HeatCond2D: Reimagining Thermal Analysis
For years, we observed a persistent bottleneck in the engineering world where computational thermal analysis was confined to complex, commercial desktop software. Because of steep licensing costs, these tools remained entirely out of reach for students and independent professionals. Even within large corporations, licenses were limited, forcing engineers to queue and wait for their turn just to run a simulation.
The idea for HeatCond2D came from a moment of pure curiosity at a previous workplace many years ago. We watched a colleague write a script just to analyse heat transfer in a concrete section. The output was a wall of raw numbers, but the underlying utility was fascinating. It got us thinking, what if we could take this power, couple it with visual clarity, and put it directly into the hands of every engineer? We carried this vision for years, waiting for the right moment to build a solution that was fast, accessible, and completely unchained from a desktop desk.
When we finally began developing the app, our core priority was to simplify the user interface without stripping away professional capability. We started by integrating it with our geometry creation part of our section property app, GeoProp, to ensure geometry creation was seamless.
However, bringing computational heat transfer analysis to mobile devices meant confronting immediate hardware and computational limits. To solve this, we decided to develop the heat transfer app using the two-dimensional explicit finite difference method and introduced symmetry modelling, allowing users to reduce the computational load by analysing halves or quarters of a shape without sacrificing accuracy.
Every feature we added was driven by a desire to optimise the user’s workflow. We knew from experience that manually creating meshes is tedious and time consuming, so we engineered an intelligent auto-meshing system to get users moving instantly, while still leaving the door open for manual adjustments if a specialist needed finer control.
We packed the engine with both steady-state and transient solvers, alongside standard boundary conditions, giving users the flexibility to model real world thermal scenarios right on their devices. Finally, we tackled the final roadblock of commercial software which is reporting. Instead of spending hours manually compiling data and screenshots into spreadsheets, we built an export to PDF feature to generate polished engineering reports instantly.
Ultimately, we envisioned HeatCond2D as a bridge between academic theory and rapid field deployment. For students and educators, it serves as a visual learning companion. Instead of just memorising equations, students can use the app alongside manual calculations to instantly visualise temperature distribution and see how cooling or heating modes actually work within a section. For instance, heat transfer through sections made of different materials like concrete and steel.

Figure 2: Symmetry modellingWe all know that sometimes the exposure might not be constant but time dependent. While users are given the feature to manually enter the temperature with time, we have also develop a feature to allow the users to specify the temperature profile as a function of time to save time if the temperature can be expressed as an expression.

Before diving into laborious, time consuming simulations on restrictive commercial software, engineers can use HeatCond2D to rapidly iterate through preliminary scenarios, test simulation options, and lock down design directions, for instance, a square concrete column subjected to different boundary conditions.
