Examples

Each example is a folder in the repository's examples/: a script that builds a small model, solves it and opens the result in the workbench. Clone the repository, start Docker and run one from the repository root; Install covers uv and Docker.

The quickstart project is the fourth. uvx femforge new writes it anywhere, with no clone.

  • The quickstart workbench: a disc magnet over a steel plate, revolved from its axisymmetric section into 3D, with field lines drawn through the air

    Magnet and plate

    A disc magnet pulls on a steel plate across four air gaps, solved on the axisymmetric section and shown revolved into 3D. The project uvx femforge new writes.

  • The bearing-seat workbench: the Runs list at the left, the 4 mm magnet with its shell revolved into 3D with field lines, and the run's details below

    Bearing seat

    A neodymium disc magnet holds a steel ball in a spherical seat. The pull with and without a steel shell around three magnet sizes in 2D, then the 4 mm magnet in 3D, in a workbench that lists each run as it finishes.

  • The coil-current workbench: the solenoid's section mirrored across its axis, with field lines through the plunger, the frame and the air gap

    Coil current

    A copper coil inside a steel pot frame pulls a steel plunger toward the frame's bottom plate. The coil is driven by a current density, solved at two air gaps and shown mirrored across the axis.

  • The thermal workbench: a copper puck on an FR4 board in 3D, colored by temperature from the ambient blue of the board's corners to the yellow of the puck

    Thermal

    A copper puck dissipates 1 W on a square FR4 board and still air cools every exposed face. The steady temperature in 3D, with the peak and its rise over the air.
