Supported Finite Elements
pdfPost supports ANSYS elemnt definitions as well as neutral definitions. Following generic definitions (node count and order) user can convert finite elements from any FEA suite.
Generic pdFPost elements
pdfPost_LINE2 element may represent every 2-node line element. If this element is used, component MeshType property needs to be LineSet.
pdfPost_PLANE3 element represent 3-node plane element
pdfPost_PLANE4 element represent 4-node plane element. In case, 4th node is null, 0 or equal to 3rd one, pdfPost_PLANE3 element will be generated.
When using pdfPost ACT Plugin for ANSYS Mechanical, following geometrical representations of finite elements are supported:
Current version of pdfPost (1.5) does not support mid-nodes for SOLID elements. Mid-nodes are ignored during conversion process.
ANSYS Mechanical APDL
Details for each element can be found in ANSYS documentation.
Elements, that share geometrical definition will be converted as well eg.:
- SHELL181 -> SHELL63, PLANE13, …
- SOLID185 -> SOLID96, SOLSH190, …
ANSYS_SHELL181 – 4-Node Structural Shell (including triangular option)
ANSYS_SHELL281 – 8-Node Structural Shell (including triangular option)
ANSYS_SOLID185 – 3-D 8-Node Structural Solid (including prism, tetra and pyramid option)
ANSYS_SOLID186* – 3-D 20-Node Structural Solid (including prism, tetra and pyramid option)
ANSYS_SOLID187* – 3-D 10-Node Tetrahedral Structural Solid
ANSYS_SOLID285 – 3-D 4-Node Tetrahedral Structural Solid
* – current version of pdfPost (1.5) does not support mid-nodes for SOLID elements. Mid-nodes are ignored during conversion process.
