ASPECT Newsletter #232

Hello everyone!

This is ASPECT newsletter #232.
It automatically reports recently merged features and discussions about the ASPECT mantle convection code.

Below you find a list of recently proposed or merged features:

#6861: Improve comments in advection assemblers (implemented by gassmoeller)
#6860: Clear up duplicate Newton Stokes assemblers (implemented by YiminJin)
#6858: Unify restoration of particle backup between solver schemes (implemented by gassmoeller; reviewed by anne-glerum)
#6857: Add two papers using ASPECT. (implemented by bangerth; reviewed by gassmoeller)
#6856: Improve documentation of 2 tests (implemented by gassmoeller; reviewed by tjhei)
#6854: Remove a destructor that is not necessary. (implemented by bangerth; reviewed by gassmoeller)
#6853: Fix solver tolerance for Weighted BFBT (implemented by quangx; reviewed by gassmoeller)
#6852: Fix the name of a country. (implemented by bangerth; reviewed by gassmoeller)
#6851: Fix input_t.prm in the nonlinear channel flow benchmark (implemented by YiminJin; reviewed by alarshi)
#6850: MeshDeformation: new initial deformation from constraints (implemented by tjhei; reviewed by gassmoeller)
#6847: add PythonHelper and tests (implemented by tjhei; reviewed by tjhei)
#6841: Fix a place where we write into vectors with ghosts. (implemented by bangerth; reviewed by gassmoeller)
#6829: Fix: Update no flux bcs for mesh deformation (implemented by bobmyhill; reviewed by tjhei)
#6471: Make deviator() and second_invariant() consistent with plane strain assumption in 2D (implemented by YiminJin; reviewed by gassmoeller)

And this is a list of recently opened or closed discussions:

#6859 The nonlinear solver failed to converge in a lower level but converged after mesh refinement (opened)
#6855 Mesh deformation boundary conditions are unclear in some cases (opened)
