Solves its Analysis Bodies under one Load Case for small, linear-elastic deformation, on the immersed solver: the parts stay as they are, no mesh to build.
The result carries the displacement, von Mises stress, stress and strain components and principal values as fields to drape or reuse, and #SurfaceStress, #Mean (mean cell stress), #PNorm (grading stress, a p-norm of the cells) and #MaxDisplacement as numbers; #Mean and #PNorm are levels of the result cells to grade a field by, not the part's stress figure.
#SurfaceStress is the typical surface stress: the level 99 % of the model's surface stays at or below, by area, leaving out the surface within two result cells of a Support's faces, where a support's edge concentrates stress that belongs to the way the part is held more than to the part; each point of the surface reads the result cell that holds it. It is not the peak: peaks at sharp inner corners are not settled by any solver. It is not given where a thin wall joins solid material of its own body (a boss, a Keep solid region): there the analysis does not read stress within 10 % of fine reference models yet (a bolted box read 20.5 % high against CalculiX), and the card says so.
The deflection there is given but not validated yet: it moves with where the analysis' cells fall on the part (measured up to 17 % high on a bolted box), and the card says so too; so is the deflection of a part joined to another body that carries load with it (a plate) — a body that only holds the part (a Support's body, like a steerer or an insert's tube) is not another body. On a finished part (added material on its wall, a Reinforcement's result) the deflection is within 4 % and the stiffness ratio behind the gain within 4 %, as measured against fine reference models, and the card says so.
The von Mises stress is drawn up to the typical surface stress, or where none is given up to the highest value drawn; the cells next to the Supports show striped on the part and the legend names them.
The Analysis Bodies to solve, each with its Solid, its material and how it is treated: one body, or a List of them. The result covers every body: the drape, SurfaceStress, Mean, PNorm and MaxDisplacement.
Optional list of Contact, Tie and Bolted Joint connectors between the bodies. Bodies that touch are not joined unless a connector joins them.
The Load Case: its loads and supports, in world axes.
Precision — Resolution = TARGET ELEMENT COUNT (number of octree cells). Used while By cell size is off, or Cell size is 0: the band cell-size is searched (bisection) to produce ~this many material leaves, so coarse/large parts and fine/small parts auto-scale to a similar cost. Set Cell size instead for an absolute size.
Precision mode (By cell size): OFF (default) → Resolution (target element count) drives the octree refinement; ON → Cell size (absolute mm) drives it and Resolution is ignored.
Precision (Cell size): absolute octree band leaf size in model units (mm), used when By cell size is ON. Decoupled from domain size, so a thin member gets ≥3 cells across when the cell size ≤ member/3.
Radius around each support position whose nodes are fixed (a patch, not a single node, so a fixed interface doesn't read as a stress singularity).
The exponent of the grading stress #PNorm: the higher, the nearer it comes to its cap, the 95th percentile of the cells (~4–8 typical).
Element basis order (simulation setting). 'linear' (p=1) is accurate with ≥3 cells across a wall — the default; 'quadratic' (p=2) needs far fewer cells for the same accuracy, suited to bending-dominant thin shells / beam-type structures.
Linear solver (simulation setting). 'default' auto-selects by order + size; 'direct' is robust but memory-heavy; 'iterative' uses less memory (for high resolution / quadratic).
Values the block gives besides its output. The editor lists them under Properties, and an input can read one by reference.

Von Mises stress across the model, drapeable and 0 outside the material; it can drive a variable wall thickness.

Typical surface stress (99 % of the surface stays under this): the level 99 % of the model's surface stays at or below, by area, the surface within two result cells of a Support's faces left out; each point of the surface reads the result cell that holds it. Not the peak: peaks at sharp inner corners are not settled by any solver. Not given where no surface lies away from the Supports, nor where a thin wall joins solid material of its own body (a boss, a Keep solid region): the result card says why.
Mean cell stress: the average von Mises stress over the material's result cells, by count. Not the part's stress figure: that is SurfaceStress.
Grading stress (p-norm): a p-norm of the von Mises stress over the material's result cells, each capped at the 95th percentile of them first (the Stress p-norm input is its exponent), so never above that percentile — a smooth level to grade a field by. Not the part's stress figure: that is SurfaceStress.
