Revolutionize Your Thermal Design

Improve electronics thermal management for reliability with fast, accurate electronics cooling CFD simulation from initial pre-CAD exploration to final verification.

Simcenter Flotherm is a powerful thermal simulation software, designed for engineers who work in the electronics industry. This software simulates the heat transfer and flow characteristics for a variety of different electronic systems. Simcenter Flotherm allows engineers to evaluate and optimize the design of electronic systems before they are built, reducing development costs and time-to-market.

Simcenter Flotherm uses a combination of numerical solvers and simulation techniques to simulate heat flow and temperature distribution. The software’s precise modeling algorithms enable users to input detailed information about the materials, geometry, and operating conditions of electronic systems. Simcenter Flotherm has a user-friendly interface that allows engineers to easily set up, run, and analyze thermal simulations. The software can handle complex geometries, allowing engineers to model a wide range of electronic systems, including printed circuit boards, power electronics, and server racks. The software also integrates with other software tools, such as computer-aided design (CAD) and computational fluid dynamics (CFD) software. This integration enables engineers to import 3D models of their electronic systems into Simcenter Flotherm, reducing the time and effort required for manual input of geometry data.

Simcenter Flotherm offers a range of simulation capabilities, including steady-state, transient, and conjugate heat transfer. Steady-state simulations provide a quick estimate of the thermal performance of an electronic system under steady-state conditions. Transient simulations simulate the dynamic behavior of the system during start-up, shut-down, and variable operating conditions. Conjugate heat transfer simulations model the interaction between fluid flow and heat transfer through solids. Simcenter Flotherm also provides insights into convection, conduction, and radiation heat transfer mechanisms within electronic systems. The software allows engineers to evaluate the impact of different materials, air flow rates, and boundary conditions on the thermal performance of electronic systems.

In summary, Simcenter Flotherm is a powerful thermal simulation software that enables engineers to evaluate and optimize the thermal design of electronic systems. With features that allow for complex geometries and simulation capabilities that include steady-state, transient, and conjugate heat transfer, Simcenter Flotherm gives engineers the tools necessary to create high-quality electronic designs that meet the needs of their customers.

Transient thermal analysis

Simcenter Flotherm supports accurate transient analysis for electronics devices and products. It is able to model transient events at even sub microsecond timescales. You can model a variety of different transient behaviors such as time dependent power dissipation in components and transient thermostatic control modeling where model input is varied as a function of monitored temperature. These capabilities support modeling of power cycles for power electronics applications, consumer device operating power mode transitions, fan control cooling and to evaluate power derating and thermal mitigation strategies.

Robust meshing

Leverage the Simcenter Flotherm instantaneous and reliable gridding that is easy to use so you focus on thermal design. The robust structured-Cartesian method is stable and numerically efficient for meshing of typical electronics. It is further tailored for fast grid generation and minimized solution time by localized grid controls for finer resolution where needed. The value in SmartPart based, or object associated, grid generation is that it automatically updates instantly, eliminating the need for full re-gridding when geometry is changed for orientation or position over successive studies.

BCI-ROM technology

Boundary Condition Independent Reduced Order Model (BCI-ROM) technology offers advantages for fast transient thermal analysis of electronics orders of magnitude faster than full 3D CFD while preserving accuracy. Simcenter Flotherm has the capability to extract a BCI-ROM based on a conduction analysis which maintains predictive accuracy but solves up to 40,000+ times faster in demonstrated cases. The “boundary condition independent” aspect of reduced order models is extremely valuable, as this enables BCI-ROMs to be used in any thermal environment, while maintaining accuracy. BCI-ROMs can be exported in several formats: as a matrix to be solved by tools such as Mathworks Matlab Simulink, in VHDL-AMS format for use in circuit simulation tools like Siemens EDA PartQuest and Xpedition AMS to support electrothermal analysis, or in FMU (functional mockup unit) format for use in system thermal modeling in 1D tools such as Simcenter Amesim and Simcenter Flomaster that support FMI capabilities.
