Electric vehicles continue to gain popularity as automakers reduce barriers to purchasing. Manufacturers are seeking solutions to increase range, offer lower price points, and expand the availability of charging infrastructures. These barriers are just some of the reasons consumers are slow to adopt and why OEMs are getting more serious about predicting energy savings.
Finding the optimal solution to a design challenge almost always requires a complex coupling process. CoTherm, our coupling software, allows you to plan, control, and monitor multi-physics simulations for complex transient simulations like drive cycle scenarios. In order for advanced simulations to be worth your while, it is important to be familiar with the process and prerequisites so you can set yourself up for success. As we transition from discussing the importance of coupling as a whole to the necessity of accurate inputs, we will look at the specific things you must do well in CoTherm to get successful results from advanced simulations.
Engineering teams around the world are in a constant battle to shorten the time to market while producing a product that is highly responsive to the customer. For engineering teams to reach their goals, the best solution is to simulate the product in its operating environment. By pairing a thermal code with your CFD process, you can shorten the overall simulation time and get the results you need by leveraging the strengths of each tool.
As an automotive designer, cabin comfort is the foundation of customer satisfaction and ultimately, product sales. The rising tide of battery-powered electric vehicles brought a new design challenge to automakers, pushing them to find a way to optimize the sub-systems in the vehicle while avoiding enormous draws on battery power at the same time. This problem is addressed by running transient human thermal and battery tests to optimize for HVAC and battery systems. In this blog, we will understand how an automated coupling process can provide an optimized solution while avoiding the long solve times of highly transient problems.
Coupling a thermal modeling tool with your CFD code can provide accurate simulation results, giving you beneficial thermal feedback for your project. Over the past few years, the most effective process to implement these results has moved from writing custom scripts to coupling using an automated coupling program as the methods have become more robust.
