名称 描述 tria3 CTRIA3— Triangular Element Connection Defines a triangu lar plate element (TRIA3) of the stru ctu ral model. This element u ses a 6 degree-of-freedom per node formu lation 定义机构模型的三角形板单元。这一单元用每节点 6 自由度表达 CTRIAR—Triangular Element Connection CTRIAR entry is equivalent to CTRIA3. Unlike other Nastran codes, a 6 degree-of-freedom per node formulation is used for all shell elements. CTRIAR 条目相当于 CTRIA3。不像 nastran 有限元软件代码，6自由度的每节点用于所有壳单元。 BMFACE—Barrier Mesh Face Defines quad or tria faces that are in turn used to define a barrier to limit the total deformation for free-shape design regions. 定义四或三表面反过来用于定义限制自由形状设计区域的总变形。 PLOTEL3—Dummy Plot Element Definition Defines a three-noded, two-dimensional dummy element for use in plotting 定义了一个三节点，用于绘制二维虚拟单元 CAABSF—Frequency-dependant Fluid Acoustic Absorber Element Defines the frequency-dependant fluid acoustic absorber element in coupled fluid-structural analysis 定义了依赖于频率的流体吸声器元件耦合流体结构分析 DTRIA3— 无 Qu ad4 CQUAD4—Quadrilateral Element Connection Defines a quadrilateral plate element (QUAD4) of the structural model. This element uses a 6 degree-of-freedom per node formulation 定义了一个四边形板单元的模型结构。这一单元用每节点 6 自由度表达 CQUADR—Quadrilateral Element Connection CQUADR entry is equivalent to CQUAD4. Unlike other Nastran codes, a 6 degree-of-freedom per node formulation is used for all shell elements CQUADR 相当于 CQUAD4，不像其他有限元软件，6 自由度的每节点用于所有壳单元。 BMFACE 同上 CSHEAR—Shear Panel Element Connection Defines a shear panel element 定义剪切面板单元 PLOTEL4—Dummy Plot Element Definition Defines a four-noded, two-dimensional dummy element for...
