Element loads are described in Node and Element Loads . Pressures may be input as surface loads on the element faces as shown by the circled numbers on Figure 181.1 . Positive pressures act into the element. Because shell edge pressures are input on a per-unit-length basis, per-unit-area quantities must be multiplied by the shell thickness. For analysis of welded structures, a mix of solid, shell and beam elements are typically used. While solid elements can be used to model bulky parts manufactured by casting and forging processes, shell and beam elements are convenient to represent thin-walled geometries manufactured by sheet metal forming, rolling and drawing operations.
The model looks like this: Shellelement model (NX) It's a shellelement model. At the bottom, the nodes are fixed, and the top nodes have an enforced displacement. The analysis is static nonlinear.

Ansysshellelement bug. We were analyzing an excavator part for strength. We wanted to set up a global model to get all effects from the forces transferring through the hydraulic cylinders. The model was a combination of shellelements and solid bodies. Contacts and joints were set up, and a mesh for checking the connectivity was created. 3. Hot Spot Method. This is similar to what is sometimes done to estimate stresses for weld fatigue. One first creates a path of stress to the singularity. At a certain distance away from the stress singularity (~1mm in the example plot below), it is assumed the stresses are adequately far away and are thus reported. Ansys CFD tools in 2021 have taken another large step forward in terms of model depth and workflow capabilities with the release of Ansys 2021 R1.

Thanks mate! I suggest that you target the default element types used by Ansys WB (for 1D,2D,3D). This would increase the reach of pyansys. If you could throw some light if in the future, with respect to nodal results, you would be giving access to: the averaged, unaveraged on material, unaveraged on real constant, top/bottom solution option for shellelements. All shellelement results are in the element coordinate system. It is important to note this because if a directional stress is desired, users must map the direction of the element x-direction using a material orientation. The default element x-direction is based on the node order of the shell elements. Because the auto mesher “connects the ....
