Design checks<br>Check members against the design code and see the governing case, the utilisation ratio and the clause behind it.

Output reports<br>Hand a reviewer one document: inputs, model, results and checks, laid out the way a calc package should be.

Loads & combinations<br>Build load cases, generate combinations from the code of your choice, and find the case that governs.

Results you can read<br>Diagrams, contours, envelopes and tables — read the picture or read the number, whichever settles the argument.

Sections & materials<br>Assign sections and materials once, reuse them across the model, and change them without rebuilding anything.

On the roadmap

Nonlinear analysisNonlinear static, P-Delta and large displacement — the next big one on the list.<br>Parametric modelingDrive geometry from dimensions, then rebuild the whole model when one changes.<br>Scripting APIAutomate parametric studies and pipe results into your own tooling.<br>More design codesFurther material codes and national annexes, driven by what users ask for.

Collaboration & sync<br>Solves locally. Syncs everywhere.<br>Compute happens on your hardware, but your work does not live and die there. Elementarium keeps a versioned copy of every project in the cloud and lets your team into the same model at the same time — and it still works on a train with no signal. When you reconnect, everyone's edits merge without a conflict file in sight.<br>Real-time multiplayerEveryone sees the same model as it changes — no check-outs, no master file.<br>Conflict-free mergesTwo engineers, one model, no connection. Both sets of edits survive the reconnect.<br>Versioned historyEvery project is snapshotted as you work, so last Tuesday is always one click away.<br>Backed up by defaultYour laptop is not the backup. Sign in anywhere and your projects are there.

The workflow<br>Concept to calc package, in one tab<br>The whole loop lives in the browser — no exporting, no re-importing, no version chaos between tools.

01<br>Model<br>Lay out members on a grid, then assign sections, materials and supports in a keyboard-first modeler.

02<br>Load<br>Apply your load cases and let Elementarium build the code combinations for you — then envelope the set.

03<br>Solve<br>Hit solve and watch it finish. Results stream into the viewport as fast as your own CPU can produce them.

04<br>Check & report<br>Check members against the design code, then export a fully traceable calculation report.

Why the browser<br>Local compute, without the desktop baggage<br>You get the speed of a solver on your own hardware and the convenience of something that lives at a URL.
