摘要： A method for optimally simulating fluid flow around a real object by (a) defining an initial state of a simulation space having a plurality of lattices with nodes; determining a space occupation state by objects, a fluid state, and a probability distribution state of a particle for respective nodes; generating a flow effect for the respective nodes using a collision rule which is a probability distribution of the particle with respect to the velocity thereof, obtained by satisfying a condition at which a Tsallis or a Rényi-divergence between the collision rule itself and a reference collision rule provides a simulated fluid flow result; and renewing the initial state and varying the space occupation state based on the simulated fluid flow result; and (b) based on step (a) modeling fluid flow around the real object.

摘要： Improvements in a molecular-dynamic simulator provide ways to save energy during computation and reduce die area consumed on an integrated circuit. Examples of such improvements include different interaction modules for different ranges, the use of streaming along rows while multicasting along columns in an array of interaction modules, the selection of computation units based on balancing computational costs and communication costs, the use of fences in networks that connect computation units, and the use of bond calculators to carry out specialized bond calculations.

摘要： A ballastless track roadbed damage forewarning method considering uncertainty includes the following steps. Step 1: counting roadbed material parameters and precipitation; Step 2: establishing a FLAC-PFC model of a ballastless track roadbed and calibrating mesoscopic parameters of a roadbed surface layer; Step 3: generating a lognormal random field of particle contact friction coefficients and assigning it to particle contact nodes of the roadbed surface layer; Step 4: perform sampling on the precipitation and adjusting a fluid domain of the roadbed surface layer; Step 5: determining a worst spatial correlation distance in the random field; and Step 6: calculating a damage probability pf of the roadbed surface layer under the worst spatial correlation distance; outputting alarm information when pf exceeds an alarm threshold, otherwise, quitting. The method monitors and gives early warning of damage to the roadbed surface layer under dynamic loads, ensuring driving safety.

摘要： Embodiments of the present disclosure relate to a method of particle system analysis. The method includes during an analysis of behavior of particles in a particle system, applying a scalar to a position value for at least one particle of the particles. The scalar may be based on parameters for the analysis. The method may further include after applying the scalar, truncating the position values corresponding to the particles, and determining a distance between a first particle and a second particle based on the truncated position values of the first particle and the second particle. The method may further include determining a behavior of the particle system based on the distance.

摘要： Embodiments of the present disclosure relate to a method of particle system analysis. The method may include during an analysis of behavior of multiple particles in a particle system, applying a scalar value, based on one or more parameters for the analysis, to a position value for one or more particles of the multiple particles. The method may further include determining, after applying the scalar value, a distance between a first particle of the multiple particles and a second particle of the multiple particles using the position values of the first particle and the second particle and converting the distance from a first value type to a different value type using the scalar value. The method may further include determining a behavior of the particle system based on the converted distance.

摘要： A global computer aided engineering (CAE) model representing an electronic product that contains solder joints and an individual detailed solder joint model are received. The solder joint model can include a solder ball, one or more metal pads, a portion of printed circuit board, and a portion of semiconductor chip component. The global CAE model includes locations of the solder joints to be evaluated in a drop test simulation. The solder joint model is replicated at each location to create a local CAE model via a geometric relationship between the global CAE model and the local CAE model. Simulated physical behaviors of the product under a design condition are obtained in a co-simulation using the global CAE model in a first time scale and the local CAE model in a second time scale. Simulated physical behaviors are periodically synchronized based on kinematic and force constraints.

摘要： A lithography method using a multiscale simulation includes estimating a shape of a virtual resist pattern for a selected resist based on a multiscale simulation; forming a test resist pattern by performing an exposure process on a layer formed of the selected resist; determining whether an error range between the test resist pattern and the virtual resist pattern is in an allowable range; and forming a resist pattern on a patterning object using the selected resist when the error range is in the allowable range. The multiscale simulation may use molecular scale simulation, quantum scale simulation, and a continuum scale simulation, and may model a unit lattice cell of the resist by mixing polymer chains, a photo-acid generator (PAG), and a quencher.
