(character or blank) See Remark 8. * Remark 8: OFFT is a character string code that describes how the offset and orientation vector components are to be interpreted. By default, (string input is GGG or blank), the offset vectors are measured in the displacement coordinate systems at grid points A and B and the orientation vector is measured in the displacement coordinate system of grid point A.At user option, the offset vectors can be measured in an offset coordinate system relative to grid points A and B, and the orientation vector can be measured in the basic system as indicated in the following table: String Orientation Vector End A Offset End B Offset GGG Global Global Global BGG Basic Global Global GGO Global Global Basic BGO Basic Global Basic GOG Global Offset Global BOG Basic Offset Global GOO Global Offset Basic BOO Basic Offset Basic

property PA: int

Pin flags for bar ends A and B, respectively. Used to remove connections between the grid point and selected degrees-offreedom of the bar.The degrees-of-freedom are defined in the element’s coordinate system (see Figure 8-8). The bar must have stiffness associated with the PA and PB degrees-of-freedom to be released by the pin flags. For example, if PA = 4 is specified, the PBAR entry must have a value for J, the torsional stiffness. (Up to 5 of the unique Integers 1 through 6 anywhere in the field with no embedded blanks; Integer > 0.) Pin flags combined with offsets are not allowed for SOL 600.

See Remark 7. and 8. (Real; Default = 0.0) * Remark 7: Offset vectors are treated like rigid elements and are therefore subject to the same limitations. • Offset vectors are not affected by thermal loads. • The specification of offset vectors is not recommended in solution sequences that compute differential stiffness because the offset vector remains parallel to its original orientation. (Differential stiffness is computed in buckling analysis provided in SOLs 103 and 107 through 112 with the STATSUB command; and also in nonlinear analysis provided in SOLs 106, 129, 153, and 159 with PARAM, LGDISP,1.) • BAR elements with offsets will give wrong buckling results. • Masses are not offset for shells. • The nonlinear solution in SOL 106 uses differential stiffness due for the iterations to reduce equilibrium errors.An error in the differential stiffness due to offsets may cause the iterations to converge slowly or to diverge. If the solution converges the answer is correct, even though there may be an error in the differential stiffness.However, the special capabilities in SOL 106 to get vibration and buckling modes will produce wrong answers if the differential stiffness is bad. • The internal “rigid elements” for offset BAR/BEAM elements are rotated in the nonlinear force calculations. Thus, if convergence is achieved, BAR/BEAM elements may be used in SOL 106 with LGDISP,1. * Remark 8: OFFT is a character string code that describes how the offset and orientation vector components are to be interpreted.By default (string input is GGG or blank), the offset vectors are measured in the displacement coordinate systems at grid points A and B and the orientation vector is measured in the displacement coordinate system of grid point A. At user option, the offset vectors can be measured in an offset coordinate system relative to grid points A and B, and the orientation vector can be measured in the basic system as indicated in the following table: String Orientation Vector End A Offset End B Offset GGG Global Global Global BGG Basic Global Global GGO Global Global Basic BGO Basic Global Basic GOG Global Offset Global BOG Basic Offset Global GOO Global Offset Basic BOO Basic Offset Basic

GS is projected onto the surface patches A and B.The resulting piercing points GA and GB define the axis of the fastener.GS does not have to lie on the surfaces of the patches.GS must be able to project normals to the two patches. GA can be specified in lieu of GS, in which case GS will be ignored. If neither GS nor GA is specified, then (XS, YS, ZS) in basic must be specified. If both GA and GB are specified, they must lie on or at least have projections onto surface patches A and B respectively. The locations will then be corrected so that they lie on the surface patches A and B within machine precision. The length of the fastener is the final distance between GA and GB. If the length is zero, the normal to patch A is used to define the axis of the fastener. Diagnostic printouts, checkout runs and control of search and projection parameters are requested on the SWLDPRM Bulk Data entry.

