Physical system simulation

A method of physical system simulation, the method comprising:

• generating initial simulation data by providing first sets of first values of first input parameters to a simulation of a physical system, each set of the first sets indicating a first value of each of the first input parameters;
• developing at least one surrogate model based on the initial simulation data;
• selecting second input parameters from the first input parameters based on the at least one surrogate model, wherein a count of the second input parameters is less than a count of the first input parameters;
• generating second simulation data by providing second sets of second values of the second input parameters to the simulation, each set of the second sets indicating a second value of each of the second input parameters;
• and
• developing at least a second surrogate model based on the second simulation data.

A computer-readable storage device storing instructions that, when executed by one or more processors, cause the one or more processors to:

• generate initial simulation data by providing first sets of first values of first input parameters to a simulation of a physical system, each set of the first sets indicating a first value of each of the first input parameters;
• develop at least one surrogate model based on the initial simulation data;
• select second input parameters from the first input parameters based on the at least one surrogate model, wherein a count of the second input parameters is less than a count of the first input parameters;
• generate second simulation data by providing second sets of second values of the second input parameters to the simulation, each set of the second sets indicating a second value of each of the second input parameters;
• and
• develop at least a second surrogate model based on the second simulation data.
