The app supports one-dimensional, two-dimensional, and three-dimensional geometries, as well as several common fin configurations, using analytical solution methods.
Features
• Solve heat-transfer problems in 1D, 2D, and 3D solids
• Analyze fin geometries using analytical fin theory
• Support for steady-state and transient (unsteady) heat conduction
• Results shown as high-quality plots and copyable tables
• Designed for engineering students, researchers, and professionals

Supported Boundary Conditions
The app supports three standard boundary-condition types commonly used in heat-transfer analysis:
• Type 1 (Dirichlet): specified temperature
• Type 2 (Neumann): insulated or specified heat-flux boundary
• Type 3 (Robin / convection): convection boundary with heat-transfer coefficient
Solution Methods
Fin problems are solved using standard analytical fin theory under the assumptions defined for each model.
The other problems are solved analytically using separation of variables (eigenfunction and Fourier-series expansions), consistent with the specified boundary conditions.
Because the solutions are analytical, the number of nodes affects only the plotting resolution and does not influence the accuracy of results, unlike numerical methods.
Results and Visualization
• Temperature distributions are displayed as 2D and 3D plots
• Numerical results are available in copyable tables for reporting and further analysis
Disclaimer
Results are provided for educational and engineering support purposes. For critical designs or safety-related decisions, always verify results independently and ensure that assumptions and boundary conditions match the real system.
