Thermal center

Calculation Tool Functionality

This tool offers a comprehensive analysis of a suspended 3D rigid body subjected to thermal expansionforces. The tool accepts various inputs, including:

Spring direction vectors, connection points, and spring stiffness.
Torque axis direction vectors and torque stiffness.
CTE and delta temperatures for absolute reference.

For user convenience, the inputs section provides the option to plot, which can be easily accessed using push buttons to expand the relevant sections. To prevent misinterpretation it is adviced to use the SI unit system. Direction vectors are automatically normalized in the background.
By utilizing this tool, users can gain valuable insights into the behavior of suspended 3D rigid bodies and conduct in-depth analyses efficiently.

Mind that error handling is limited. Make sure all input are numerical values. Tooling is not yet overly benchmarked so usage at own risk.
