Material Models

• Quasi-static solid deformation
• Linear-elastic material

One-dimension

• Hooke's law

Two-dimensions

• Plane strain
• Plane stress

• Prescribed displacements on sets of degrees of freedom (DOF)
• Prescribed tractions on sets of degrees of freedom (DOF)
• Prescribed tractions on node sets

One-dimension

• L2: Linear rod element with two nodes

Two-dimensions

• Q4: Bilinear quadrilateral element with four nodes
• Q9: Quadratic quadrilateral element with 9 nodes
• T3: Linear triangular element with three nodes

Only meshes of a single element type are currently supported.

Built-in Mesh Generator

The program contains a built-in mesh generator for structured meshes. The mesh generator currently supports the creation of meshes using the following element types:

• L2
• Q4
• B8

GMSH Import

The program also supports the import of a mesh from GMSH. The imported mesh may consist of the following element types:

• L2
• T3
• Q4
• Q9

Stress/Strain recovery

• Element center
• Nodal averaging
• L2 projection

Visualization

• Results are exported to the VTK file which can be read in Paraview.
