ANYstructure

ANYstructure is the ultimate steel structure design tool for plate fields and cylinders!
Weight, weld and cost optimization.
Calculations are based on DNV standards and recommended practices.

What's new in 6.1.1

  • Urgent fix for cylindrical shell updates where hidden cone defaults could overwrite radius, ring spacing and shell lengths.
  • 3D CAD export dialog now includes a transformation scale input and keeps intermediate IFC files unchecked by default.
  • 3D solid export can write one joined IFC product without building a heavy global boolean union.

What's new in 6.1.0

  • Simplified GUI input option.
  • Weld/weight optimization.
  • Cost optimization.
  • 3D representation of panels/cylinders.
  • Improved Semi-analytical buckling implementation.
  • Optimization of stiffened plate with girder.
  • Bug fixing.
  • Export 3D shell model.
  • SciPy Differential Evolution Optimizer added.

What's new in 6.0.3

  • New buckling method: Semi-analytical buckling for flat plates.
  • Updated ML buckling to numerical instead of classification. Improved accuracy of the neural network.
  • Updated color coding option.
  • Implemented extended testing regime.
  • Started work on separating calculation code from the GUI.
  • Python 3.14 supported.
  • Addressed some calculation bugs.
  • Updated API.

Development setup

ANYstructure is currently maintained as a Python package named anystruct. The GUI can still be launched through the ANYstructure console command after an editable install.

Recommended local setup:

python -m venv .venv
.\.venv\Scripts\Activate.ps1
python -m pip install --upgrade pip
python -m pip install -r requirements-dev.txt
python -m pip install -e .
python -m pytest

Launch the desktop app after installation:

ANYstructure

Dependency groups are also available for focused installs:

python -m pip install -r requirements-core.txt
python -m pip install -r requirements-ml.txt
python -m pip install -r requirements-excel.txt

Equivalent package extras are exposed as core, ml, excel, dev, and all. The default package install still includes Excel and ML dependencies for backwards compatibility.

Excel project import requires a local Excel installation and is not expected to run in basic automated tests.
The external Excel-sheet DNV PULS calculation workflow has been removed from this release; ML-CL remains available.

The following is calculated:

  • Minimum plate thickness (DNV-OS-C101)
  • Minimum section modulus of stiffener/plate (DNVGL-OS-C101)
  • Minimum shear area (DNVGL-OS-C101)
  • Buckling (DNVGL-RP-C201)
  • Buckling strength of shells DNV-RP-C202
  • Machine learning buckling, PULS based
  • Semi-analytical buckling
  • Fatigue for plate/stiffener connection (DNVGL-RP-C203)

Compartments (tank pressures) are created automatically.

Pressures on external hull (or any other generic location) is defined by specifying equations.

You can optimize cylinders, single plate/stiffener field or multiple. Geometry of double bottom can be optimized.
