Notes

Nodes of elements


3000


3000




Interior nodes


3000


3000


In the GUI, interior nodes are defined as a mesh of elements which are flagged as elements in interior of volume.

Elements (total, all subregions)


800


800


This limit is comparable to a volume mesh of 20000100000 high quality hexahedral finite elements.

Elements in subregion


400


400




6node triangular element


yes


yes


High accuracy in general application, comparable to quality of quadrilateral elements.

8node quadrilateral element


yes


yes


Can be more numerically stable in thinwalled subregions than triangles.

9node quadrilateral element


yes


yes


Can be more numerically stable in thinwalled subregions than triangles.

Complete plain strain infinite elements


yes


no


Typically used in geotechnical engineering. GUI can be customised.

Asymptotic decay infinite elements


yes


no


Typically used in geotechnical engineering. GUI can be customised.

Element aspect ratio (max length/min width)


>50:1


>50:1


Where physically sensible.

Subregions


10


10


Subregions are partitions of the model: Used for different material zones. Sometimes used to shorten extreme subregion aspect ratios below max limit.

Subregion aspect ratio (max length/min width)


60:1 ... 350:1


60:1 ... 350:1


Model dependent.

Finite subregions


yes


yes


"open" finite subregions can be defined using implicit symmetry option.

Infinite subregions


yes


no


Typically for geotechnical engineering.

yes


yes




Transversely isotropic linear elastic material


yes


no


Fully anisotropic linear elasticity is implemented in the solver.

* Solver = stand alone module without graphical user interface, which can be started under Windows command prompt (cmd.exe).
* GUI = graphical user interface. This is the normal mode of use.
