Category: Thermal Cooling for Electronics and Fluid Mechanics

Vendor: Siemens

Electronics cooling software from the leader in electronics thermal analysis. The powerful FloTHERM® suite of 3D computational fluid dynamics (CFD) software predicts airflow and heat transfer, in and around electronic equipment. FloTHERM delivers right-by-design products that save design time and reduce the need for physical prototyping from components and boards to complete systems and data centers.


Thermal Integrity Analysis:

  • Expedite System Model Creation with SmallPart Library
  • Robust Industry-Standard CFD Engine
  • Automated Parametric Design Optimization
  • MCAD Imports (NX, SolidWorks, STEP, IGES, Catia,…)
  • ECAD Import (Allegro, Xpedition, PADS,…)
  • Powerful Result Visualization w/Particle Flow Analysis


The FloTHERM Suite is comprised of:
FloTHERM – established over 25 years and the flagship tool for electronics cooling simulation

FloTHERM XT – a CAD enabled electronics cooling simulation tool built to be truly part of the product design process

FloTHERM PACK and FloTHERM IC – solutions for package-level model and metric creation, whilst FloTHERM PCB excels at automating PCB-level thermal design.


  • FloTHERM has more installed seats than all other electronics cooling CFD software. For over 25 years FloTHERM has supported a huge customer base, including almost all the major blue-chip electronics companies in the world. FloTHERM supports chip, package, board and system design, and even extends out to datacenters. It is designed as a vertically-specialized solution for the electronics thermal market through its innovative SmartPart technology, extensive libraries, tailored and stable solution technology, state-of-the art compact thermal modeling techniques and parametric analysis & optimization functionality. FloTHERM features advanced interfacing technologies for working with EDA data from Mentor Graphics, Cadence and Zuken and is backed by a family of ancillary solutions for PCB (FloTHERM PCB) and package modeling (FloTHERM PACK and FloTHERM IC).  See more on FloTHERM

Flotherm Testimonial


  • FloEFD is a general-purpose CFD code capable of analyzing a wide variety of fluid-flow and heat transfer phenomena across various industries and applications. It is unique in that it is available as an embedded solution for most popular MCAD systems, and thus fully integrates into mechanical design engineering workflows. For electronics applications, FloEFD’s Electronics Cooling Module offers a subset of thermal simulation capabilities tailored for mechanical design engineers who encounter electronics cooling alongside other design challenges in product development; and require some capabilities to reside inside their MCAD design environment for consistency and productivity reasons.

As part of a large engineering process, Simcenter FLOEFD can also tightly couple with FLOMASTER (the leading system level thermo-fluid simulation tool) for when more detail is needed for a given component and with other system level tools through Functional Mock-up Interface (FMI) for total system of system analysis.

  • FloTHERM® XT, like FloTHERM, has been designed from the ground up as a full-scale, vertical solution with a customized GUI and focused functionality appropriate for electronics thermal applications. Building on FloTHERM’s ethos and success, and FloEFD’s meshing and solver technology, FloTHERM XT supports the SmartPart and Library functionality that first evolved in FloTHERM, but brings a CAD-centric approach to thermal engineering through its best-in-class CAD connectivity and advanced CAD modeling capabilities. It also features advanced EDA interfacing technologies. FloTHERM XT offers seamless simulation capabilities for all stages of the mechanical design process (concept, architecture, detailed optimization & verification). It enables a true integration between EDA and MCAD design flows, through
    concurrent engineering simulation, and extends our reach in addressing the needs of a rapidly evolving electronics thermal sector. See more on FloTHERM XT…

Flotherm XT testimonial


  • FloTHERM® PACK / IC is a unique, web-based solution that easily generates reliable, accurate thermal models of IC components, test boards, standard test harnesses and other associated parts 20 times faster than conventional approaches. Inbuilt design intelligence will make realistic assumptions about unknown package parameters.

Generate state-of-the-art detailed and compact models of your IC components. Share and archive thermal libraries within your organization using our unique workgroup features. Once defined, detailed 3D thermal IC package models, 2-Resistor or DELPHI compact thermal models can be downloaded in standard .pdml format for use in FloTHERM®, FloTHERM® XT or FloTHERM® PCB.

With more than 30 IC package families supported, users can parametrically specify a package design with only a few clicks. See more on FloTHERM PACK..

FlothermPack testimonial
