Fachwerk3D - Changelog ---------------------- version date changes 0.45 22.02.17 New function - Add-in: Export background drawing (*.bgd) - Move nodes by mouse and snap background drawing Details - point size reduced for background images, assumption 1:50 with 150dpi - compressed background drawings bgd.gz / csv.gz - Add-in: transformations of model and background drawing Scaling of individual axes, change of axes y-z, rotation around z-axis - system tab in about window 0.44 06.03.16 Details - adaptive tolerance for equilibrium checks 0.43 31.01.16 New function - import planar Fachwerk file *.fwk - Error message if a member has zero length - export csv including results Details - in Mac OS X menu bar anchored to the top of the screen - zero force members green - fallback language English (instead of German) - Ant based compilation and packaging. - Removal of unused parts of math library colt, that complicate compilation. 0.42 30.12.15 New functions - Image as background 0.41 13.05.10 Details - Alternative algorithm of automatic model reduction enhanced. - Linux desktop integration: menu entry, file associations 0.40 29.11.09 New function - Add-in: Automatic reduction of model (experimental) Details - Status line shows member length - New commands "delete (set) unstressed members" and "delete loose nodes" added. - "fachwerk3d drawing.dxf" loads the dxf. - Start parameter --safe_mode. To be used file dialogue does not open (Windows only) 0.32 23.05.09 New function - Improved keyboard control Details - Additional key accelerators - (Shift-/Ctrl-) Arrow keys move/turn the model view. 0.31 1.12.07 New function - Status field shows the statical indeterminacy. Details - Bug with sliding bearings fixed. Caused fachwerk3d not to solve models, when the blocked direction of a sliding bearing was not parallel to a coordinate axis. 0.30 26.08.07 New functions - Propose member forces Based on elastic calculation. Assumption: EA,c = 10 EA,t (iterative calculation) - Find node position A node will be moved along a straight line, until a required member force is achieved. Details - Rare bug in the solver fixed. Caused message "Contradiction" even though model was ok (only when mechanism check switched off). - Deletion of members and nodes without reconfirmation, if not set / connected to members. 0.22* 18.02.07 Details * not released - more functions accessible by function keys 0.21 24.09.06 New function - Mouse wheel zooming Details - Labelling of the load and bearing force arrows - Print System shows mechanism. - Error message shown in status line if saving fails. 0.20 28.07.06 New functions - Kinematic method (mechanisms) Fachwerk3D additionally applies the kinematic method to the model. If the model is instable *and* does not respect equilibrium conditions, an according mechanism is drawn. This feature simplifies finding errors in statically indeterminate models. Details - enhanced solver - number of statical indeterminacy shown on console output 0.10 13.11.05 New functions - Pan middle mouse button or Ctrl-key and left mouse button - Scaling of loads - Help Details - Verbose console output - Source code cleanup 0.05 3.07.05 not published - Split members 0.04 20.04.05 New functions - Status line for members In addition to the member force, its components are displayed. Look The default LookAndFeel is the one of Java 1.4, also for Java 1.5. Details - File name in title of program window. - Keyboard quick access: save, print and reset of calculation. - Member and Node property dialogues The most frequently used field has the focus after opening the dialogues. Escape key aborts the dialogues. - Node property dialogue Enter key puts the cursor in the next field resp. closes the dialogue (=OK). - Open file dialogue The first time a background drawing is loaded, the dialogue shows the directory of the .fwk model file. Previously the users home directory was shown instead, when the program was started by clicking on a fwk file. 0.03 5.12.04 Usage and Look - The view and the zoom do not change when a new 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 dialogue. - The input data can be exported into a table that can be opened by any spreadsheet application. Useful for finding input errors. - The LookAndFeel has been changed, due to the new standard look of Java 1.5. It was hard to see if a button was pressed. The previous look can be obtained using the option "fachwerk3D --look Java". Details - Keyboard quick access: F9 calculate, F11 select node, F12 select member. - Bug fixed: A load was not shown in the status line if both the x- and z- components were equal zero. - The function "create node (snap)" gets deactivated when clicking somewhere else than on a background point. - Member property dialogue: Enter has the same effect as a click on the "change"-button. 0.02 26.10.04 Several features ported from Fachwerk0.10: - Background drawings (3D): dxf, bgd, csv - Creating nodes snapping to a background point - transformations: scale or move the strut-and-tie model - transformations: scale or move the background drawing - Keyboard quick access: F5 New node, F7 New Member, DEL, etc. - Colt version 1.2.0 used (instead of 1.1.0). 0.01 21.09.04 Initial publication of the program (GPL) 0.01 15.08.04 First internal release of Fachwerk3D - Based on Fachwerk 0.09 (with a small enhancement for ver. 0.10)