(Character) If TYPE = ‘PROP’, the surface patch connectivity between patch A and patch B is defined with two PSHELL(or PCOMP) properties with property ids given by IDA and IDB.See Remark 1. and Figure 8-22. If TYPE = ‘ELEM’, the surface patch connectivity between patch A and patch B is defined with two shell element ids given by IDA and IDB.See Remark 1. and Figure 8-22. * Remark 1: The CardCfast defines a flexible connection between two surface patches. Depending on the location for the piercing points GA and GB, and the size of the diameter D(see PFAST), the number of unique physical grids per patch ranges from a possibility of 3 to 16 grids. (Currently there is a limitation that there can be only a total of 16 unique grids in the upper patch and only a total of 16 unique grids in the lower patch.Thus, for example, a patch can not hook up to four CQUAD8 elements with midside nodes and no nodes in common between each CQUAD8 as that would total to 32 unique grids for the patch.)

Reference temperature for the calculation thermal loads, or a temperature-dependent thermal expansion coefficient.See Remark 7. (Real or blank) * Remark 7: TREF is used in two different ways: • In nonlinear static analysis(e.g., SOL 106), TREF is used only for the calculation of a temperature-dependent thermal expansion coefficient.The reference temperature for the calculation of thermal loads is obtained from the TEMPERATURE(INITIAL) set selection. See Figure 5-91 in Remark 10. in the MAT1 description. • In all solutions except nonlinear static analysis, TREF is used only as the reference temperature for the calculation of thermal loads. TEMPERATURE(INITIAL) may be used for this purpose, but TREF must then be blank.

property MID4: int

Material identification number for membrane-bending coupling. See Remarks 6. and 13. (Integer > 0 or blank, must be blank unless MID1 > 0 and MID2 > 0, may not equal MID1 or MID2.) * Remark 6: The following should be considered when using MID4. The MID4 field should be left blank if the material properties are symmetric with respect to the middle surface of the shell.If the element centerline is offset from the plane of the grid points but the material properties are symmetric, the preferred method for modeling the offset is by use of the ZOFFS field on the connection entry. Although the MID4 field may be used for this purpose, it may produce ill-conditioned stiffness matrices (negative terms on factor diagonal) if done incorrectly. Only one of the options MID4 or ZOFFS should be used; if both methods are specified the effects are cumulative.Since this is probably not what the user intented, unexpected answers will result. Note that the mass properties are not modified to reflect the existence of the offset when the ZOFFS and MID4 methods are used.If the weight or mass properties of an offset plate are to be used in ananalysis, the RBAR method must be used to represent the offset. See “Shell Elements (CTRIA3, CTRIA6, CTRIAR, CQUAD4, CQUAD8, CQUADR)” on page 131 of the MSC.Nastran Reference Guide. The effects of MID4 are not considered in the calculation of differential stiffness.Therefore, it is recommended that MID4 be left blank in buckling analysis. * Remark 13: For the CQUADR and CTRIAR elements, the MID4 field should be left blankbecause their formulation does not include membrane-bending coupling.

Material identification number for bending. (Integer >= -1 or blank)

property MID3: int

Material identification number for transverse shear. (Integer > 0 or blank; unless MID2 > 0, must be blank.)

property MID4: int

Material identification number for membrane-bending coupling. See Remarks 6. and 13. (Integer > 0 or blank, must be blank unless MID1 > 0 and MID2 > 0, may not equal MID1 or MID2.) * Remark 6: The following should be considered when using MID4. The MID4 field should be left blank if the material properties are symmetric with respect to the middle surface of the shell.If the element centerline is offset from the plane of the grid points but the material properties are symmetric, the preferred method for modeling the offset is by use of the ZOFFS field on the connection entry. Although the MID4 field may be used for this purpose, it may produce ill-conditioned stiffness matrices (negative terms on factor diagonal) if done incorrectly. Only one of the options MID4 or ZOFFS should be used; if both methods are specified the effects are cumulative.Since this is probably not what the user intented, unexpected answers will result. Note that the mass properties are not modified to reflect the existence of the offset when the ZOFFS and MID4 methods are used.If the weight or mass properties of an offset plate are to be used in ananalysis, the RBAR method must be used to represent the offset. See “Shell Elements (CTRIA3, CTRIA6, CTRIAR, CQUAD4, CQUAD8, CQUADR)” on page 131 of the MSC.Nastran Reference Guide. The effects of MID4 are not considered in the calculation of differential stiffness.Therefore, it is recommended that MID4 be left blank in buckling analysis. * Remark 13: For the CQUADR and CTRIAR elements, the MID4 field should be left blankbecause their formulation does not include membrane-bending coupling.
