to use for another solution which, when used with the same Subcase Information and I/O Options entries, should generate identical results (round off error may be noticeable if the original input deck uses large field format).
