System Requirements

Overview

FlexSim's system requirements are divided into two tiers:

Minimum: Many modern Windows PCs meet FlexSim's minimum requirements. While the minimum requirements are adequate to trial the software, they are often underpowered for common simulation modeling scenarios.
Recommended: For regular FlexSim use, your computer system should meet or exceed the recommended specifications.

Review our FlexSim Knowledge Base article Recommended System Requirements for an in-depth discussion regarding the hardware components that make the most difference when building and running your simulation models.

Minimum System Requirements

Many desktop and laptop computers produced in the last few years meet FlexSim's minimum requirements. A system that meets these minimum requirements will allow you to:

evaluate FlexSim
work through the tutorials
build and run basic simulation models

Operating System	A 64-bit edition of Windows under current Microsoft support ¹ Windows 11 (see supported versions) FlexSim is designed and tested for local use on Windows personal computer systems ².
CPU	A modern x64 Intel or AMD processor To meet minimum requirements for performance, compatibility, and vendor support (such as driver updates) we recommend a CPU produced within the last 5 years, such as: Intel 10th-Generation Core processor (Comet Lake, Ice Lake, Amber Lake) or higher AMD Zen 3 series processor (Ryzen 5000, etc.) or higher ARM processors are not supported.
RAM	16 GB RAM or more
Graphics	A GPU supporting OpenGL 3.1 or higher To meet minimum requirements for performance, compatibility, and vendor support (such as driver updates) we recommend a GPU produced within the last 5 years, such as: Nvidia GeForce RTX 20 series (desktop) or 20 series (mobile) or higher AMD Radeon RX 5000 series (desktop) or 5000M series (mobile) or higher Intel Gen 12 Graphics or higher You may need to update your graphics driver for FlexSim to work properly. See the FlexSim Knowledge Base article Graphics Compatibility - Common Problems and Solutions for more suggestions on improving graphics compatibility and performance in FlexSim.
Disk Space	3 GB free FlexSim's installer may be up to 1.2 GB in size, depending on version. After successful installation, the installer file may be deleted. After installation, FlexSim's program files may use up to 1.2 GB of disk space, depending on version. Your model files, CAD layouts, images, custom 3D shapes, data for import, exported reports, and other simulation related assets that you provide will take disk space in addition to the software's installation footprint.
Additional Software	The latest .NET Framework ³

Recommended Specifications

For building and running your own simulations, we recommend using a modern, high-end PC with components that meet or exceed the following specifications:

Operating System	The most recent version of Microsoft Windows 11.
CPU	A CPU scoring 36,000 or better in the PassMark - CPU Mark multi-thread benchmark, and 4100 or better in the single-thread benchmark, such as: Intel Core i7-13700 or higher AMD Ryzen 7 9700X or higher
RAM	32 GB RAM or more
Graphics	A GPU scoring 26,000 or better in PassMark - G3D Mark benchmark, such as: NVIDIA GeForce RTX 4070 or higher AMD Radeon RX 9070 XT or higher

Notes

Once an operating system reaches the end of its lifecycle or is no longer supported by Microsoft, FlexSim no longer actively supports that OS. Windows on ARM is not supported.
Remotely connected systems, thin-clients, virtual operating systems, virtualized GPUs, and other non-PC environments are not tested or supported. FlexSim Software requires compatible 3D hardware and driver support, which may be missing from such environments.

Systems that do not meet FlexSim's minimum requirements, including remote and other non-PC environments as described above, may successfully run FlexSim Software and meet your compatibility and performance needs. FlexSim provides no guarantees about the suitability of such environments or systems. If you choose to use FlexSim Software on a platform that does not meet FlexSim's minimum requirements, please test thoroughly and understand that FlexSim does not provide support for such unique situations.
FlexSim Software uses functionality provided by Microsoft's latest .NET framework. A compatible .NET framework is already installed on most computers, though if necessary, it can be downloaded directly from Microsoft.
