Abstract: Methods for creating and using space-time surrogate models of subsurface regions, such as subsurface regions containing at least one hydrocarbon formation. The created surrogate models are explicit models that may be created from implicit models, such as computationally intensive full-physics models. The space-time surrogate models are parametric with respect to preselected variables, such as space, state, and/or design variables, while also indicating responsiveness of the preselected variables with respect to time. In some embodiments, the space-time surrogate model may be parametric with respect to preselected variables as well as to time. Methods for updating and evolving models of subsurface regions are also disclosed.

Abstract: A method of analyzing the durability of a structure. Load-controlled testing is performed on samples of a composite material of the structure to relate critical strain invariants of the material to cyclic rates of strain invariant accumulation and frequencies associated with the cyclic rates. The material is characterized based on effective properties of the material, including the cyclic rates of strain invariant accumulation. Laminate properties and a geometrical definition of the structure are used to obtain a parametric model. Material characterizations are used to determine model element frequency responses to applied load conditions. Each element's frequency responses and critical strain invariants are used to determine whether damage is indicated at the element. Progression of damage is tracked and accounted for in the model.

Abstract: The present invention is achieved as software which operates on a computer system and which performs calculation by receiving various data as inputs, and which outputs values. The present invention is applicable to a coarse-grained system architecture model including the foregoing event-driven simulation and receives, as inputs, execution time T and the number of memory accesses, N, in the simulation step of the model. Thus, various estimates at the occurrence of memory access conflict are obtained at a simulation speed sufficient for evaluating the effect of the memory access conflict and comparing it with many alternative architectures without information on the correct timing of memory accesses in consideration of memory synchronous accesses and arbitration. The results of this simulation are estimated simulation-step execution time T? under memory access conflict and memory-bandwidth utilization factors {U?i} in individual simulation steps under memory access conflict.

Abstract: In one embodiment, a computer-implemented method for transforming a CAD model of an object between engineering states includes generating a first reference geometry to represent a first engineering state. A parametric CAD model of the object may be generated to represent the object in the first engineering state by constructing the parametric CAD model as having dependence on the first reference geometry. A second reference geometry may be generated to represent a second engineering state. The parametric CAD model may be regenerated to represent the object in the second engineering state by replacing the first reference geometry with the second reference geometry.

Abstract: Mesh generation and editing tools are provided. The mesh generation and editing tools can be implemented using MATLAB® and are platform-independent, usable in any number of different operating systems and configurations. The mesh generation tool uses a graphical user interface to receive user inputs of boundary and bathymetry information and automatically generates a mesh based on the input information and user selections of the number of mesh refinements based on the bathymetry that should be run. The mesh generation tool also performs a check of the computing resources needed to construct a mesh with the selected parameters and allows the user to change the parameters before generating the mesh if necessary to avoid excessive resource use.

Abstract: A method for retrodicting source-rock quality and/or paleoenvironmental conditions are disclosed. A first set of system variables associated with source-rock quality is selected (705). A second set of system variables directly or indirectly causally related to the first set of variables is also selected (710). Data for variables selected to be known quantities are estimated or obtained (720). A network with nodes including both sets of variables is formed (715). The network has directional links connecting interdependent nodes (715). The directional links preferably honor known causality relations. A Bayesian network algorithm is used with the data to solve the network for the unknown variables and their associated uncertainties (725). The variables selected to be unknowns can be input nodes (paleoenvironmental conditions), intermediate nodes, output nodes (source rock quality), or any combination thereof.

Abstract: A configuration manager identifies a first device and a second device within a simulated system. Each device within the simulated system includes an inbound port and an outbound port. Next, the configuration manager injects a simulation only packet, at an “outbound time,” on the first device's outbound port and detects that the second device's inbound port receives the simulation only packet at an “inbound time.” As such, the configuration manager identifies a direct connection between the first device and the second device and computes a latency time for the connection. In turn, the configuration manager configures one or more first device configuration registers and one or more second device configuration registers based upon the computed latency time.

Abstract: A set of parameters used in a model of a spectrometer includes free parameters and fixed parameters. A first set of values for the parameters is set and the model is used to generate a first spectrum. A value of one of the fixed parameters is changed and a second spectrum is generated. An inverse of the model of the spectrometer is then applied to the second spectrum to generate a set of values for the parameters, the values being the same as the first set of values except for one or more of the free parameters. If the free parameter has significantly changed the fixed parameter is designated a free parameter.
