Ansys Solidsquad Top Now

You cannot run the full SolidSquad TOP sequence inside standard Ansys Mechanical (the Workbench GUI) alone. You must use a Command Snippet (Workbench) or the APDL Classic interface.

When you view results in Workbench, the shells and solids will have different stress values at the interface.

To prove the value of the Ansys SolidSquad TOP, consider a cast aluminum control arm.

Verdict: The 50% increase in solve time yielded a 7% more accurate stress prediction and eliminated contact chatter that required 5 sub-steps to resolve. ansys solidsquad top

If you are using the classic interface (pre-Workbench), the command is simply typed at the > prompt after meshing:

/prep7
et,1,solid187
vm esize,1
vmesh,all
solidsquad,all,0.85,top
*get, max_shell, elem, 0, num, max
et,2,shell281
type,2
emodif,all
eplot

! Select all solid elements (Assume SOLID187 is active)
esel,s,ename,,187

! Issue the SOLIDSQUAD command to generate Shell elements on the selected solids
SOLIDSQUAD, ALL, 0.85, TOP


! Explanation:
! ALL = Apply to all selected solid elements
! 0.85 = Aspect ratio limit (elements exceeding 0.85 will be split)
! TOP = Operate on the topological skin (the "top" layer)
 You cannot run the full SolidSquad TOP sequence

! Define a quadratic shell element (SHELL281)
ET, 10, SHELL281

! Assign that shell type to the newly created surface elements
TYPE, 10
ESEL, S, ENAME, , 151   ! 151 is the default shell element created by SOLIDSQUAD
EMODIF, ALL, TYPE, 10

In the rapidly evolving landscape of computer-aided engineering (CAE), the demand for integrated, intelligent, and collaborative simulation platforms has never been greater. Engineers no longer work in isolation; they operate within cross-functional teams, balancing performance, manufacturability, cost, and sustainability. Enter Ansys SolidSquad TOP—a conceptual yet highly plausible evolution of simulation technology. By combining the proven solvers of Ansys, the collaborative framework of a "SolidSquad" team environment, and the rigorous mathematical discipline of Topology Optimization (TOP), this unified platform promises to revolutionize how products are conceived, validated, and refined.

When you generate an automatic tetrahedral mesh on a complex imported CAD part, Ansys creates a cloud of SOLID187 (10-node tetrahedrons). While fast, tets can cause "volumetric locking" in nearly-incompressible materials (like rubber) or fake stress stiffening.

The SolidSquad TOP method performs three distinct steps: Verdict: The 50% increase in solve time yielded

The result? You get the meshing ease of tets with the bending accuracy of hexahedrons on the surface.
