All releases of Fachwerk3D
Release Notes: This release improves the automatic model reduction algorithm. Linux users will benefit from desktop integration. The user manual has been enhanced and updated. It now covers the automatic model reduction introduced in the 0.4.x release. While the examples are two-dimensional, the feature also works in 3D.
Release Notes: This release adds a feature that allows semi-automatic strut-and-tie model creation: an optimization process eliminates inefficient members until the model is statically determinate.
Release Notes: This release improves usability on netbooks. It adds more key accelerators. (Shift-/Ctrl-) Arrow keys move or turn the model view.
Release Notes: The status field shows the statical indeterminacy. This release fixes a bug with sliding bearings.
Release Notes: Upon request, the program proposes member forces if the system is statically indeterminate. The calculation is linear-elastic and assumes a fixed ratio compression to tension stiffness. The algorithm works even if the system is unstable. The user still has to judge if the proposed member forces are reasonable for the given case. This release adds an algorithm that moves a node along a straight line until a required member force is achieved.
Release Notes: This release adds support for mouse wheel zooming. Force arrows are labelled.
Release Notes: This release adds a mechanism check algorithm. It is based on the theory of plasticity's upper bound (kinematic). Mechanisms are shown graphically, so finding missing members of an incomplete strut-and-tie model is simplified.
Release Notes: This release adds the help menu. Members can be split and loads can be scaled globally. The mouse can be used to pan the view of the model.
Release Notes: The status line information for members has been enhanced: in addition to the member force, its components are displayed.
Release Notes: This release improves usability issues. The viewing direction and zoom remain unchanged when a member is created or when the properties of a member are changed. A right click on a member or on a node opens its property dialog. The input data can be exported into a table that can be opened by any spreadsheet application. A bug in the status line has been fixed.
