  • Direct Simulation Monte Carlo (DSMC) is a probabilistic simulation method developed for calculating fluid flow in a high vacuum system. General environmental fluid flow simulation uses Navier-Stokes equations(based on continuum assumption), but in case of rarefied gas system, it's hard to apply that. In case of the fluid condition that satisfy the continuum assumption, the molecules have very short mean free path. So, the momentum exchange due to intermolecular collision can be expressed as a viscosity coefficient. But in a high vacuum system, the gas density is lowered and the molecular mean free path becomes longer which causes the continuum effect to disappear. Therefore, under these condition, the system should apply DSMC, not to use Navier-Stokes equation.
    Even a high vacuum system (10-4 - 10-6 [Pa]) in the precision industry, so many molecular are there. Moreover, even a high vacuum system, the local pressure can increase and the number of molecules will increase accordingly. To solve this problem, DSMC uses a representative particle method.
    The industries using deposition and sputter processor which produce precision product such as display and semiconductor use various vacuum devices. samadii/sciv analyzes and predicts the flow characteristics, pressure, temperature, impact,deposition thickness, etc. of these devices. Also. It can be used for analyze the fluid flow around space shuttle and help to design that shape.

  • Electromagnetic phenomena are applied in many industries such as wireless communication, radar, motor, semiconductor and display. These electronic devices make human life convenient. The devices have been required to be smaller and faster. In order to satisfy the demand, analysis of electromagnetic field is essential. samadii/em is an engineering software that analyzes the electromagnetic field in three dimensional space using the Maxwell equation, a governing equation that can comprehensively represent these electromagnetic phenomena.
    Using samadii/em, it is possible to design and analyze electromagnetic devices in various fields such as motors, transformers, sensors and switches. It can analyze problems in electrostatic fields, transient electromagnetic fields, AC electromagnetic fields, and electromagnetic fields and supports interpretation in industrial fields such as power, electricity, electronics, semiconductor, electric motors, wireless devices and consumer electronics.

  • Plasma is the fourth state of a solid-liquid-gas material, meaning an ionized gas composed of a large number of free electrons, ions, and neutral atoms or molecules. The plasma is used in the dry etching and deposition processes in manufacturing semiconductors, displays and PCBs. In particular, these processes are one of the key technologies for creating micro and nanoscale highly integrated circuits. To simulate this plasma process ,in past, modeled electrical fluid flow and interpreted based on finite volume or element. However, the basic element that forms the plasma is the particles. By calculating the collision of these particles, the plasma reaction can be simulated more accurately. samadii/plasma offer the solution of the plasma process using the high speed electric field module of samadii/em. And cosimulate the particles of plasma using the samaii/sciv with GPU computing.
    The samadii/plasma makes it possible to visualize the plasma process through ion and electron particle behavior. It also helps in plasma process design by providing process uniformity, process chamber plasma density, temperature, and flow rate.
    samadii/plasma can utilize surface treatment processes (etching, ion implantation, sputtering, etc.) analysis using plasma in high vacuum chambers in the semiconductor display PCB manufacturing industry. It can also be used in the environmental and energy industries to interpret processes involving charged particles in an electromagnetic field.

  • DEM used in samadii/dem called Discrete Element Method or Distinct Element Method and is a numerical method for calculating how many particles collide and move. The basic assumption of this method is that the object are composed of discrete particles and that each particle can have different shape and characteristics. It is and effective way to simulate the behavior of mixing and grinding of granular discontinuous materials such as sugar or protein crystals, bulk materials(such as grains) of storage silos, granular materials (such as sand), powder materials (such as toners), and agglomerated rocks.
    samadii/dem uses the Lagrangian method to determine the movement of particles using 6-DOF kinematic equations and to considering all forces of individual particles. It uses the explicit method to calculate the individual particle position and velocity at the next time step. Together with gravity and the collision force between particles, it can also consider drag, buoyancy, magnetic force, Coulomb force, electrostatic force, Van der Waals force, and adhesion.
    samadii/dem is designed to reflect most of the physical phenomena in the analysis, from small particles that should be considered for Brownian motion to very large particles such as one. It considers basic contact force and gravity as well as frictional force, electromagnetic force, Coulomb force, adhesion force, buoyancy and drag force, Van der Waals force, Brownian motion and heat effect.
    samadii / dem can be used for the behavior, mixing performance and impact of solid particles of various sizes and shapes used in the industrial field (nanoparticles, viruses, print toners, chemical by-products of various chemical processes, grinding processes, sand, gravel, ore, etc.), and it's possible to predict the external force and lifespan of the structure. Applicable industries include agriculture and food, chemicals, civil engineering, oil and gas, mining, mineral processing, pharmaceuticals, and powder metallurgy.
