Abstract: Disclosed is a method and system for identifying simulated basin results and associated input parameter values for simulation of geographic basins by a stratigraphic forward model simulation program that are most likely to represent the actual basin by treating inputs and outputs of the stratigraphic forward model simulation program in a unified manner. An embodiment may calculate probability distributions for input parameters and validation data, and calculate likelihoods of simulated basins as a combination of the combination of the probabilities of the input parameters used to create the simulated basin and of the combination of the probabilities simulation validation results of the simulated basin. An embodiment may then select most likely simulation model result basins based on the results having a higher calculated likelihood. The most likely simulated basins may be used for analysis of exploration and/or production decisions without the need for additional, expensive testing on the actual basin.

Abstract: One embodiment of the invention provides a computer-implemented method for discrete element modelling of a plurality of discrete elements corresponding to particles and physical geometry elements. The modelling performs a simulation through time of physical interactions of the particles with each other and with the physical geometry elements in a three-dimensional space. The method comprises providing a plurality of discrete element material models, each discrete element material model corresponding to a respective bulk material and containing (i) information regarding the properties of particles within said bulk material, and (ii) information regarding the behaviour of interactions between such particles. The method further comprises receiving from a user: (i) a selection of a bulk material for use in a simulation, and (ii) a specification of properties associated with the selected bulk material. The method further comprises generating a set of particles of the selected bulk material for use in the simulation based on (i) the discrete element material model for the selected bulk material, and (ii) the properties of the bulk material specified by the user. The method further comprises performing a discrete element model simulation on said set of particles, wherein the simulation uses the information regarding the behavior of interactions between particles from the discrete element material model for the selected bulk material.

Abstract: The present invention is notably directed to a computerized method for providing real-time feedback to a user from states of a model physical system, or MPS, via a computerized system comprising one or more processors and a user interface system, or UIS. The method comprises the following steps, each performed via the one or more processors. Configuration inputs are repeatedly received, to modify a configuration of the MPS, said inputs including user inputs received via said UIS. While receiving said configuration inputs: configurations of the MPS are updated based on the configuration inputs received; and a state of the MPS is repeatedly computed, whereby each computed state corresponds to a latest updated configuration that was available before starting to compute said each computed state. While repeatedly computing a state of the MPS: a surrogate function is obtained, upon completion of each computation, which surrogate function approximates a function of said each computed state; and at least one type of feedback is repeatedly provided via the UIS in respect to said user inputs received. Said at least one type of feedback is provided by sampling the configurations being updated and by evaluating a last surrogate function obtained, and/or a function derived from it, according to the sampled configurations, at a frequency compatible with real-time user-interactivity. The present invention is further directed to related computerized systems and computer program products.

Abstract: Computer-aided methods for simulating confined nanodevices are disclosed. In example implementations, atomic-scale model of the nanodevices are generated so that dimensions and materials are specified. Then, band structures which comprise wave functions and Eigen energies are calculated using First Principles Methods (FPM). Effective mass modeled which comprise wave functions and Eigen energies are generated. After that, spatial wave functions of the calculated FPM band structures are mapped to the generated effective mass band structures wave functions by considering global behavior. In response to the mapping, generated effective mass models are fitted to calculated FPM energies so that approximate electronic band structures of the confined nanodevices are modeled. Computer programs for carrying out the methods, data media and computer systems are also disclosed.
