If you are using Ansys 2023 or newer and do not have access to legacy ICEM, you do not need a "SolidSquad" button. You need to use the modern equivalents:
Option A: SpaceClaim (Within Workbench)
Option B: Fluent Meshing Watertight Workflow ansys solidsquad
Option C: PyAnsys / Scripting
For power users, Ansys provides the PyGeometry library. You can write a script that loads a CAD file and runs: If you are using Ansys 2023 or newer
geometry.heal_sliver_faces(tolerance=0.1)
geometry.fill_holes(max_hole_diameter=5.0)
This replicates the batch-processing nature of the original SolidSquad. Option B: Fluent Meshing Watertight Workflow
When you cannot use SOLSH190, the "SolidSquad" relies on three official ANSYS methods:
Imagine analyzing a welded bracket: A thick, cast lug (solid elements) connected to a thin sheet metal plate (shell elements).
