Postprocessing and Visualization

LowLevelFEM provides built-in postprocessing and visualization tools based on Gmsh. Results can be displayed interactively, exported, probed at arbitrary locations, or evaluated along user-defined paths.

Typical workflow:

u = solveDisplacement(problem, load=[force], support=[bc])
S = solveStress(u)

showDoFResults(u)
showStressResults(S)

openPostProcessor()

The most commonly used visualization functions are:

• showDoFResults – displacement and other nodal degrees of freedom
• showStressResults – stress components and equivalent stress
• showStrainResults – strain components
• showHeatFluxResults – heat flux fields
• showElementResults – element-wise results (e.g. stress, strain, heat flux), which may be discontinuous across element boundaries
• plotOnPath – evaluate and plot results along a user-defined path
• probe – evaluate field values at arbitrary locations
