To provide high quality product, WaveFEA had released WaveFEA 2017. This document highlights new features and provides information that is useful while using this software.
List of new features in WaveFEA 2017:
In run PPFA analysis visibility of showing the intermediate results for COMP STATUS
Currently WaveFEA shows a contour of von Mises stress (an intermediate result) when nonlinear solution is running. For PPFA solutions (when laminates are present and NLCOMPPLYFAIL=ON), a contour of COMP STATUS should be displayed. Users need to be able to see the evolution of damage; a lot of users want to be able to stop the analysis once 100% damage is achieved.
Easy way to control the number format for the contour legend
This feature will affect the results view (single browser node), but the user can change the result type. Therefore, if the user sets the preferences to "decimal" and "2" places, but the results are smaller it will be forced to scientific notation. This doesn't mean that the preference in the dialog changes to scientific. The dialog should still reflect the user's choices. However, because the result would end up with a legend showing all zeros, we convert to scientific notation. All values of the legend are shown in the same format. So if one value is not able to be displayed, they all gets converted.
All type of connectors have "Next" and "Previous" options
Previous and Next options streamline creation of multiple connectors. Currently they are available for Rod, Cable and Spring connector types. They should also be supported for Bolt and Rigid connector types.
Value of the applied load is shown in the tooltip when user hover over the Load node in the browser
As user hovers over the Load node in the browser, the value of the applied load should be shown in the tooltip.
Bearing load glyph directions will always be normal to the surface
Bearing load always be normal to the surface to which it's applied (at each node). Hence, the load applied in the correct direction at each node, and the glyphs also show this direction accordingly.
Improved handling of secondary material IDs in the advanced options of the shell property
- Add checkboxes (unchecked by default)
- When checkboxes are unchecked, the material selection dropdowns are disabled, greyed out, and set to the main membrane material from the basic dialog (except for Membrane-Bending (MID4), which is set to blank)
- When the membrane material changes, the greyed out drop-downs follow the change
- When the checkboxes are selected, the “advanced” materials become independent from the Membrane material.
Response spectrum analysis support
A response spectrum is simply a plot of the peak or steady-state response (displacement, velocity or acceleration) of a series of oscillators of varying natural frequency that are forced into motion by the same base vibration or shock. The resulting plot can then be used to pick off the response of any linear system, given its natural frequency of oscillation. One such use is in assessing the peak response of buildings to earthquakes. The science of strong ground motion may use some values from the ground response spectrum (calculated from recordings of surface ground motion from seismographs) for correlation with seismic damage.
Response spectra are curves plotted between maximum response of SDOF system subjected to specified earthquake ground motion and its time period (or frequency). Response spectrum can be interpreted as the locus of maximum response of a SDOF system for given damping ratio. Response spectra thus helps in obtaining the peak structural responses under linear range, which can be used for obtaining lateral forces developed in structure due to earthquake thus facilitates in earthquake-resistant design of structures.
