Does Ansys use CPU or GPU?

A CPU, or Central Processing Unit, is the primary component of a computer responsible for executing instructions of a computer program. It is often referred to as the "brain" of the computer. It processes the data and performs calculations that make software applications and the overall system function. Modern CPUs often come with multiple cores to handle parallel processing, enhancing overall computing performance.

While graphics processing units (GPUs) have been around for many years, only recently have they begun to be used to perform general purpose computations. GPUs offer a highly parallel design which often includes hundreds of compute units and have their own dedicated physical memory. Certain high-end graphics cards, the ones with the most amount of compute units and memory, can be used to accelerate the computations performed during a simulation.

Ansys can use both CPU and GPU for simulations.

What is Python and is it used in Ansys?

Python can be used in almost all of the Ansys software. It's a programming language which can be used to write scripts that can be used to automise tasks. When you have to perform multiple simulations it can come in handy to use a Python script so that you only need one push on the button. 

Python can be used as an interface in the Ansys software, but also as a standalone. For example: you can use Data Processing Framework (DPF) for postprocessing of results, like putting your results in a .csv. 

More information on using Python can be found in the Workbench Scripting Guide in the Ansys Help portal. 

What is Ansys Workbench?

Workbench is a simulation tool which allow you to connect multiple types of simulation like CFD, Maxwell, HFSS and Mechanical. This gives you the opportunity to configure your process and to optimise your simulation via parametric management.

What are the different types of simulation?

Ansys offers a broad portfolio of simulation software in the fields of Structures (FEA), Fluids (CFD), Electromagnetics and Optics. The different physics can be connected through the Ansys Workbench Interface, which allows you to perform multiphysics simulations as well. 

You can visit our different Ansys Solutions pages for more information on the different types of simulations Ansys has to offer.

How does simulation work?

Your simulation process starts with a technical design, usually a 3D CAD format. The geometry of the design is split into cells or elements, depending on the physics of your simulation.

When the design is ready, you can create conditions that tell the software how the design will be used in real lief. Based on these conditions, Ansys applies the 'laws of nature’ to simulate the reaction of your design. After this, the analist can use post-processing and make design decission based on the outcome of the simulation.

What is Ansys APDL?

APDL is short for Ansys Parametric Design Language. It's a powerful programming language which is used to control the Mechanical solver in the Ansys software.

John Swanson, the founder of Ansys, developed the APDL in the ‘80s to provide users the ability to build parametric models. Through APDL scripts (macros), the entire workflow of Ansys analyses can be automated. The code provides access to powerful vector and matrix operations. 

Today, the APDL is still used, primarily to optimize settings for the Mechanical Solver when they are not available in the Ansys Workbench. It gives users the possibility to customize their models and perform complex actions.

What is Ansys HFSS?

Ansys HFSS (High-Frequency Structure Simulator) is a 3D electromagnetic (EM) simulation software which primarily uses a Finite Element Method (FEM) solver along with other state-of-art solver technologies to simulate high-frequency electronic products such as antennas, Radar systems, satellites and other EM devices and systems. It is software which can address diverse electromagnetic problems both in detail and scale. Its reliable automatic adaptive mesh refinement lets the user focus on the design instead of spending time determining and creating the best mesh.

ANSYS HFSS allows system and circuit designers to simulate EM issues such as losses due to attenuation, coupling, radiation and reflection. Simulating a system’s High Frequency behavior with high accuracy reduces the resources and time spent on final testing and verification of the system, as well as reducing the need for manufacturing multiple prototypes, saving both time and money in the product development process.

What is Ansys?

Ansys is the worldwide market leader for Finite Element Analysis.
The software Ansys offers helps engineers to increase the insights in their products behaviour with the help of simulations. Such as electromagnetic analysis, stiffness analysis and others.

Which Ansys version is the best one to use?

The latest version.
Every year Ansys comes with two updates. A major release at the beginning of the year and a minor one after the summer. Every update comes with bug fixes, additional functionalities and additional optimizations for exiting processes. Make sure to install the latest version so that you’re up to date and have the best results.

You can recognize versions by their name, year+R+update number. For example: 2024R1 or 2024R2.
