A really easy web-based platform for
mechanical analysis on the cloud

Put the way we (you) perform
computer-aided engineering
upside down.

Design on the web. Run on the cloud.
Always available. Always updated.

 

  Create a free account

Do it yourself

Perform mechanical analysis of your products without installing expensive and hard-to learn software, nor buying expensive and one-time-use hardware, nor recurring to expensive experts (yet).

Get a PDF

Generate an engineering-grade report with your name and your logo that gives the percentage of resistance your product has under working loads, supported by the finite-element theory.

Share your work

Your projects and reports can be shared with your colleagues, suppliers and/or customers. Keep all your work always available and access them even from your tablet or smartphone.

UNIX Philosophy

Fifty years worth of knowledge

Current

  • It is a web-based interface for finite-element analysis running on the cloud based on a separation of the front-end from the back-end.
    • No need to install new software.
    • No need to install new hardware.
    • Both the front-end and the back-end are automatically updated and synchronized without needing user intervention.
  • Solves the linear steady-state displacement-based variational finite-element formulation of the linear elastic problem of structural mechanics.
    • No need to specify displacement conditions for every direction.
    • No need to completely restrict rigid-body motions.
    • External loads can be given as pressure, total forces or as the projection of the stress tensor over the outward normal of faces.
    • Volumetric loads (weight, centrifugal or general expressions) can be applied.
  • CAD models can be provided in either BREP (recommended), STEP or IGES.
  • Different users can have read, write or admin access to projects.
  • Each project maintains a full history of changes, and and it can be reverted to any particular revision using Git.
  • Uses only free and open source libraries and programs for the back-end:
    • PythonOCC (which itself relies on OpenCASCADE) for analyzing and processing the CAD models.
    • Gmsh for the mesh generation.
    • Fino (developed from scratch by Seamplex) for the solution of the elastic problem (using GSL and PETSc as the main libraries).
  • Different meshing algorithms can be selected (Delaunay, Frontal or MeshAdapt).
  • Either first or second-order tetrahedral grids can be generated.
  • Provides a comprehensive material database with the possibility of adding new materials with tailored properties.
  • Post-processing can be done online (basic) or offline (advanced) by downloading a VTK file with detailed results (displacement fields, Von Mises and principal stresses).
  • Generates high-quality PDF reports (using LaTeX) with integrated revision control (using Git).
  • Screenshots can be taken at any moment to be included either in the PDF report or in other customized media (i.e. presentations).
  • Sensitive data is encrypted both during transfer (TLS) and at storage (AES). User passwords are stored as salted hashes.
  • It has redundant, diverse and independent back-up copies of user data.
  • A simple tutorial illustrates the main CAEplex’ features.

Planned

  • More types of problem
    • Modal analysis.
    • Non-linear materials and deformations.
    • Heat transfer (both steady-state and transient).
  • Advanced meshing:
    • Both automatic and manual local grid refinement.
    • Hexahedral, prismatic and pyramidal elements.
    • Fine control of meshing options and parameters.
  • Support for assemblies and multi-material bodies.
  • Integration with Onshape. See this video for a preview.
  • Implementation of a community forum.
  • Improved mobility.
  • Stereo-Litography geometries (STL files).
  • Non-trivial spatial dependent (i.e. through a pointwise-defined temperature field) of material properties.
  • More complex boundary conditions for both loads and displacements.
  • Improved post-processing experience.
  • Customization of layout and colors.
  • Lightweight PDF datasheets with main results.
  • Community forum.
  • Detailed case studies.
  • Comprehensive help.

Long-term plans

  • More types of problem
    • Non-linear contact problems.
    • Computational fluid dynamics (CFD).
    • Electromagnetism.
    • Neutron transport and diffusion.
  • Multilingual support
