Abstract: A computer system is configured to manage a value of a variable via firmware. Managing the value of the variable includes detecting a system management interrupt (SMI), causing the computer system to enter a system management mode, in which a request associated with the SMI is handled by the firmware. In response to determining that the SMI is generated by a baseboard management controller (BMC) and that a cause thereof is associated with reading or writing a value of a variable, one or more parameters associated with the variable are obtained from the BMC. Based on the cause of the request and the one or more parameters, the value of the variable is read or overwritten with a new value. The value or the new value is then sent to the BMC, which in turn passes the value or new value to a second computer system over a network.

Abstract: The present disclosure provides a numerical simulation method of pulsed laser paint removal and a use thereof. This method establishes a three-dimensional (3D) temperature field model by ANSYS software to perform a numerical simulation of nanosecond pulsed laser paint removal. A high-speed moving pulsed laser is loaded on a surface of the model in a form of heat flux, and a coordinate system is moved to realize loading on different paths. A special surface mesh screening method is used to realize loading on any surface, and it ensures that laser energy distribution on a material surface is in line with reality. In addition, an element birth/death technology is combined to remove an element that exceeds a threshold, so as to intuitively present the surface morphology after laser paint removal. The present disclosure can realize the prediction of the contour of a paint layer ablated by a pulsed laser.
