FreeFEM v4.2.1

Warning: this is an automatic release. If you encounter some trouble, please post a message on the forum

Added

• nested fieldsplit example examples/hpddm/natural-convection-2d-PETSc-fieldsplit.edp
• int[int][int] array; is now supported (a size was previously needed, i.e., array(0);)
• check selectivity during make check, depending on available 3rd party librairies
• new CI/CD tools for develop branch
• new gestion of mesh3 - meshS coupling
• square3, buildSurface, ... operators for meshS

Changed

• SLEPc is now directly downloaded by PETSc with --download-slepc
• HPDDM and PETSc API have been simplified, instead of an int[int] and an int[int][int], only a single int[int][int] is now needed
• build macros for HPDDM and PETSc have been simplified to follow the above API change, two parameters have been permuted as well to match the HPDDM and PETSc constructors
• PETSc version 3.11.2 and HPDDM with multilevel GenEO

Removed

• old interfaces that were not maintained anymore (pARMS, PaStiX, hips) and that are available through PETSc
• spurious outputs when destroying some meshes
• old surface msh3 type, replaced by meshS

Fixed

• multiple segmentation faults when using unitialized values (thanks to G. Sadaka)
• nested fieldsplits in the PETSc interface
• memory leaks in SNESSolve (nonlinear PETSc solvers)
• bug fix of Cofactor function
• various bug fixes on surface mesh
