Altair SimSolid: Accelerating Product Development with Fast and Accurate Structural Analysis


In today's competitive market, engineers and designers face numerous challenges when developing new products. One of the most significant hurdles is the time-consuming process of performing finite element analysis (FEA) on complex assemblies. Traditional FEA software often requires extensive geometry simplification and meshing, leading to longer design iteration cycles and delayed time to market. Altair SimSolid, a revolutionary structural analysis software, addresses these pain points by providing fast and accurate simulations, enabling engineers to optimize designs efficiently and cost-effectively.

Streamlining FEA for Complex Assemblies

Fast FEA for Complex Assemblies with Altair SimSolid

Altair SimSolid's unique technology eliminates the need for geometry simplification and meshing, allowing users to run simulations directly on fully-featured CAD assemblies. This capability significantly reduces the time and effort required for analysis, enabling engineers to focus on design optimization rather than time-consuming preprocessing tasks. With SimSolid, engineers can import CAD models from various supported file formats, such as STEP, IGES, and Parasolid, and perform accurate simulations without the need for manual geometry cleanup or simplification.

Reducing Design Iteration Time Through Rapid FEA in Altair SimSolid

One of the most significant challenges engineers face during the product development process is the lengthy design iteration cycle. Traditional FEA software often requires hours or even days to set up and run simulations, limiting the number of design alternatives that can be explored. With SimSolid, engineers can perform multiple iterations of their most complex models and explore design alternatives at unprecedented speeds. According to a case study by Altair, a leading automotive manufacturer reduced their design iteration time by 75% using SimSolid, compared to traditional FEA methods. This rapid simulation capability allows users to make informed design decisions early in the development process, ultimately shortening the overall product development timeline.

Comprehensive Simulation Capabilities

Simulating Linear Static, Modal, and Thermal Properties with SimSolid

SimSolid offers a wide range of simulation capabilities, including linear static analysis, modal analysis, and thermal analysis. These functionalities enable engineers to calculate stresses, strains, and displacements, predict vibration behavior, and optimize thermal performance. By providing a comprehensive set of simulation tools, SimSolid empowers users to gain valuable insights into product performance and make data-driven design decisions.

For example, a consumer electronics company used SimSolid to optimize the design of a smartphone case. By performing linear static analysis, they identified areas of high stress concentration and redesigned the case to improve its structural integrity. Additionally, the company used SimSolid's thermal analysis capabilities to ensure that the device's internal components remained within acceptable temperature ranges, preventing potential overheating issues.

Simulating Bolted Connections for Robust Product Development with SimSolid

One of the key features of SimSolid is its ability to analyze various connection types, such as bolts, welds, rivets, and sliding contacts. This functionality is particularly important for industries like aerospace and automotive, where the integrity of bolted connections is critical for product safety and reliability. By accurately simulating the behavior of these connections, engineers can ensure that their designs meet the required performance standards and avoid potential failures.

In a recent project, an aerospace manufacturer used SimSolid to optimize the design of a wing assembly. By simulating the behavior of the bolted connections between the wing panels and the underlying structure, the company was able to identify areas where the bolts were experiencing excessive stress. Based on these insights, the engineers redesigned the connection points, resulting in a more robust and reliable wing assembly.

Design Optimization and Cost Reduction

Optimizing Designs for Weight Reduction and Performance Using SimSolid

SimSolid's integration with Altair Inspire enables users to perform topology optimization, which helps identify the optimal material distribution for a given set of design constraints. This material optimization capability leads to lighter, more efficient designs that reduce material costs and improve product performance. In a recent project, a leading aerospace company used SimSolid and Inspire to optimize a bracket design, resulting in a 35% weight reduction without compromising structural integrity.

Cost-Effective Design Optimization with Altair SimSolid and Material Usage Reduction

By leveraging SimSolid's rapid simulation capabilities and material optimization features, companies can significantly reduce their design costs. The software enables engineers to identify areas where material can be removed without affecting product performance, leading to reduced material usage and lower production costs. Additionally, the faster design iteration cycles achieved with SimSolid help companies bring products to market more quickly, providing a competitive edge and increasing profitability.

A real-world example of cost-effective design optimization using SimSolid can be seen in the case of a leading industrial equipment manufacturer. By using SimSolid to analyze and optimize the design of a heavy-duty gearbox housing, the company was able to reduce the overall weight of the component by 28% while maintaining its structural integrity. This weight reduction not only led to lower material costs but also improved the equipment's energy efficiency and performance.

One of the key advantages of SimSolid is its ability to perform fast and accurate simulations on complex assemblies without the need for geometry simplification or meshing. This capability sets it apart from many traditional FEA tools that require extensive preprocessing before running simulations. However, some users may prefer the added control and customization options provided by more traditional FEA software, particularly for highly specialized or niche applications.

Another factor to consider is the learning curve associated with each software package. While SimSolid is designed to be user-friendly and accessible to beginners, some users may find the interface and workflow of other FEA tools more intuitive, particularly if they have prior experience with those software packages.

Ultimately, the choice between Altair SimSolid and other FEA software will depend on the specific needs and preferences of the user or organization. It's recommended to evaluate multiple options, consider factors such as ease of use, simulation capabilities, and integration with existing design workflows, and, if possible, take advantage of free trials or demonstrations to determine the best fit for your unique requirements.
