From 2D Sections to Full 3D Modeling & FEM Design

With DeepEX, engineers can seamlessly transition from 2D to 3D modeling using powerful, integrated modules. Let’s break down how 3D Frame Analysis and the 3D FEM Engine complement each other.

Start with DeepEX 2D

All 3D features build on the DeepEX 2D foundation. Design your 2D excavation section with walls, supports, and staging. Then expand it into the 3D realm.

DeepEX 3D Frame Analysis Module

Convert your 2D section into a full 3D model for spatial coordination, structural checks, and cost estimation.

Key Features:

Automatic 3D generation from 2D sections
Full control of support layout and geometry
Analysis based on 2D methods (LE, Non-linear, 2D FEM)
Structural checks for supports and walers
DXF import for site data (buildings, roads, etc.)
Cost estimation and building damage assessment tools

DeepEX 3D FEM Analysis Module

An extension of 3D Frame, this module introduces a full 3D finite element engine. Perfect for projects that demand detailed soil-structure interaction.

Key Features:

One-click generation of 3D FEM mesh from 3D Frame
Automatic staging, support locations, and geometry
Visualize stresses, displacements, and soil deformation
Include TBM tunnels and check tunnel-induced wall stress
Model base piles, deck beams, and more
Run full structural checks within the FEM environment
