ASPECT Newsletter #116

Hello everyone!

This is ASPECT newsletter #116.
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:

#3924: remove some unnecessary includes (implemented by tjhei; reviewed by bangerth)
#3923: implement timestep repeating with mesh deformation (implemented by tjhei)
#3922: [WIP] Add isostress and Voigt-Reuss-Hill averaging to CompositeViscoPlastic (implemented by bobmyhill)
#3920: Fix deprecation warnings (implemented by gassmoeller; reviewed by bangerth)
#3919: Use deal.II particle copy (implemented by gassmoeller; reviewed by bangerth)
#3918: added viscous damper to elasticity to make firmoviscous material (implemented by bobmyhill)
#3917: Fix changelog (implemented by gassmoeller; reviewed by naliboff)
#3916: Change test viscosity from 0 to 1 (implemented by anne-glerum)
#3915: Added functor to do geometric averaging of viscosities (WIP). (implemented by alarshi)
#3914: Update current stress taking strain weakening into account (implemented by anne-glerum)
#3912: Discuss choices of approximate models better in the manual. (implemented by bangerth; reviewed by bobmyhill)
#3911: Simpler material model: remove reference_T (implemented by tjhei; reviewed by gassmoeller)
#3910: update parameters (implemented by tjhei; reviewed by gassmoeller)
#3909: www: create a redirect to manual.pdf (implemented by tjhei; reviewed by gassmoeller)
#3908: ViscoPlastic rheology migrated into separate rheology module (implemented by bobmyhill; reviewed by naliboff)
#3905: Fix script (implemented by tjhei; reviewed by gassmoeller)
#3896: Add option to use the adiabatic temperature in the multicomponent incompressible density equation (implemented by naliboff; reviewed by naliboff)
#3893: Modified the plugin for depths more than the input viscosity file. (implemented by alarshi; reviewed by gassmoeller)
#3805: create and use is_defect_correction helper function. (implemented by MFraters; reviewed by bangerth)

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

#3921 Is checkpointing a significant time sink? (opened)
#3913 Material average fails when viscosity is not required (opened)
#3904 Update scripts in /doc (closed)
