Scope and limits
What Elementarium models, solves and checks today, and what it does not — on one page, before you commit a job to it.

This page lists what is in the current release and what is not, so you can tell in five minutes whether a job fits. Each line links to the page that explains it. When something here changes, the release notes say so.
Model
| In | Not in this release |
|---|---|
| Bars, 2 nodes, axial only | Cables, and tension-only or compression-only members |
| Beams, 2 nodes, 6 DoF per node, shear deformation through the shear areas | Warping torsion (no seventh DoF); tapered members need subdividing |
| Four-node shells for slabs, walls, cores and curved surfaces, all-quad mesh | Triangles and solid elements |
| Springs, releases, partial rotational fixity, rigid arms, eccentric beams | Compression-only or tension-only supports, gaps and contact |
| Line supports on a Winkler bed along a member or a slab edge | A bed under the face of a raft |
| 2D Frame, 2D Truss, 3D and general model types | |
| IFC, SAF and DXF import |
Analysis
| In | Not in this release |
|---|---|
| Linear static, every case and combination | Material nonlinearity: yielding, cracking, creep |
| Modal, with participating mass and a Sturm check | Response spectrum and time-history analysis |
| Linear buckling, per load state | Lateral-torsional buckling in the analysis: a beam has no warping DoF, so LTB is left to the design check |
| Second-order, P-Δ and P-δ with EN 1993-1-1 §5.3 imperfections | Large-displacement analysis |
Loads and combinations
| In | Not in this release |
|---|---|
| EN 1990 STR/GEO and SLS combinations, 6.10 or 6.10a/b, favourable permanent variants | The EQU set, accidental 6.11 and EN 1998 seismic combinations — write those by hand |
| ASCE 7-22 LRFD and ASD, seismic with a single , and service combinations | |
| Wind and snow generated to EN 1991-1-4 and EN 1991-1-3 | ASCE 7 wind and snow generators |
| Temperature, prescribed displacements, load panels, masses |
Design checks
| In | Not in this release |
|---|---|
| Steel to EN 1993-1-1 §6.2 and §6.3, Class 4 and web shear buckling to EN 1993-1-5 | Annex A interaction factors; load height in ; mono-symmetric torsional buckling; reduction for thickness (enter it in the material) |
| Steel to AISC 360 Chapters D to H, LRFD or ASD | E5 single angles, E6 built-up members, F9/F10 tees and angles |
| Serviceability: member deflection, drift, floor-frequency screen | Slab deflection checks (read the contour), floor acceleration, crack widths |
| Concrete, timber strength, masonry and aluminium design | |
| Connections, base plates, foundations, fatigue, fire, cold-formed sections to EN 1993-1-3 | |
| Section cuts and design strips through slabs |
Size
The free plan solves up to 500 degrees of freedom, a student account 5,000, and Pro has no cap; see Plans & limits. Past the plan, the ceiling is the memory the browser can give the solver, which depends on the device; see System requirements. For scale: the 18,654-DoF road overpass example solves in about 2 s on a 16-thread desktop.
