Supported element types for ANSYS pyramid transitions

The types of elements you can connect with pyramid elements depend upon the Analysis Type you selected in the Create Solution dialog box.

Transition type	ANSYS Structural support	ANSYS Thermal support
Linear hexahedral to linear tetrahedral	No	Yes
Linear hexahedral to parabolic tetrahedral	Yes	Yes
Parabolic hexahedral to linear tetrahedral	No	No*
Parabolic hexahedral to parabolic tetrahedral	Yes	Yes

Note:

*Although ANSYS lets you create transitional pyramid elements between a parabolic hexahedral and a linear tetrahedral mesh in a thermal analysis, this transition type is not supported in Pre/Post. However, you can import ANSYS models into Pre/Post that contain this type of transition. While you cannot modify the mesh in Pre/Post, you can still solve the model.

In ANSYS, pyramid elements are simply degenerate forms of certain types of linear and parabolic solid elements. The type of pyramid element the software creates depends upon the types of elements the pyramid connects. For more information on ANSYS elements, see the ANSYS Element Reference manual.

Linear hexahedral to linear tetrahedral transitions

In the ANSYS Thermal environment only, if you connect linear hexahedral (SOLID70) elements to linear tetrahedral (SOLID70) elements, the software creates 5-noded pyramid (SOLID70) elements.

Linear hexahedral to parabolic tetrahedral transitions

• In the ANSYS Structural environment, if you connect linear hexahedral (SOLID45) elements to parabolic tetrahedral (SOLID92 or SOLID187) elements, the software creates 9-noded pyramid (SOLID95 or SOLID186) elements.

• In the ANSYS Thermal environment, if you connect linear hexahedral (SOLID70) elements to parabolic tetrahedral (SOLID87) elements, the software creates 9-noded pyramid (SOLID90) elements.

In both of these cases, the rectangular faces of the resulting pyramid elements do not have any midside nodes.

Parabolic hexahedral to parabolic tetrahedral transitions

• In the ANSYS Structural environment, if you connect parabolic hexahedral (SOLID95 or SOLID186) elements to parabolic tetrahedral (SOLID92 or SOLID187) elements, the software creates 13-noded pyramid (SOLID95 or SOLID186) elements.

• In the ANSYS Thermal environment, if you connect parabolic hexahedral (SOLID90) elements to parabolic tetrahedral (SOLID87) elements, the software creates 13-noded pyramid (SOLID90) elements.
