Embodiments of methods, systems, and computer-readable media for coupling two or more simulators to simulate a coupled multi-physics model of a subsurface formation are provided. A coupling framework loads one or more simulators as shared libraries into a common process and a common memory space with a first simulator to create the coupled multi-physics model of the subsurface formation. During simulation, the coupling framework controls data exchange between the first simulator and the other simulator(s) through the common memory space and controls execution of the first simulator and the other simulator(s) responsive to the common process. In the event of two-way coupling, the coupling framework can receive feedback from the other simulator(s) and alter execution of the first simulator. In the event of grid misalignment, the coupling framework can map data between the first simulator and the other simulator(s) such as in a globally conservative (e.g., mass, energy, etc.) manner.

The educational system for teaching mechanical failure includes first and second specimen pieces. The first and second specimen pieces are adapted to be magnetically joined to one another at a selected magnitude of magnetic force. A linear force measuring device, such as a load cell, is secured to the first specimen piece and a support frame. A linear actuator is secured to the support frame and the second specimen piece to selectively apply a separation force to the first and second specimen pieces. In use, a user may increase a magnitude of the separation force until the first and second specimen pieces separate from one another. The measured separation force when the first and second specimen pieces separate from one another is representative of a required force to cause mechanical failure.

The present invention relates to a demonstration device enabling the contrast of mask filters comprising a cabinet wherein a dust cavity and a demonstration cavity with right opening are formed with a partition plate. On the partition plate is set a communication port to communicate the dust cavity with the demonstration cavity. On the upper part of the demonstration cavity, are set a dust collecting movable motor and a dust collecting movable screw which cooperate with each other, and on the said dust collecting movable screw, a dust collecting movable block is fixed by plug push cooperation. To the lower end of the dust collecting movable block, a dust collecting rotary motor is installed and under the dust collecting rotary motor, a dust collecting frame is installed. In the middle of the dust collecting frame, a dust collecting partition plate is installed. On the bottom of the dust collecting frame and on both sides of the dust collecting partition plates, dust collecting contrast blocks are installed. On either right and left sides of the dust collecting frame, a mask filter and contrast device which use masks to function which are both connected to the inner cavities are respectively installed. Both the mask filters and contrast devices are connected to the communication port. The present invention may directly present the dust-proof effects of the mask filters compared with common facial masks and achieve good teaching experience.
