Basic Model Builder

This command is used to construct the BasicBuilder object.

model BasicBuilder -ndm $ndm <-ndf $ndf>

$ndm

dimension of problem (1,2 or 3)

$ndf

number of degrees of freedom at node (optional)

(default value depends on value of ndm:

ndm=1 -> ndf=1

ndm=2 -> ndf=3

ndm=3 -> ndf=6)

These additional commands allow for the construction of Nodes, Masses, Materials (nDMaterial Command, uniaxialMaterial Command), Sections, Elements, LoadPatterns, TimeSeries, Transformations, Blocks and Constraints. These additional commands are described in the subsequent chapters.

EXAMPLE:

model basic -ndm 3 -ndf 6; # 3 spacial dimensions, 6 DOF's per node

For an example of this command, refer to the Model Building Example

NOTE:

The model command can be used many times in the model to define different DOF regions (ndf=3 for frame elements, ndf=2 for solid elements)
