摘要： A method of designing a material by optimising values for a plurality of design variables is provided. The method including the steps of:
(i) providing one or more property models, the i th property model (where i is an integer from 1 to n prop , the number of property models) producing a prediction P i for a value of a respective property of the material as a function of the design variables, and further producing a value for the uncertainty σ i in the prediction P i ,
(ii) for each property, setting a specification target T 0,i for a desired value of the property and a probability p i for that specification target T 0,i to be met or exceeded,
(iii) for each property, determining a probabilistic target T i for a value of the property, the probabilistic target T i being based on the specification target T 0,i and the probability p i , and further defining a merit index factor G i based on the degree to which a given prediction P i satisfies the probabilistic target T i ,
(iv) constructing an overall merit factor G from the individual merit index factors G i of the properties, and
(v) determining a set of optimal design variables that optimise the overall merit factor G.

摘要： A neural network is trained for, and may be used in, the simulation of the fluid flow through a domain around an object geometry. A first training process for the neural network includes training (902) the network on a first set of encodings of pre-computed computational fluid dynamics (CFD) simulations for object geometries and associated boundary conditions. The first training process uses a first loss function that evaluates an error between the network output and the pre-computed CFD simulations. A second training process is then carried out which includes training (905) the network on a second set of encodings of object geometries and associated boundary conditions. The second training process uses a second loss function that evaluates an error between the network output and a set of fluid dynamics conditions.
