Total num of nodes
Specifies the total number of nodes.
Total num of elements
Specifies the total number of elements.
Number of Data at each node
Specifies the number of data at each node. If node data isn't exist, Set to 0.
Number of Data at each element
Specifies the number of data at each element. If node data isn't exist, Set to 0.
Number of data for each model
this value must be set to 0.
Node number
the nodes are numbered starting from 1 to define coordinate values.
X coordinate Y coordinate Z coordinate
the coordinates of each direction are specified separated using the
space character. Even for planar elements such as triangles and quadrilaterals,
the Z coordinate(0) has to be specified.
Element number
An integer starting with 1 used to distinguish each element.
Material number
this value must be set to 0.
Types of elements
The elements described earlier are specified using keywords. The keywords
corresponding to each element is shown in the Table.
Types of Elements | keywords |
point | pt |
line | line |
triangle | tri |
quadrilateral | quad |
tetrahedron | tet |
pyramid | pyr |
prism | prism |
hexahedron | hex |
Keyword for each element
Connectivity of nodes that make up the element
the connectivity of nodes is specified using the node numbers described
earlier. Space is inserted between two numbers. The order in which the nodes
of each element are connected depends on the numbers assigned to them
in the Fig.
Number of data components for each node
The number of data components per node is specified. The value is the same as
that specified in the first line (Number of data for each node).
Number of structures
A number of 1s equal to the number of data components at each node are
specified. The 1s are separated by spaces.
Labels for the data components at each node
Labels are assigned to data components at each node. A comma , is inserted
after each label to separate it from the next. If there are more than two data
components and multiple labels are to be specified, then the labels can be
specified on different lines.
Labels for the data components at each element
Labels are assigned to data components at each element. A comma , is inserted
after each label to separate it from the next. If there are more than two data
components and multiple labels are to be specified, then the labels can be
specified on different lines.
Note: Even if units are not specified, a comma is to be inserted after each label.
Units (optional)
A unit is specified for the data components of each node. However, this
specification is optional.
Node number
A number assigned initially to each node to enable definition of coordinate
values. Here, these numbers are used to define data.
Node data
Node data is specified to the right of each node number. If there are multiple
data, they are separated by spaces.
Element number
these numbers are used to define Element data.
Element data
Element data is specified to the right of each element number. If there are multiple
data, they are separated by spaces.
comments
Lines begining with # are comments and are ignored. However, no comments can be entered within the data description.number of step
Defines the number of steps in the file. If this line isn't exist, the format is recognized as the simple step format.cycle type
cycle type can take three values that are data, geom and data_geom. For each of these types, the data is ordered as given below.data
Geometry data is defined only in the first step. Node/Element data is defined in every step.geom
Geometry data is defined in every step while Node/Element data is defiled only in the first step.data_geom
Both geometory and node data are defined in every step.step number
Specifies the step number at the begining of every step. For example, you must specify the first step as step1, the second step as step2 and so on.comment(option)
Comments(optional) Comments on every step can be inserted after the step number.Total num of nodes
