Term Overview

Term Syntax

In general, the syntax of a term call is:

<term name>.<i>.<r>( <arg1>, <arg2>, ... ),

where <i> denotes an integral name (i.e. a name of numerical quadrature to use) and <r> marks a region (domain of the integral).

The following notation is used:

The suffix “_0” denotes a quantity related to a previous time step.

Term names are (usually) prefixed according to the following conventions:

Term name prefixes.

prefix

meaning

evaluation modes

meaning

dw

discrete weak

‘weak’

terms having a virtual (test) argument and zero or more unknown arguments, used for FE assembling

d

discrete

‘eval’, ‘el_eval’

terms having all arguments known, the result is the value of the term integral evaluation

ev

evaluate

‘eval’, ‘el_eval’, ‘el_avg’, ‘qp’

terms having all arguments known and supporting all evaluation modes except ‘weak’ (no virtual variables in arguments, no FE assembling)

de

discrete einsum

any (work in progress)

multi-linear terms defined using an enriched einsum notation

Term Table

Below we list all the terms available in automatically generated tables. The first column lists the name, the second column the argument lists and the third column the mathematical definition of each term. The terms are devided into the following tables:

The notation <virtual> corresponds to a test function, <state> to a unknown function and <parameter> to a known function. By <material> we denote material (constitutive) parameters, or, in general, any given function of space and time that parameterizes a term, for example a given traction force vector.
