Create a default IMAT_FEM object.
fem=imat_fem
fem=imat_fem([])
fem=imat_fem(cs,node,elem,tl)
fem=imat_fem(cs,node)
The IMAT_FEM class contains FEM coordinate system, node, element, and traceline information. It provides a number of methods for working with the data.
IMAT_FEM with no arguments will create an empty IMAT_FEM object with the global cartesian coordinate system defined.
IMAT_FEM([]) will create an empty IMAT_FEM object with no coordinate systems.
IMAT_FEM(S), where S is a structure containing fields with the same name as the properties of IMAT_FEM will convert the structure into an IMAT_FEM object.
IMAT_FEM([CS][,NODE][,ELEM][,TL]) where the inputs are IMAT_CS, IMAT_NODE, IMAT_ELEM, and IMAT_TL objects, respectively, will return an IMAT_FEM object containing these inputs.
The IMAT_FEM object contains several properties that define it:
| .cs | IMAT_CS containing coordinate system information |
| .node |
IMAT_NODE containing node information |
| .elem |
IMAT_ELEM containing element information |
| .tl |
IMAT_TL containing traceline information |
