Examples

  • Stationary non-linear heat transfer

general presentation of interface, single 2D non-linear computation, problem with one gradient but two jacobian blocks

  • Stationary non-linear heat transfer (advanced):

more complex example with heat source and performance comparison with pure FEniCS implementation. Comparison with pseudo-Newton when neglecting the dj_ddT jacobian block

  • Small strain elastoplasticity

2D plane strain and axisymmetric computation, incremental load process with multiple computations,we show how to pass material properties from FEniCS and how to get state variables for post-processing or visualization, automatic registration of "Strain" in plane strain and axisym conditions

  • Large strain 3D elastoplasticity

3D computation with logarithmic deformation setting, we show how to set up the nonlinear solver parameters and show parallel compuations

  • Elastic multiphase model

2D or 3D compuations with a non-standard model using two displacement fields and three generalized gradients, we mention the current limitation on tensor/vector derivatives, e show how to register these non-standard gradients, we highlight the big advantage of the MFront formulation using linear algebra on 4-rank tensors and unicode support

  • Phase-field

coupling between two MFront computations (although the damage problem is linear), we show how to setup the state variables for each problem from the solution of the other

  • Advanced phase-field models

use cohesive-type model and varitional inequality approach for treating irreversibility, also show how to pass spatially varying material properties (inclusions ?)

  • Crystal plasticity

in large strain or with strain gradient model

  • Transient heat equation

show how to write explicitly the variational formulation

  • Monolithic thermoelasticity

  • Monolithic phase-field

  • Porous visco-plasticity

application case of the StandardElastoViscoPlasticity brick extension to porous materials
