EqType
Specifies the PDE system to solve, based on the choices in the table above.
Temperature
Specifies the form of the thermal stresses to use. The choices
are:
None
: No stresses (default).
Jacobian
: Sets St = βJI, where β is a parameter defined in the parameters
section, J is the elemental Jacobian determinant and I is the identity matrix.
Metric
: A more complex term, based on the eigenvalues of the metric
tensor. This can only be used for simplex elements (triangles and tetrahedra).
Controlled again by the parameter β.BCType
Specifies the type of boundary condition to apply when the IterativeElasticSystem
is being used.
Normal
: The boundary conditions are split into NumSteps
steps, as defined
by a parameter in the session file (default).
Repeat
: As the geometry is updated, re-evaluate the boundary conditions.
This enables, for example, a cirlce to be rotated continuously.
The following parameters can be specified in the PARAMETERS
section of the session file:
nu
: sets the Poisson ratio ν.E
: sets the Young’s modulus E.beta
: sets the thermal stress coefficient β.NumSteps
: sets the number of steps to use in the case that the iterative elastic
system is enabled. Should be greater than 0.
