Traglast is a small finite-element solver for linear static problems with 2D structures. You can also calculate
boundary loads of steam-beam-constructions by using a nonlinear algorithm. Currently Traglast supports 2D-beam-elements
with joints, joints only at one end of the beam and joings on both sides of the elements.
To create your structures Traglast provides a simple GUI for pre- and post-processings based on a MFC GUI. SO you can create your own models, start the calculation and view your primary and secundary results.
Traglast uses the GPL license.
At first get the windows-installer at Sourceforge
and install Traglast for win32. Now start it and you should see the Win32-GUI for traglast:
To create a simple model select Struktur->Koordinaten erzeugen->Knoten erzeugen. Enter at first two coordinates at 0.0, 0.0 with a boundary condition in x, y and around the x axis. Now create another node at 10.0, 0 withound any boundary conditions.
Create a material:
Open Struktur->Material->Material erzeugen and a dialog for the material input will be opened. Now enter the data for your material. You can also define a plastic moment for the boundary load computation.
Select Struktur->Elemente->Numerisch to open the Create-Element-dialog. Enter the start and the end-node, choose the number of elements to create. At last select your material and close the dialog by pressing OK.
Select Strutur->Lasten->Einzeleinwirkung erzeugen to open the loading dialog. Now select the direction of the load, enter the value and select a node for your loading. Close the dialog by pressing Ok.
Start the calculation
Select Berechhnung->Berechnung starten to open the calculation-dialog. Now click on Optionen and select "Berechnung nach Theorie 1. Ordung". Click on OK and click on Berechnung starten. If everything was right you should see a dialog withe the estimated time for your calculation.
Check your results
Select Berechnung->Ergebnisse and select each possible point to see the deformation and the inner forces of your structure.

You can download Traglast for Win32 at Sourceforge. A linux version is in planning, but not finished yet.
