FriComp

Purpose:

The FComp interface is used to display fringe component data on the model. It allows the selection of various scalar quantities like strains and stresses that can be fringed.

For shells and beams, such data is stored for different integration points through their thicknesses and cross sections respectively. Upon selecting a component to be fringed, further selection of data at a particular integration point can be made using a simple selection widget with options (Low/Mid/Upp/Max/Ave/Min/IPt/BPt).

By default LS-PrePost will fringe the maximum of all integration point data available.

Stresses and strains in d3plot are in the global coordinate system except when CMPFLG have been used. By default, LS-PrePost will plot the stress and strain as they are written to d3plot. The stress and strain can be plotted in Element, Global, Material or in a User specified coordinate system by changing the "d3plot/Elem/Glob/Mtrl/User" switch but this requires that both the d3plot and the keyword file have been read.

User data can be loaded using the User button and fringed. This can be from external third party software or element and nodal results output from the Output Interface in Post.
