READ<br />

Extracts real symmetric system eigenvaules<br />

Parameters:<br />

FORMAT Input-Character-no default. If FORMAT≠ ’MODES’, READ will solve a<br />

buckling problem, i.e., ( K + [ ] )<br />

using EIGB Bulk Data. But it is the<br />

[ ] λ K d<br />

<strong>DMAP</strong> writer’s responsibility to multiply K d by -1 before entering the<br />

READ module.<br />

NEIGV Output-integer-no default. NEIGV is the number of eigenvectors<br />

found.<br />

0 No eigenvectors found<br />

>0 NEIGV eigenvectors found<br />

0, then METHOD command is ignored and the EIGR, EIGB, or<br />

EIGRL is selected by this parameter value. All subsequent parameter<br />

values (METH, F1, etc.) are ignored.<br />

If SID=-1, then both the METHOD command and all EIGR, EIGB, or<br />

EIGRL entries are ignored and the subsequent parameter values<br />

(METH, F1, etc.) will be used to control the eigenvalue extraction.<br />

If SID=-2, then take action similar to SID=0 except fields on the Case<br />

Control selection of EIGR/EIGRL may be overridden by parameters F1<br />

through NORM described below.<br />

METH Input-character-default='LAN'. If SID
