Creating a Simulation Mesh in PoligonSoft

A high-quality mesh is the foundation of trustworthy casting simulation. This page teaches visitors how to import CAD, generate an automatic tetrahedral finite-element mesh, check quality, refine critical areas, stay inside element limits, and use symmetry to reduce simulation cost without losing engineering clarity.

From CAD import to validated mesh.

The page should behave like a learning environment, not a long flat article. Each stage reveals a technical idea through a short explanation, animated graphic, and interactive control.

01

Mesh Generation

Show the visitor how a CAD model is imported and converted into a finite-element tetrahedral mesh. Use a scroll animation from clean CAD surface to inner tetra elements.

02

Mesh Quality

Explain that the first mesh is only the starting point. Users must inspect element size, shape, skewness, aspect ratio, thin walls, and weak geometry zones.

03

Optimization

Introduce the 500,000-element free workflow concept, then teach local refinement and symmetry as practical ways to keep accuracy and reduce computation.

Interactive mesh lab

Let users feel the mesh tradeoff.

Move the element-size slider to update estimated element count, quality score, compute load, and convergence confidence. This is an educational schematic, not a fixed benchmark.

Thin section
Needs local refinement so the wall is not represented by too few elements.
Quality outliers
Detect weak angles, distorted shapes, and mesh cells that may reduce result confidence.
Bulk area
Can remain coarser when geometry and thermal gradients are simple.

Mesh Density Controller

Use this module as an interactive infographic on the page. It teaches that finer mesh improves detail but increases element count and solve cost.

Quality dashboard

Turn invisible mesh risk into visible evidence.

Mesh quality should not be explained only with text. Give visitors a dashboard with histograms, pass/fail cards, and a 3D-style quality overlay.

Aspect Ratio / Skewness Histogram

Bars toward the right represent weaker elements. The page can animate these bars after mesh generation, then show local refinement reducing the risky outliers.

Explainer Tabs

Too coarse a mesh can miss important geometry and temperature gradients. Too fine a mesh increases memory use and calculation time. The right mesh is purposeful, not simply dense.
Aspect ratio describes how stretched an element is. Lower, more balanced shapes are generally preferable for stable numerical behavior.
Thin sections often need local refinement because a global mesh may not place enough elements through the thickness to capture behavior reliably.
Fillets, chamfers, and thickness transitions should be captured when they influence flow, hot spots, shrinkage risk, or stress concentration.

Educational Convergence Chart

Use this chart to show the learning idea: results usually stabilize as mesh refinement becomes sufficient. Replace the sample curve with real PoligonSoft project data when available.

Free limit + symmetry

Stay smart under the 500,000-element target.

Use this section as the “hack” moment: symmetry can reduce the active simulation volume and help users spend the element budget where it matters most.

Where to spend mesh detail

Thin wall Hot spot Bulk zone

Best-practice decision tree

First reduce unnecessary global density, then use symmetry if the part and boundary conditions allow it. Avoid simply deleting important detail.
Add local refinement only around the thin wall or transition. This protects accuracy without inflating the full model.
Use automatic quality analysis, geometry correction, and local mesh adjustment before moving to simulation.
Capture them when they influence hot spots, flow, shrinkage, wall transition, or stress. Simplify only non-critical small features.
Motion & media blocks

Use GIF, short video, and scroll animation.

These media modules are included as working placeholders. Replace them with real PoligonSoft capture, tutorial video, or rendered product footage.

GIF loop: CAD → mesh → quality overlay

Place this near the top of the page or inside the mesh-generation section. It gives instant visual meaning before users read the detailed tutorial.

[Video Placeholder: poligonsoft_mesh_page_assets/mesh-preview-video.mp4]

Small video: final mesh preview

Use a 10–20 second screen recording of PoligonSoft rotating the final mesh, showing element count, and opening the quality panel.

Long-form content architecture

How to make a 60,000-word page readable.

Do not show sixty thousand words as one article. Use expandable chapters, search, sticky navigation, glossary cards, and expert drawers.

A

Visible layer

Short, crisp explanations for fast readers: headings, one-minute summaries, diagrams, and CTAs.

B

Deep layer

Expandable technical sections covering element quality, convergence, refinement, symmetry, and troubleshooting.

C

Proof layer

Reference panels, footnotes, source links, practical examples, and real PoligonSoft screenshots.
