Altair Inspire vs. ETAP PS

This software is incredibly intuitive and really does provide a great finished product. The software runs relatively quickly and will usually throw an error right away, which is a nice feature. I didn't use the geometry editing parts of the software, but it looks promising to be able to edit files directly in the program.

ETAP is highly recommended for evaluating static conditions in electrical power systems, whether in high or medium complexity networks. For example, study of load flow, analysis of frequency harmonics.

On the other hand, I would not recommend ETAP for the simulation of highly complex control systems that require a dynamic analysis of the variables.

• Defining the actuators, pin joints, sliding joints is very easy.
• Defining a motion sequence is straightforward.
• The UI tends to make you follow a sequence of steps to be successful in doing a motion simulation and finite element analysis study on a design.
• The motion simulation results are automatically transferred to the FEA solver.

• Excellent facility for the design of electrical systems, since it has multiple options and configuration.
• Truly intuitive, it is easy to adapt to the user interface, so the learning curve is very fast.
• It offers a wide variety of electrical studies that can be carried out, therefore it is very versatile for multiple applications.

• I think the tools to create CAD are a bit difficult to use. Consequently, it is now easier to develop the part in other software, which is bad since we need to use more than one tool at a time.

• Perhaps the interface is somewhat confusing the first time you use the program.
• It offers a wide configuration, which can be overwhelming.
• Sometimes the program can freeze depending on the size of the electrical grid that is being simulated. This also depends on the software requirements.

ETAP PS is really easy to use. When recreating the power system to be simulated, it is easy to obtain a result close to reality due to the multiple components offered in the interface. As for the electrical studies available, they are simple to execute and require really little configuration to make them work, always offering a wide variety of options to adjust the program to the simulation of the desired condition.

When I needed clarification on how do use a feature or best way to define the constraints for a design problem, the response was quick and solved my needs.

Sometimes when the program crashes for a random reason, it is difficult to find a direct solution to the problem. I think better documentation is needed for this type of case. Still, more and more people are sharing their work on the web, making it easier to orient yourself when these issues occur.

Working Model, MathCad, Dynamic Designer, Algor, and Mathlab had poor UI's and poor ways to define actuator and motor motion profiles. The force results and vectors were not easy to input into the FEA software. SOLIDWORKS Motion does not have an excellent way to define a linear actuator or its motion profile. Altair provides a UI that guides you through defining your linear actuator or motor's motion profile quickly.

Simulink allows to analyze and simulate different variables with respect to time in an electric power system, but it is more focused on visual programming On the other hand, ETAP is better designed for static simulation of power systems, offering options and studies in a very more direct and easier to execute.

• In my personal opinion, we think that this product does not have any negative aspect that makes us feel very uncomfortable.

• Improves the reliability of the electrical system.
• Study of the system operations, allowing a better adjustment of the facilities that are in production.
• Provides results that allow you to select solutions for energy saving.
