From design volume to independently verified result

A practical quick start for building a clean topology-optimization study inside Blender.

Use one closed manifold mesh that represents the maximum volume the generated structure may occupy. Apply object scale and repair non-manifold geometry when possible.

Choose the design volume

Select the source object and confirm that it represents the full space available to the future structure.

Build and approve the Uniform Mesh

Choose the engineering mesh density, build the uniform mesh, inspect it, and approve it. Loads and supports are assigned to this predictable mesh rather than irregular source topology.

Choose material and Print Density

Select PLA, ABS, PETG, ASA, PA12 / Nylon, or Polycarbonate. The profile supplies a conservative starting point; Target Safety Factor remains adjustable.

Define fixed areas

Select the faces representing real clamps, bolts, bonded regions, or supports. Use enough surface area to describe the real attachment instead of constraining an accidental point.

Add loads and load cases

Add up to 10 Force, Pressure, Bearing, Moment, or Remote Force conditions. Define magnitude, direction, and case.

• Loads with the same case number act simultaneously.
• Different case numbers remain separate structural requirements.

Generate the structure

Choose Engineering Fidelity and press Generate Design. GaudiTopo performs pre-analysis, Target Safety Factor Search, and SIMP topology optimization. The viewport shows the density surface, stress utilization, progress, and current state.

Verify the delivered mesh

With Independent Verification enabled, GaudiTopo re-voxelizes the final surface and solves a separate FEM problem. You can also use Verify Result Mesh later on the active result.

Important engineering limitation

GaudiTopo is an engineering exploration and screening tool, not a certification solver. FDM anisotropy, layer adhesion, defects, print orientation, temperature, wall strategy, and machine calibration can dominate real-world strength. Physically validate every load-bearing manufactured part.
