Getting Started

Get Access to Grøft Design

Grøft Design is a subscription-based web application. To obtain a license contact us.

If your organization have licenses to Grøft Design, the organization’s administrator can assign a license to you. Please note that the license is personal.

Start Your First Project

Visit the project overview page to create a new project. Simply fill in the required project details, and you’ll be ready to start.

Note that you can also manage the componets in Grøft Design and create new cables for your project if needed.

Create a Trench Segment

Projects are composed of various trench segments, each representing a 2D cross-section of the trench. By entering the length of the trench segment, you can obtain an accurate estimate of masses and materials within it.

Design Your Trench Section

Upon creating the trench segment, you will enter the section designer. Here, you can add cables, pipes, concrete duct banks and other materials. You can also experiment with different conditions for the surrounding masses.

Add a cable and apply current. You can pick one of your favorite cables or choose among an extensive cable library by using the search button.

Run simulations to check temperature and magnetic field.

Often the thermal resistivtity in the conductor zone will be worse than 1 mK/W, for example if you have dry out. In Grøft Design you can quickly run simulations of different soil conditions.

If you rerun the simulation the temperature increase is significant. To bring the temperature down, go up in cable size, lower the current or change the laying conditions. All can easily be done in Grøft Design.

Ground Wire

Take note of the ground wire in the trench segment. If it’s unnecessary, simply remove it by selecting the wire in the designer or items menu and clicking the delete button.

Collaborate and Share Projects

For collaboration, manage project access on the project permissions page. Share projects within the organization or with external users, granting either read-only or full access.

Export Report

Once satisfied with the project, export results for a single trench segment or multiple segments. Customize the exported values to include specific details.
