# Global Line Load \[FEA]

Global line loads apply distributed forces and moments along a polyline path defined by a set of points. The load is distributed to elements within the specified FE group that intersect the load path. This is useful for applying lane loads, barrier weights, or other distributed loads along a defined path without referencing individual elements.

## Line Load

**Load Case:** The analysis case (load case) to which this line load belongs.

**Group:** The FE group containing the elements to which the load will be distributed. The load is applied to elements within this group that intersect the defined polyline path.

**Points:** Defines the polyline path along which the distributed load is applied. Points are defined as X, Y, Z coordinates. Right-click this cell for actions: *Edit Points...* opens a point editor for manual coordinate entry; *Select Polyline (3D)...* launches an interactive 3D picker that lets you click on element edges to define the polyline path directly in the model view.

**Fx:** Distributed force intensity in the global X direction (force per unit length along the path).

**Fy:** Distributed force intensity in the global Y direction (force per unit length along the path).

**Fz:** Distributed force intensity in the global Z direction (force per unit length along the path). Use negative values for downward loads.

**Mx:** Distributed moment intensity about the global X axis (moment per unit length along the path).

**My:** Distributed moment intensity about the global Y axis (moment per unit length along the path).

**Mz:** Distributed moment intensity about the global Z axis (moment per unit length along the path).

**Convert to Node Load:** When set to Yes, the load is converted to equivalent nodal forces before analysis. This can improve performance for large models.

**Coordinate System:** The coordinate system in which the force and moment components are defined. Select Local to define forces relative to the line path direction, or Global for forces in the global XYZ directions.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.openbrim.org/templates/openbrimfea/loads-fea/static-loads-fea/global-line-load-fea.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
