[Libmesh-users] Automatic differentiation in LibMesh

Hi All, Can the Function Parser interface in LibMesh: http://libmesh.github.io/doxygen/classlibMesh_1_1ParsedFunction.html be used for computing the Jacobian in PETSc nonlinear solver? Are there any examples showing how to use this? Thanks! Harshad --

[Libmesh-users] Automatic differentiation in LibMesh

Hi LibMesh developers, I saw that MOOSE framework has automatic differentiation capability using Function Parser library. Is it possible to have that in LibMesh? If it's not directly in LibMesh, can I somehow include that code in my program? Thanks, Harshad ---
