GlassFiles vs 3D Topology Optimizer

GlassFiles is a fast, clean, and powerful archive app designed for iPhone. Open and extract 7 archive formats — ZIP, RAR v4/v5, 7Z, TAR, TAR.GZ, TAR.BZ2, and TAR.XZ — with a modern, handcrafted glass interface. WHAT MAKES GLASSFILES DIFFERENT: 7 Archive Formats — More than any comparable iOS archive app Multi-Part RAR Support — Automatically detects and resolves .r00, .r01, .part1.rar split archives Intelligent Format Detection — Reads binary magic bytes instead of relying on file extensions Streaming Extraction — Processes archives without loading them entirely into memory In-App Archive Preview — Browse archive contents before extracting Security-First — Path traversal protection on every extraction Glass Design System — Frosted surfaces, spring animations, and haptic feedback PRO UNLOCK: A one-time purchase enables batch extraction, background processing, and unlimited archive support. No account required. No ads. No tracking.

3D Topology Optimizer reduces the weight of a 3D part without sacrificing its strength — entirely on your device, with no cloud upload required. Load an STL model, mark contact surfaces, applied loads (forces and moments), and functionally important faces that must never change. The app then runs a real finite-element simulation and a SIMP topology optimization directly on iPhone, iPad, or Mac to determine which material actually contributes to strength and which can be removed. FEATURES • Automatic hole detection — cylindrical bores are recognized and automatically protected from the optimizer • Calculated entirely on-device — your geometry and load cases never leave your device • High-resolution STL export for 3D printing or CNC machining • Built-in parametric templates (bushings, brackets) to get started without any CAD file • Wireframe and shaded 3D viewer with axis indicators for precise face tagging WHO IT'S FOR Engineers, product designers, makers, and students who design 3D-printed or CNC-machined parts and want a fast, private way to see where material can be safely removed before committing to a print or a machining run. All calculations are a simplified, linear finite-element approximation and do not replace certified FEA software or review by a qualified engineer. Always verify results independently before manufacturing load-bearing parts.
