For a solution or sequence of solutions, errors related to the solution quality may be determined by the following four checks: global (energy norm), deformed shape, fringe continuity and the local data convergence (including how limits may be computed to estimate error).

After the solution is complete, the final p-level of each solved element may be displayed/tabulated:

StressCheck supports the use of certain intrinsic functions and mathematical expressions (FORTRAN or Mathematica conventions) when defining parameters and/or formulae. For example, "sin(x)" for sine(x), where "x" is a user input in radians.

Yes, it is very simple to define formulae for live results processing purposes. Formulae may involve expressions of StressCheck's standard engineering functions, such as Sx, Sy, Ex, etc. as well as formula subexpressions (i.e. formula names contained within {} characters) and parameter names.

There are a number of variables that may affect fringe plot rendering rates, especially if the cutting planes option is enabled. Though, models with large numbers of elements and/or solution degrees of freedom (DOF) will cause the rendering to perform slower in general.

The default for plotting/extractions is Cartesian coordinates (X, Y, Z). However, StressCheck supports the plotting/extraction of results in Cylindrical coordinates (R, T, Z):

For certain objects, the integral average of one or more engineering functions (e.g. Sz in the Global coordinate system) over the length/area of the selected object(s) may be computed by enabling the Average button in the Point extraction tab:

Each Solution ID requires a unique Load ID and Constraint ID. Some users wish to combine the results of two or more load cases together, such as axial/bending or mechanical/thermal load cases, and this may be accomplished via the StressCheck Calculator (Functions: Calc):

In general the range when entering Offset, P1 (Min/Max) and P2 (Min/Max) inputs for object generation, or object boundary extractions in the Points tab, is typically normalized to [0,1]. However for some geometries, such as spheres, cylinders and cones, the P1 (Min/Max) and/or P2 (Min/Max) inputs may be conveniently entered in degrees.

The StressCheck Resultant tab allows the user to integrate the tractions over the edges (2D) or faces (3D) of the elements to calculate the resultant forces Fx, Fy, Fz and moments Mx, My, Mz.  This can be done over selected edges/faces, or over entire element boundaries.
