All element node numbers (except special-purpose nodes, discussed later) will increase by the same value. The increment in node numbers of corresponding nodes from element to element in the row.

The number of elements to be defined in the first row generated, including the master element. The master element must exist at the time that the generation is specified, although it can be an element that has just been defined in this same element generation. To generate a row of elements, you must specify the following information: This row can then be repeated to form a layer, which can also be repeated to form a block. The newly created elements are always the same element type as that of the master element.Ībaqus first generates a row of elements by copying the node pattern of a given element with prescribed increments in the node and element numbers.

You can generate elements incrementally from existing elements. *END ASSEMBLYThis element set definition is equivalent to the previous example, where the elements are listed individually.Ĭreating elements from existing elements by generating them incrementally However, since in this example the same elements are assigned to both the part- and assembly-level element sets set1, the assembly-level set could alternatively be defined by *ASSEMBLY, NAME=Assembly-1 An assembly-level element set called set1 could be created with entirely different elements than those that belong to the part set part- and assembly-level element sets are independent. Therefore, the elements are assigned to two separate element sets: one at the part instance level and one at the assembly level. *END ASSEMBLYAssembly-level element set set1 contains all the elements from element sets set1 belonging to part instances PartA-1 and PartA-2. *END PARTAn element set with the same name is defined at the assembly level as follows: *ASSEMBLY, NAME=Assembly-1 The following input defines an element set, set1, that belongs to part PartA and will be inherited by every instance of PartA: *PART, NAME=PartA odb) files will use the normal gasket element connectivity. If both element faces are part of contact surfaces, the connectivity of a 20-node brick element can be used, and Abaqus/Standard will generate the node numbers and coordinates of the midface nodes automatically.Ībaqus/Standard will transform the solid element connectivity to the normal gasket element connectivity immediately upon reading the data. The 18-node gasket element is an exception. The solid element must have the same number of nodes on each face as the corresponding gasket element any nodes between the faces will be ignored. If the equivalent solid element is oriented differently, specify the face number on the solid element that corresponds to the first face of the gasket element. By default, it is assumed that the first (S1) face of the solid element coincides with the first (SNEG) face of the gasket element. For such cases you can specify that solid element connectivity is used to define the gasket element.

The node numbering scheme for gasket elements does not correspond to the node numbering scheme for continuum elements, which can be inconvenient if the mesh generator used does not support gasket elements directly or in thermal-stress analysis where continuum elements are used to model the heat conduction in the gasket. Using solid element connectivity to define gasket elements Abaqus/Standard will then generate the node numbers and coordinates of the midface nodes automatically. To invoke this feature, you enter a blank instead of the actual node numbers in either of the above input methods.

For the 18-node gasket element you give the first eight nodes followed by the midsurface node i.e., node 17 in the full element nodal connectivity.Ībaqus/Standard can generate the midface nodes of the 18-node gasket elements automatically if both element faces are part of contact surfaces. In the second method you specify only the nodes on the bottom surface of the gasket element and a positive offset number that will be used to define the corresponding nodes for the top surface. In the first method you define individual elements by specifying the element number and the nodes that define the element. (See “Gasket elements: overview, ” Section 32.6.1 “Including gasket elements in a model, ” Section 32.6.3 and “Defining the gasket element's initial geometry, ” Section 32.6.4, for more information on gasket elements they are available only in Abaqus/Standard.) There are several methods for defining gasket elements.
