Flow Simulation

The volume of fluid method (VOF) used to simulate flows with a freely moving interface between two immiscible fluids is enhanced in SOLIDWORKS Flow Simulation 2021, enabling you to include rotating regions and solve mixing simulations more accurately.

Fluid Flow Simulation

SOLIDWORKS Flow Simulation allows you to analyze your models in their environment! See how gaseous and liquid fluids interact with your design and optimize them for peak performance. Study pressure drop, manage thermal factors, tune velocities and more!

Thermal Flow Simulation

Enables analysis of conjugate heat transfer (thermal conduction in solids, convection between fluid and solid, and radiation) using computational fluid dynamics (CFD).

Advanced Radiation Simulation

Analyze absorption of radiation in solid bodies and definition of the radiation spectrum for a more accurate radiation simulation.

Design Comparison Studies

Enables you to evaluate multiple scenarios for your design—you specify discrete values for each variable and use sensors as constraints.


SOLIDWORKS Flow Simulation provides some of the most stunning visual options for analyzing your data. Animate flow trajectories, pinpoint areas of interest with cut plots and track trends with surface plots.

Concurrent Engineering

The key to getting a great design to market, is making smart decisions as early in the process as possible. SOLIDWORKS Flow Simulation makes that possible in the same way it does with its entire Simulation suite. Analysis can start as soon as an idea forms and can impact every decision throughout the rest of the design phase!

Time-Based Studies

SOLIDWORKS Flow Simulation can go beyond steady state solutions! Use Flow to explore real-time phenomena that impact your designs. Use transient studies to investigate a range of situations including trailing vortices and active heating or cooling scenarios.

Flow with HVAC Module

The HVAC module offers industry-specific tools and methodologies offering unrivaled user-friendliness, control and efficiency. The HVAC module allows designers to monitor and optimize the regulation of airflow and temperature in work and living environments.

Thermal Comfort Parameters

Comfort is subjective. But that doesn’t mean you can’t design for it. Optimize the percentage of comfortable inhabitants in your space by using Flow Simulation. This capability allows you analyze the way your space is brought to temperature and minimize the impact on the room’s occupants.
