Electrode Roller Pressing is a key manufacturing step in battery electrode production, used to achieve the desired thickness, density, and surface uniformity of the coated electrode sheets. In this process, the coated electrode—typically aluminum foil for the cathode or copper foil for the anode—is passed through a pair of…
In battery manufacturing, aluminum foil is widely used as the current collector for the cathode due to its excellent electrical conductivity, corrosion resistance, and low density. During the electrode fabrication process, large sheets of coated aluminum foil are precisely cut into the required shapes through a process…
Contact modeling is a critical component of multibody dynamics simulations, especially in applications involving latch mechanisms, robotics, electric tools, and similar mechanical systems. Accurate and efficient contact handling significantly impacts the realism and stability of the simulation. Overview In multibody…
Altair Compose supports the creation of Graphical User Interfaces (GUIs) to simplify and streamline workflows that will be executed repeatedly or by someone unfamiliar with tools like Compose or other IDEs. Most tasks in Compose can be executed running scripts and updating relevant file paths and variable values, but they…

Sheet metal plays a vital role across industries - from automotive body structures and aerospace panels to heavy engineering equipment, consumer electronics casings, and household appliances. Each application demands the right balance of strength, weight, and manufacturability, making material selection a critical step in…
Introduction EV performance optimization starts with understanding vehicle behavior under key operating conditions. One of the most critical scenarios for both industry and Formula Student (FS) teams is the Wide Open Throttle (WOT) test - where the throttle is fully engaged, delivering maximum acceleration and power draw…
Introduction We will simulate the WLTP Class 3b drive cycle of 1,800sec in just 25sec of simulation time, which is x72 times faster than real time. Let's see how! The first part of this workflow is already covered here: Faster-than-Real-Time EV Drive Cycle Simulations with PSIM-trained Fit Models | Part1 The second part…
IntroductionWe will simulate the WLTP Class 3b drive cycle of 1,800sec in just 25sec of simulation time, which is x72 times faster than real time. Let's see how! Working with drive cycle simulation can be challenging—especially when attempting to include all the details of an electric powertrain. The main issue arises from…
Validation of CEM codes is essential if they are to be used in production analysis and design. The utility of CEM modeling is greatly diminished without trust that a given code produces answers sufficiently representative of physical reality. This topic was the focus of the recently published IEEE Antennas and Propagation…
