Hello everyone!
This is ASPECT newsletter #200.
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:
#5982: Use effective strain rate in viscoplastic stress limiter case as well (implemented by anne-glerum; reviewed by bobmyhill)
#5981: Only use reference strain rate during the first nonlinear iteration in viscoplastic material model (implemented by anne-glerum)
#5978: Changed Newton iteration to log-log iteration in CompositeViscoPlastic (implemented by bobmyhill)
#5977: enforce approx peierls in composite viscoplastic (implemented by bobmyhill; reviewed by gassmoeller)
#5976: Add DruckerPragerPower rheology (implemented by bobmyhill; reviewed by gassmoeller)
#5975: Use std::system instead of ::system. (implemented by bangerth; reviewed by bobmyhill)
#5974: Test that manager classes fill both base class member variables consistently. (implemented by bangerth; reviewed by gassmoeller)
#5973: improve docs for drucker prager (implemented by bobmyhill; reviewed by gassmoeller)
#5972: add grain size to composite viscoplastic (implemented by bobmyhill; reviewed by gassmoeller)
#5971: Use pressure consistently for viscous creep in visco-plastic (implemented by gassmoeller; reviewed by bobmyhill)
#5970: Add option to use adiabatic pressure to determine yield stress in visco plastic rheology (implemented by gassmoeller)
#5969: cookbook for a temperature field from an ascii file (implemented by Francyrad)
#5968: Adds new publications (implemented by ljhwang; reviewed by gassmoeller)
#5966: Create a dedicated type to denote something invalid. (implemented by bangerth; reviewed by gassmoeller)
#5965: Use a variable in the base class instead of local ones. (implemented by bangerth; reviewed by gassmoeller)
#5964: Use emplace_back() over push_back(). (implemented by bangerth; reviewed by gassmoeller)
#5963: support different compositions with particles (implemented by tjhei)
#5962: Deprecate Manager functions now available through the base class. (implemented by bangerth; reviewed by gassmoeller)
#5960: allow variable grain size in diffusion creep (implemented by bobmyhill; reviewed by gassmoeller)
#5902: Add fluid velocity postprocessor (implemented by danieldouglas92; reviewed by gassmoeller)
