Description

Extract sub functions from mixed element does not work in parallel. The current code assumes that dofs are stored linearly, and adds an offset (size of a subsystem) to the list of tabulated dofs, which fails in parallel due to renumbering etc.

History

#1 Updated by Niclas Jansson almost 4 years ago

  • Target version changed from 0.8.4-hpc to 0.9.0-hpc

#2 Updated by Aurélien Larcher almost 4 years ago

  • Status changed from New to In Progress
  • Assignee set to Aurélien Larcher

Introduced the FiniteElement class to provide sub spaces offsets and value dimension offsets for mixed elements.
Saving mixed element functions by slicing them with SubFunctions works so far but needs testing.

#3 Updated by Aurélien Larcher over 3 years ago

  • Status changed from In Progress to Closed
  • Estimated time set to 24.00

Needed redesign of the finite element framework.
Closed as the refactoring of finite element space fixes the problem as a by-product.
