Introducing software that calculates the density, temperature, and pressure distribution of neutral particles using the DSMC method!
"RGS3D" is a module that uses the DSMC method (particle model) to analyze the flow field of rarefied gases in various vacuum devices. It excels in analyzing flow fields when the Knudsen number (Kn; a dimensionless number that evaluates the rarefaction of the flow, Kn = mean free path / representative length of the flow) exceeds the application limits of the Navier-Stokes equations, specifically for Kn > 0.01. Additionally, when Kn > 1, a fast Monte Carlo method can be selected. 【Features】 ■ Analyzes the behavior of neutral particles without charge under general rarefied gas conditions ■ Enables analysis of viscous flow regions by specifying a new collision calculation method ■ Capable of analyzing structures of arbitrary shapes and spatial mesh divisions ■ Provides accurate analysis for any mixed gas ■ When collisions with walls are dominant, a fast Monte Carlo method can be selected *For more details, please refer to the PDF document or feel free to contact us.
