FER/View is a color interactive graphics visualization program which displays two-dimensional and three-dimensional time-dependent numerical simulation static or dynamic results. FERView is developed by using C++ language with the support of OpenGL graphical library on the environment of Microsoft Visual C++ developer studio and SGI station respectively.

With the techniques of object-oriented programming and OpenGL programming as well as some new geometrical algorithms, it produces the high image quality and allows to visualize and to operate very easily the large amounts of data produced in the analysis results.

I. Installation

• PC version:


a) platform : PCs with Window 95, 98 or Window NT

b) extract files Ferview.zip (FERView.exe, forming.rst, ...)

c) run FERView.EXE

Note : If the message box "not find the file .DLL " appears, download the file Opengl95.exe from: ftp.microsoft.com run Opengl95.exe and copy the files Glu32.dll and Opengl32.dll to the windows/system

• SGI version :


a) platform : SGI workstation Octan or O2,

b) using command %uncompress fervsgi1.tar.Z

c) using command %tar xvf fervsgi1.tar

• Available not only for the general finite element static or dynamic analysis, but also for the model with the variable numbers of node and element during the computation (i.e. using remeshing method),
• Node, Element mesh and Geometry shape plot,
• Display mesh deformation. All visualization techniques use the deformed mesh with undeformed mesh overlay.
• Display different color according to the element property,
• Display node, element or material number,
• Contours, Iso-line, Iso-surface and Vector plot,
• Display minimum and/or maximum values of data for the current time step or for all time steps.
• Change the color division number for contour or iso-line etc. plot,
• Cutting plane plot,
• Add or cancel light effects,
• Animation in any case of displays mode,
• Display some selectted elements for display,
• Display time history of multiple data,
• Display the distribution curve of data on a line path,
• Mouse operation for rotation, pan and zoombox as well as node picking,
• File operation about saving and printing images and curves (.xls).

Ferview uses its own binary file format(.rst). However, You can use the file translator functionality of Ferview to change your results (ASCII file with an extension .asc) which must have the format as follows :

200 // file type, 200 means 2D, 300 means 3D, 250 means shell element

2D test example! // job title

-------------- Nodes -------------------

*note:

1). About the name of display items (UX,...), only the deplacements are limited as UX, UY and UZ.

2). For the demo version, the element type is limted as : 3 or 4 node elemnt for 2D, 4 or 8 node for 3D.

3). For the demo version, if you use the translator command (translate the result file from ASCII (.asc) to Binary file (.rst), the number of node is limited under 100.
