Hello everyone!
This is ASPECT newsletter #138.
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:
#4389: A postprocessor that determines Mobility of the lithosphere following Lourenco et al., 2020 G3 (implemented by elodie-kendall)
#4385: change spherical velocity components to m/yr from m/s if required (implemented by elodie-kendall)
#4384: remove nullspace for cookbooks/S20RTS.prm (implemented by zjiaqi2018; reviewed by gassmoeller)
#4381: remove duplicated code in mesh deformation (implemented by tjhei)
#4379: higher order mesh deformation [WIP] (implemented by tjhei)
#4377: add failing 9.3 test (implemented by tjhei; reviewed by gassmoeller)
#4373: Print solver history on failure if only cheap Stokes solver is used (implemented by gassmoeller; reviewed by tjhei)
#4369: A postprocessor that outputs the second invariant of the deviatoric stress tensor (implemented by anne-glerum; reviewed by gassmoeller)
#4360: Evaluate compositions more efficiently for particles (implemented by gassmoeller; reviewed by tjhei)
#3504: Allow disable EV for compositions at boundaries (implemented by gassmoeller; reviewed by jdannberg)
