geom4 Module

defines readers for BDF objects in the OP2 GEOM4/GEOM4S table

class pyNastran.op2.tables.geom.geom4.GEOM4

Bases: pyNastran.op2.tables.geom.geom_common.GeomCommon

defines methods for reading op2 constraints

pyNastran.op2.tables.geom.geom4.fill_rbe3_wt_comp_gijs(i, j, idata, fdata)

helper for read_rbe3s_from_idata_fdata

pyNastran.op2.tables.geom.geom4.get_minus_2_index(idata)

helper for get_minus_2_index

pyNastran.op2.tables.geom.geom4.read_rbe3s_from_idata_fdata(self, idata, fdata)

1 EID I Element identification number 2 REFG I Reference grid point identification number 3 REFC I Component numbers at the reference grid point

4 WT1 RS Weighting factor for components of motion at G 5 C I Component numbers 6 G I Grid point identification number Word 6 repeats until -1 occurs

Words 4 through 6 repeat until -2 occurs

7 GM I Grid point identification number for dependent degrees-of-freedom 8 CM I Component numbers of dependent degrees-of-freedom

Words 7 through 8 repeat until -3 occurs
