Technical Overview

Unlock the power of simulation data with HOOPS Access, an object-oriented C toolkit from Tech Soft 3D. Designed for developers, it streamlines the process of reading, querying, and writing CAE input and result files from a wide array of industry-standard solvers.

Effortlessly access and manipulate complex datasets, with broad format support as shown below. Formats in blue offer full read/write capabilities for seamless integration into your workflows.

Through the unified API of HOOPS Access, developers can seamlessly explore and process complex simulation datasets from any supported solver, without needing to manage the unique details of each format’s internal structure.

For example, HOOPS Access enables the following core workflows:

  • 🔍 Read and query solver results
  • 🧠 Access structured finite element data
  • ⚙️ Navigate multi-step and multi-domain analysis including static, transient, modal, and nonlinear simulations
  • 🛠 Write data back in any of the supported output formats, allowing seamless conversions to facilitate complex simulation pipelines.
  • 🔗 Integrate directly into existing applications : CAE viewers, meshing frameworks, design optimization, machine learning, …

Supported simulation data is designed to be comprehensive, and includes:

  • Node data:
    • Coordinates
    • Node IDs (including user node ID)
  • Element data:
    • Connectivity
    • Element types (lines, triangles, quadrilaterals, tetrahedra, pyramids, pentahedra, hexahedra, polygons, polyhedra)
    • Element FEA types (solids, shells, beams, trusses, membranes, plates, springs, dashpots, rigid bodies)
    • Element IDs (including user element ID)
    • Material IDs
    • Property IDs
  • Coordinate systems
  • Materials and physical properties
  • Boundary conditions (loads, constraints)
  • Units
  • Metadata
  • Results data:
    • Scalar results
    • Vector results
    • Tensor results (including symmetric tensors, e.g., stress)
    • Complex and real fields
    • History results
    • Mode numbers
    • Time steps
    • Load factors
    • Solver metadata
  • Auxiliary model information:
    • Load and constraint cases
    • Element material and physical properties (if available)
  • Results location:
    • Node points
    • Element centroids
    • Element nodes

HOOPS Access is free to evaluate for 60 days on Windows x64 and Linux 64-bit platforms.
