GRAPHIC STRUCTURE: The Visual-Q4M is a indipendent Pre and Post-Processor Graphical User Interfaces (GUIs) for seismic 2D analysis with a simple and intuitive graphical interface using visual tools that, in running, it connect automatically to the calculation Quad4m code.
GENERATE: In Visual-Q4M all nodes and zones generate a working grid that represents the model to be analyzed. The geometry can be modified in every part with easy and graphics tools so as to represent in the best way the reality.
MATERIAL: On each zone of the grid it is necessary to introduce the mechanical and seismic characteristics in order to perform a congruent calculation and to define accelerations in output to be interpreted.
BOUNDARY CONDITIONS: The boundary conditions in a numerical model represent the boundaries of the model. They can be real (really exist) as cavities, excavations etc... and artificial, and thay are used to define the numerical model. In the latter case it is important to use measures to avoid unpleasant reflections and refractions that are not real.
ANALYSIS: The calculation on the model is automatic. The Visual-Q4M hooks up to the Quad4m code in the background without using the DOS system.
GRAPHICS: Each calculated information can be represented with various items plot on the grid model. Furthermore, it is possible to plot the accelerations (velocity, displacements, spectra, transfer functions, etc.) for each node monitored during the calculation.
