Yes, we can publish articles based only on numerical simulations. But, it is necessary to validate your results by a comparative study with other articles which makes it possible to validate your work.

Dear Mohammed,

many journals would publish purely numerical results. Some of them are purely mathematical like SIAM Journal on Scientific Computing, some of them belong to some specific field of application like e.g. Computer Methods in Applied Mechanics and Engineering. The key point for acceptance is the scientific novelty of your paper, which means that either your simulation results use an establish simulation technique and reveal some new effect or explain other experimental results available in the literature, or that you mainly focus on some new method of computation or a new mathematical model and the computation results merely demonstrate the good properties of this new simulation strategy. In the latter case, a comparative study with some other reference results available from the open literature or from computations using commercially available software should generally also be performed and discussed.

General hint: each journal has a website with an "Aims and Scope" section, from which you can learn, whether your specific manuscript submission would be considered suitable for the journal by the editors. Often you can also see the acceptance rate and other metrics of the journal, from which one can estimate the chances of successful publication.

Yours

Yury
