Embodiment
[0051] Such as figure 1 As shown, the present invention provides a method for accelerating the simulation of overcoming the rapid transfer of surface species in heterogeneous catalysis, comprising the following steps:
[0052] 1) Start the simulation and initialize the catalyst crystal grid model;
[0053]2) The events in the heterogeneous catalysis process are divided into fast events and slow events. The classification methods include manual classification and program automatic discrimination: 1. Manual classification is to add the fast domain in the configuration file defining the event. If it is True, then If it is False, it is a slow event; 2. Automatic discrimination is to judge that if the forward and reverse process of an event occurs n times in a row, it will be automatically judged as a fast event, where n is a preset parameter;
[0054] 3) Traverse the surface sites for event matching, create a corresponding slow event probability list for the slow event list, and ...
