The Student Version is distributed directly by Powersim Inc. It is no longer a separate "demo" file; rather, the student version is activated via a specific license key within the standard installation package.
Filter the Marketplace by "Student Edition Bundle," locate Altair PSIM , and download the installer. Download Psim Student Version
SIMVIEW will launch automatically. Select the voltage across your load resistor to view the stepped-down DC output waveform.
A: Altair has discontinued the 32-bit version of PSIM. Always download the 64-bit installer for best performance and compatibility.
Leo stared at the dark screen. The deadline was met. The simulation was perfect. But the only thing he could hear was the low, humming ghost of a waveform he had unknowingly sold for the price of a free download. | Feature / Capability | Student / Demo
The is a fully functional version of the software provided at no cost to students and faculty worldwide. Since Altair's acquisition of PSIM, the student program has been streamlined and expanded to offer nearly limitless access to the software.
He entered the netlist manually. 67 components. The “Advanced Unlock” menu ignored the limit. He ran the simulation. On the XY plot, not a butterfly emerged, but a shimmering, fractal lightning bolt—a shape no textbook had ever recorded. A new waveform.
Ideal for simulating heavy power electronic circuits quickly. | No practical limit on waveform points
