# Retrieves the collection of Calculations

`GET` `/simulations/{simulationId}/calculations`

Operation ID: `readCalculations`

Retrieves the collection of **Calculations**. This collection is paginated.

## Path parameters

- `simulationId` (string, string, required)

## Query parameters

- `page[size]` (integer, optional) - The page size requested by the client. The default value is 20. The maximal value is 200.
- `page[number]` (integer, optional) - The page number the client requests. The first page is always page[number]=1.
- `sort` (string, optional) - Sort query parameter permits the sorting of the collection by the values of the attribute provided in the parameter: GET /calculations?sort=+attribute The type of sort: * (+) Indicates ascending order. +attribute * (-) Indicates descending order. -attribute * If no symbol is provided, any default order could be returned **If sort is not provided, the collection is returned in a default order by ID.** The name of the attribute should exists in the object. If the name does not exists, it returns **400 Bad Request**.

## Responses

- `200` - Ok
- `401` - Unauthorized
- `403` - Forbidden
- `500` - Internal Server Error
