[elmts] block

The block [elmts] is used to describe the model that we plan to use according to your particular problem. This block's layout looks as follows:

[elmts]
  [subelmts1]
    type=elment-type2
    dofs=dof1 dof2
    mate=mate-name1
    domain=geometry-domain-name1
  [end]
  [subelmts2]
    type=elment-type2
    dofs=dof1 dof2
    mate=mate-name2
    domain=geometry-domain-name2
  [end]
  ...
[end]

options

The type = option specifies the name of the element type (or the physical model) one wants to use.

dofs= specifies which DoFs we want to use, it should be noted that one of the names in your [dofs] block must be the name we used here.

mate= gives the material name, which should be the block name in your material block, not the material type name!!! This option can be ignored, then your element will not call any material calculation.

domain= determines which domain will be applied to the current element. Users don't usually need this option, then all of your mesh domains will be used by default.

supported element type

The full list of the available element type is:

type=poisson
type=mechanics
type=diffusion
type=cahnhilliard
type=user1[,...,user20]
