EqTypeSpecifies the PDE system to solve, based on the choices in the table above.
TemperatureSpecifies 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.
BCTypeSpecifies the type of boundary condition to apply when the
IterativeElasticSystemis being used.
Normal: The boundary conditions are split into
NumStepssteps, 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.
