Features

Dedicated for HVAC

This building HVAC simulation analysis software offers the best value for money by focusing on what truly matters — accurate problem solving. It eliminates unnecessary, underutilized features often found in expensive general-purpose CFD tools, providing only the essential capabilities needed for HVAC simulation and comfort analysis. Engineers get powerful, targeted performance for airflow, temperature, and comfort evaluation without paying for functions they don’t use.

The HVAC Simulation software provides detailed and comprehensive analysis results, covering all key comfort and airflow parameters — including velocity distribution, temperature field, Draft Rate (DR), Predicted Mean Vote (PMV), and Predicted Percentage of Dissatisfied (PPD). These outputs allow engineers to evaluate both ventilation effectiveness and occupant comfort in a single simulation, offering clear visual maps and quantitative data to support optimal HVAC design decisions.

Automated Computation

Detailed & Comprehesive results

Designed specifically to make building HVAC airflow and comfort simulation easier and more accurate. It allows users to define boundary conditions, diffuser settings, and occupant zones quickly using templates based on industry best practices, eliminating the complexity of general-purpose CFD tools. This streamlined approach ensures reliable results for air distribution, temperature uniformity, and thermal comfort analysis with minimal setup time.

Intuitive Pre-processing

One of the most valuable features of tensorHVAC-Pro is its high compatibility with existing ACE (Architecture, Construction, and Engineering) software. Unlike traditional CFD tools that require extensive geometry cleanup or manual preparation of negative fluid domains, tensorHVAC-Pro streamlines the entire process. Users can directly import STL geometry from their existing design software — such as Revit, SolidWorks, or Rhino — and start the simulation almost instantly.

Automatic Meshing

You don’t need to be an expert in CFD simulation to get accurate and reliable results. TensorHVAC-Pro is designed to assist users by automatically suggesting meshing strategies that follow established best practices in HVAC simulations. Whether you are analyzing air distribution, ventilation efficiency, or thermal comfort, the tool intelligently recommends mesh settings—such as cell size, refinement zones, and boundary layer configurations—that align with professional flow and thermal HVAC simulation software standards. This ensures that even users with limited CFD experience can achieve high-quality simulations efficiently, without the need for deep technical knowledge of meshing theory or solver setup.

Intuitive Physics Inputs

With TensorHVAC-Pro, you can easily define key parameters such as velocity, temperature, and other physical properties through an intuitive interface equipped with built-in unit converters. This means you don’t have to worry about complex unit conversions or remembering exact numerical ranges—simply input the values in the units you’re most familiar with, and the software automatically handles the rest. This intuitive approach streamlines the setup process, allowing users to focus more on analyzing HVAC performance rather than dealing with tedious preprocessing tasks.

Comprehensive Results

Beyond just visualizing airflow velocity and temperature distributions, TensorHVAC-Pro also provides insights into key thermal comfort parameters based on industry best practices. These include indicators such as Predicted Mean Vote (PMV), Predicted Percentage of Dissatisfied (PPD), and local discomfort factors related to draft, vertical temperature differences, and radiant asymmetry. By integrating these comfort metrics directly into the flow and thermal HVAC simulation software results, users can assess not only the system’s performance but also the actual comfort level experienced by occupants. This feature allows engineers and designers to make informed decisions to optimize HVAC designs for both energy efficiency and human comfort — all within a single, user-friendly environment.

Various Scenarios

With TensorHVAC-Pro, you can explore a wide range of flow and thermal HVAC simulation software scenarios tailored to different HVAC applications. These include indoor comfort analysis, where airflow distribution and temperature gradients are evaluated to ensure occupant well-being; cooling and heating performance studies, which help optimize system efficiency; and natural or forced ventilation scenarios, useful for understanding air renewal and pollutant dispersion in enclosed spaces. The software also supports external flow simulations, such as wind impact on building facades or outdoor air intake performance. Beyond these, TensorHVAC-Pro enables users to simulate countless other conditions—making it a versatile and comprehensive tool for engineers, architects, and HVAC professionals seeking data-driven insights into environmental performance and thermal management.

Super Intuitive GUI

tensorHVAC-Pro is designed for non-simulation enigneering user, you just have to focus on your building HVAC simulation analysis, no need to understand complicated computation terms.

What is CFD Software?

Computational Fluid Dynamics (CFD) software is a digital simulation tool used to analyze how fluids — such as air or water — move and interact with surfaces. It solves the fundamental equations of fluid flow and heat transfer (known as the Navier–Stokes equations) to predict velocity, pressure, temperature, and other related properties within a system. Engineers use CFD software to visualize airflow, optimize designs, and improve efficiency without the need for costly physical testing. In HVAC applications, CFD helps model how air circulates inside rooms or ducts, ensuring proper ventilation, thermal comfort, and energy efficiency before systems are built.
