"shapefuns" block

Custom shape functions are configured in the JSON block "shapefuns".

json { "shapefuns": { "bulk": { "type": "default" }, "line": { "type": "default" }, "surface": { "type": "user1", "functions": 4 } } }

All three subblocks are optional. If a subblock is omitted, AsFem keeps the corresponding shape function as "default".

Available subblocks

• "bulk": bulk-element shape functions.
• "line": line shape functions. This is only valid when the mesh dimension is at least 2.
• "surface": surface shape functions. This is only valid when the mesh dimension is at least 3.

Options inside each shape-function subblock

• "type": required if the subblock is present. Supported values are listed below.
• "functions": required positive integer for user-defined types, and not allowed for "default".

Supported shape-function types

text default user1 user2 user3 user4 user5

The current parser only reads "type" and "functions" here. Extra fields such as "description" from test_input/input-template.json are ignored.
