![]() ![]() This example has 3 nodes, each as UCD object pt. This is an Example ASCII UCD File for a point, this is handy for use with Paraview to render the point object instead of reading point values into a table. After the first attribute line is the list of attribute names along with their type. In the section where attributes are defined, the first line indicates there are 2 attributes, both scalar. The first line header indicates 8 nodes, 1 element, 2 node attributes, 0 element attributes, 0 model attributes. This is an Example ASCII UCD File for a single hexahedral cell with 8 nodes.

Except for the trans argument any of the arguments can be set to derive () which would result in the secondary axis inheriting the settings from the primary axis. This is the format of the AVS ASCII UCD file: Details secaxis () is used to create the specifications for a secondary axis. Optional Node based data descriptions: data vector for nodes and number components that vector is divided into.įor each node data a label on seperate lines label/unit label pair, separated by a comma.įor each node in a separate line, the vector of data values associated with it.Ĭell based data descriptions, if present, then follow in the same order and format as items 4, 5, and 6. Hex (Hexahedron) avs order = 5 6 7 8 1 2 3 4 Quad (Quadrilateral) avs order = lagrit order These are the valid AVS cell types with node order relative to LaGriT ordering conventions as shown at LaGriT Supported Element Types Mid edge nodes are treated like any other node.įor each cell: its cell id, material, cell type, and the list of nodes for the cell connectivity. Node ids must be integers, but any number including non sequential numbers can be used. Numbers defining the overall structure, including the number of nodes, the number of cells, and the length of the vector of data associated with the nodes, cells, and the model.įor each node, its node id and the coordinates of that node in space. The general order of the data is as follows. The input file cannot contain blank lines or lines with leading blanks.Ĭomments, if present, must precede all data in the file. Each component can be either a scalar or a vector. The data is structured as a set of components. The Unstructured Cell Data (UCD) format is described here.Ī UCD data structure consists of an irregular coordinate structure made up of cells of various types.Įach cell has a corresponding number of nodes and connectivity.ĭata can be associated with each node, cell, or the entire “model”. AVS (avs.com) is a data visualization tool with ASCII mesh file formats used by LaGriT as they are easy to read and easy to convert from and to other mesh file formats. ![]()
