ASPECT Newsletter #215

Hello everyone!

This is ASPECT newsletter #215.
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:

#6281: Get better errors when failing to read an input file. (implemented by bangerth; reviewed by tjhei)
#6280: Change pressure scaling factor and Mp_preconditioner for Weighted BFBT. (implemented by quangx)
#6279: Check if normalized fields are smaller then the number of compositional fields. (implemented by MFraters; reviewed by tjhei)
#6278: Fix underflow bug in isosurfaces mesh refinement plugin (implemented by MFraters)
#6275: Fix named additional output postprocessor with entropy material model (implemented by gassmoeller)
#6274: Only ask for required outputs in more places (implemented by jdannberg; reviewed by gassmoeller)
#6273: Also output errno when the rename() call fails. (implemented by bangerth; reviewed by gassmoeller)
#6272: [WIP] Add compressible EOS option to visco plastic material model (implemented by naliboff)
#6271: Only compute additional outputs when needed (implemented by jdannberg; reviewed by gassmoeller)
#6270: Make the rotation terms neater (implemented by YiminJin; reviewed by gassmoeller)
#6269: Fix phases for background material and plasticity in the grain size material model. (implemented by gassmoeller; reviewed by gassmoeller)
#6268: Be more explicit when we omit certain operations. (implemented by bangerth; reviewed by tjhei)
#6267: add get_required_properties function to heating plugins (implemented by jdannberg; reviewed by gassmoeller)

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

#6277 Inconsistency in diffusion creep model (opened)
#6276 Change checkpointing restart/resume setup (opened)
