This is the Analog Input block (Embedded→STM32→ADC→Analog Input). The docs says it output between 0 and 1, this doesn't seem to be the case I tried reading a sine signal (0 to 3 ) using the simulated analog channel block. The output of the Analog input block also outputs sine (0 - 3). Why is the block outputting 0 - 3 and…
Goodmorning, I'm working with Altair Flux 2024 with topology optimizations. I performed an optimization of the rotor of a SPMSM and I would like to perform another topology optimization on the previous design result. In particoular I would like to use the same densities of the design produced by the first optimization as…
Hi all, Does anyone have any training materials or tutorials on running DOE and optimization in Inspire Cast that you could share with me? Best regards,
Hi all, I’ve been trying to analyze the particle collision number in EDEM 2025.1, but I’m encountering an issue where the collision number results remain zero.
