These are the finite difference methods in splitting environment, namely, operator splitting nonstandard finite difference (OS-NSFD) methods that effectively deal with nonlinearity in the models and computationally efficient. Positivity of both the proposed splitting methods is proved mathematically and verified with the simulations. A comparison is made between proposed OS-NSFD methods and well-known classical operator splitting finite difference (OS-FD) methods, which demonstrates the advantages of proposed methods. Furthermore, we applied proposed NSFD splitting methods on several numerical examples to validate all the attributes of the proposed numerical designs.eninfo:eu-repo/semantics/openAccessStructure Preserving Numerical Analysis of Reaction-Diffusion ModelsStructure Preserving Numerical Analysis of Reaction-Diffusion ModelsArticle202210.1155/2022/51283432-s2.0-85127599666WOS:000790465900002Q1Q1
