A finite element mesh can be saved in a generic format defined by SMS, called the 2dm format. In addition, the Generic Model interface in the Mesh module uses this format to save a template definition, in addition to model parameter, material property, and boundary condition assignments for a specific simulation. When a *.2dm file is opened, the current numerical model changes to the Generic Model interface. To save a numerical model definition as a template file, first set up the template and save a *.2dm file before any nodes are created.

Field

Variable

Value

Description

n₁ - n_n (number of nodes in nodestring)

n_x

+ integer

The ID's of the nodes in the nodestring. The last node id is written as a negative number, thus signaling the nodestring's end. Multiple NS cards can be used on consecutive lines for a single nodestring.

Note: The nodestring tail is denoted by a negative sign in front of the tail node ID. A nodestring may consist of more than ten nodes which constitute a file line, consequently a nodestring may extend multiple NS cards. Each sequential line should be read until the negative tail node ID is found, ending the nodestring definition. If no nodestrings are present in the mesh, this card will not be written.

Note: Node IDs for all cards above are limited to six digits (i.e. 999999 maximum).

Model Parameter Definition Cards

The model control parameters, boundary conditions and material options available for a specific model are defined in the generic model parameter definition section of the 2D mesh file. The generic model parameter definition section is begun by specifying the BEGPARAMDEF card and ended with the ENDPARAMDEF card.

Starting with SMS version 11.0, all of the parameter cards follow a similar pattern and the available options for several of the types of parameters were increased. The pattern is similar for Global Parameters, GP, Bondary Conditions BC, and Materials MAT. More information can be found in each individual card.
