Simulation systems are important tools for the development of training tasks in different application domains. The use of military simulated problems (MSPs) in simulation systems allows the introduction of challenging decision making situations to military trainees so that they can exercise their skills. To support the implementation of such MSPs in an artillery battery simulator, this work investigates how to compute dynamic changes, such as flooding-driven modifications, into the hierarchical and irregular navigation grid structure expressing the environmental characteristics of large virtual terrain scenarios. The paper describes an efficient mechanism to process these modifications during simulation runtime, without affecting the overall system response time, thus the user interaction with simulations. Experimental results show that the proposed techniques are able to handle time-constrained modifications of large virtual terrain scenarios.
