Conversion NASTRAN to ABAQUS

[nvhuser]

Hello everyone,

I am trying to perform a simple frequency response analysis using ABAQUS - using a 2-DOF model
Here is the NASTRAN inputdeck:

ID FRF_TWO_DOF
SOL 111
CEND
TITLE = TWO-DOF SYSTEM
SUBTITLE = MODAL FREQUENCY RESPONSE
LABEL =  NASTRAN EXAMPLE
$
SPC = 996
METHOD = 10
DLOAD = 999
FREQ = 888
SDAMPING = 777
$
SET 11 = 1,2
OFREQ = ALL
$
SUBCASE 1
DISPLACEMENT(PHASE,PUNCH) = 11
$
$
BEGIN BULK
$
RLOAD1  999     997                     901
DAREA   997     2       2       20.0
TABLED1 901                                                             +TAB901
+TAB901 0.0     1.0     10.0    1.0     ENDT
$
FREQ1   888     2.      0.10     80

$
TABDMP1 777     CRIT                                                    +TABD7
+TABD7  0.      0.05    100.    0.05    ENDT

$
PARAM,POST,-1
ENDDATA

what I did so far consisted in the conversion of the bulk data from NASTRAN to ABAQUS:

*HEADING

*NODE
       1,                       0.,                       2.,                       0.
       2,                       0.,                       1.,                       0.
       3,                       0.,                       0.,                       0.
*SPRING, ELSET=P1;Default PELAS_N Property
       2,        2
                    100.,
*ELEMENT, TYPE=SPRING2, ELSET=P1;Default PELAS_N Property
      11,        1,        2
*SPRING, ELSET=P2;Default PELAS_N Property
       2,        2
                  10000.,
*ELEMENT, TYPE=SPRING2, ELSET=P2;Default PELAS_N Property
      12,        2,        3
*MASS, ELSET=MASS_00000001
                     0.1,
*ELEMENT, TYPE=MASS, ELSET=MASS_00000001
       1,        1
*MASS, ELSET=MASS_00000002
                     10.,
*ELEMENT, TYPE=MASS, ELSET=MASS_00000002
       2,        2
*NSET, NSET=Anonymous Header SET
       1,        2
*BOUNDARY, TYPE=DISPLACEMENT
       3,        2,         ,                       0.

Does anybody know how to set the dynamical force? how to request the FR-solution until 20 Hz?
Thank you very much
