# FEM Online — AI model link, format version 1

This file describes how to write a link that opens a structural model in the
FEM Online app (https://femonline.eu/app/). The model is written in the link itself as plain
text. When the user clicks it, the app checks the model and opens it; nothing
is sent to a server.

Format version: **1**. The app reads only this version. Source of this file:
https://femonline.eu/ai/fem-model-link.txt

## How to answer the user

1. Build the model from the user's description, sketch or photo.
2. Give the link as a clickable link: `https://femonline.eu/app/#ai=<statements joined by ;>`.
3. Also give the same statements in a code block, one per line. If the chat
   breaks the link, the user can paste this text into the app
   (Open → Paste AI model).
4. Briefly state the assumptions you made (supports, loads, sections).
5. For a change, write the WHOLE model again as a new link. The app opens a
   link as a new model; it does not apply differences.
6. If the app reports errors, the user will paste them back. Fix exactly those
   and write a new link.

Use only the materials and sections listed in this file. Do not invent names.

## Syntax

- The model is a list of statements `key=value`, separated by `;` (in the
  link) or by new lines (in the code block).
- The first statement is the version: `v=1`.
- A value is a list of items separated by `,`. The fields of an item are
  separated by `:`.
- The same key may appear several times; the items are added together.
- Names use `_` for spaces (`Snow_left`). Do not use `; , : = # &` in names.
- Numbers use a decimal point (`2.5`), no thousands separators.
- Ids are positive whole numbers, unique within their kind. Loads, members and
  supports refer to nodes, members, sections and load cases by these ids.

## Units and axes

- Lengths: metres (m). Section dimensions: millimetres (mm).
- Forces: kN. Distributed loads: kN/m. Moments: kNm. Angles: degrees.
- Global axes: X and Y horizontal, **Z vertical, pointing up**. Gravity acts in −Z.
  A downward load is therefore negative in z, e.g. `-5`.
- For a planar structure use the X–Z plane (Y = 0).
- Member local axes: x runs from the start node to the end node. For a
  non-vertical member, local z points downwards (towards −Z) and local y is
  the section's major axis, so an I-section bends about its strong axis under
  vertical load. `beta<degrees>` rotates the section about the member axis.
- Prefer global directions (x, y, z) for loads. Distributed loads act per
  metre of member length. A load given per horizontal metre (snow on a
  sloping rafter) must be converted: q_member = q_horizontal × cos(slope).

## Statements

| key | item | meaning |
|---|---|---|
| `v` | `1` | format version, required, first |
| `name` | `Project_name` | project name (optional) |
| `n` | `id:x:y:z` | node, coordinates in m |
| `s` | `id:section:material` | cross-section and the material it is made of |
| `m` | `id:nodeI:nodeJ:section[:flag…]` | member from node I to node J |
| `sup` | `node:restraint` | support |
| `lc` | `id:action:name[:sw]` | load case; `sw` adds self weight (`sw1.1` scales it) |
| `nl` | `case:node:fx:fy:fz[:mx:my:mz]` | load on a node, global axes |
| `q` | `case:member:dir:q1[:q2[:a:b]]` | distributed load; q2 for a trapezoid; a, b = start and end in m from node I (omit for the full length) |
| `p` | `case:member:dir:P:a` | point load P at a m from node I |
| `c` | `name:ULS\|SLS:<case>x<factor>:…` | combination, e.g. `ULS1:ULS:1x1.35:2x1.5` (case 1 × 1.35 + case 2 × 1.5) |
| `combos` | `auto` | generate EN 1990 ULS and SLS combinations from the load cases |

**Member flags** (optional, after the section):
- `hI`, `hJ` — hinge (both bending moments released) at the start / end.
- `rI.<dofs>`, `rJ.<dofs>` — release other forces, from `n vy vz t my mz`, e.g. `rJ.my`.
- `truss` (axial only), `tension` (tension only), `compression` (compression only), `rigid` (rigid link).
- `beta<degrees>` — section rotation, e.g. `beta90`.

**Supports:** `fixed` (all six restrained), `pinned` (ux, uy, uz restrained),
or the restrained directions joined by dots from `ux uy uz rx ry rz`, e.g. `uy.uz`.

**Load directions:** `x y z` global, `lx ly lz` member local.

**Actions** (`lc`): `permanent`, `imposed`, `snow`, `wind`, `ice`, `other`.
They decide the partial and ψ factors of `combos=auto`. Give each wind
direction or snow arrangement its own case; `combos=auto` never combines
two winds or two snows.

## Stability — the structure is solved in 3D

Every model is solved as a 3D frame, so it must be stable in all directions.
- A planar frame with pinned bases also needs out-of-plane restraint: use
  `ux.uy.uz.rx.rz` at the bases, or fixed bases.
- A simply supported beam: `ux.uy.uz.rx` at one end and `uy.uz` at the other.
- A planar truss: make the chords ordinary (continuous) members and only the
  diagonals and posts `truss`, keep it triangulated, and restrain rx at the
  supports. A truss made only of `truss` members is unstable out of plane
  unless every node is restrained in uy.

## Cross-sections

A section word is either a catalogue profile (see the catalogue below) or one of these forms.
Dimensions in mm.

| form | shape | materials |
|---|---|---|
| `R<b>x<h>` | solid rectangle, width b, depth h, e.g. `R120x240` | any |
| `D<d>` | solid circle, e.g. `D300` | any |
| `2R<b>x<h>g<gap>` | two rectangles side by side with a gap, e.g. `2R60x200g60` | timber |
| `MSH<h>x<b>x<t>` | cold-formed hollow box (`MSH-H…` hot finished) | steel |
| `Pipe<d>x<t>` | cold-formed tube (`Pipe-H…` hot finished) | steel |
| `L<h>x<b>x<t>` | angle | steel |
| `IW<h>x<b>x<tw>x<tf>` | welded I girder; `IW…/<b2>x<tf2>` for a different bottom flange | steel |
| `BOX<h>x<b>x<tw>x<tf>` | welded box | steel |
| `C<h>x<b>x<lip>x<t>`, `Z<h>x<b>x<lip>x<t>` | cold-formed lipped purlin | steel |
| `A<cm²>Iy<cm⁴>Iz<cm⁴>It<cm⁴>` | properties only (last resort, not design-checked) | any |

Prefer catalogue profiles: they are design-checked with their exact geometry.
Use the custom steel forms only when no catalogue profile fits.

## Checklist before answering

- The first statement is `v=1`.
- Every member's nodes and section exist; every load names an existing case, node or member.
- Every section word and material code appears in this file; steel shapes use a steel grade.
- Coordinates in m, section sizes in mm, loads in kN and kN/m; downward loads are negative z.
- The structure is supported and stable in 3D (see Stability).
- Point and partial loads lie within their member (0 ≤ a ≤ member length).
- Each load case has an action; `combos=auto` is included unless the user gave combinations.

## Not in the link

Springs, one-way supports, eccentricities, moment and temperature loads,
connections and dynamics are not part of the link. The user adds them in the
app after opening the model.

## Materials

Write the code exactly as listed (case does not matter). Values: E and G in GPa, density in kg/m³, strengths in MPa.

## Steel profile catalogue

Every profile below may be used as a section word. Write it exactly as listed, without spaces. Use only profiles from this list; prefer the European series unless the user asks for another region. All are steel and need a steel grade.
