A. Mesh (§2.7)
A. Mesh (§2.7)¶
Mesh tag mesh2. Built from explicit Free Triangular + Size nodes, i.e. user-controlled; the
report never prints the sequence-type label. Sizes are in nm.
A.1 Statistics¶
| Quantity | Value |
|---|---|
| Triangles | 120 917 |
| Edge elements | 1 879 |
| Vertex elements | 196 |
| Minimum element quality | 0.6378 |
| Average element quality | 0.9765 |
| Quality measure | NOT IN REPORT (§5.4 plots are labelled skewness) |
| Degrees of freedom | NOT IN REPORT |
Element type is triangular throughout — no quads, no mapped mesh.
A.2 Size nodes¶
Off in the report means the override checkbox is cleared, so the value is inherited from the
global Size node and the printed number is inactive. Active values in bold.
| Node | Level / selection | Max size | Min size | Curvature | Narrow regions | Growth rate | Predefined |
|---|---|---|---|---|---|---|---|
size Size (global) |
whole model | 10 | 0.001 | 0.25 | NOT IN REPORT | 1.05 | Finer, Custom |
size1 Size (reservoir boundary) |
Boundaries 195–196 | 5 | 0.025 (Off) | 0.25 (Off) | Off | 1.25 (Off) | Finer, Custom |
size5 Size (pore boundary) |
Boundaries 7–29, 31–152, 154–194 (sel. Nanopore) | 0.05 | 0.001 | 0.25 | NOT IN REPORT | 1.05 | Finer, Custom |
size6 Size (symmetry axis inside pore) |
Boundaries 3–4 | 0.075 | 0.04 (Off) | 0.25 (Off) | Off | Off | Finer, Custom |
size3 Size (reservoir domain) |
Domain 1 (Reservoir) | 2.8 (Off) | 0.04 (Off) | 0.25 (Off) | Off | 1.04 | Finer, Custom |
size2 Size (pore domain) |
Domain 2 (Nanopore) | 0.1 | 0.004 (Off) | 0.2 (Off) | Off | Off | Extremely fine, Custom |
size3 and size6 set Calibrate for = Fluid dynamics; the others do not print a calibration.
A.3 Mesh operations¶
| Node | Type | Selection |
|---|---|---|
ftri1 Free Triangular (not pore) |
Free Triangular | Domains 1, 3 (reservoir + membrane); children size1, size5, size6, size3 |
ftri2 Free Triangular (pore) |
Free Triangular | Remaining (Domain 2); child size2 |
No Boundary Layers node exists. No Distribution, Mapped, Corner Refinement, Adapt or Refine node exists. The wall is resolved purely by the 0.05 nm boundary size with growth rate 1.05. Boundary-layer parameters (number of layers, stretching factor, first-layer thickness) are therefore not applicable, not merely absent. [verified]1
