Version: v1.4.12

Version 1.4.12

Element assembly for calculation of current and charges from the device into the circuit equation are fixed. These tests are added:

• testing/cap_2d_edge.py
• testing/cap_2d_element.py
• testing/cap_3d_edge.py
• testing/cap_3d_element.py

The edge variant is using standard edge based assembly, and the element variant is using element-based assembly.

Version: v1.4.11

Version 1.4.11

The element_pair_from_edge_model is available to calculate element edge components averaged onto each node of the element edge. This makes it possible to create an edge weighting scheme different from those used in element_from_edge_model.

Fixed issue where command option names where not always shown in the documentation.
