This work presents a collaborative modeling strategy on the web through the WebSocket network communication protocol. To understand the relevance and identify possible gaps on the subject, an investigation was carried out on the state of the art of collaborative web applications through a systematic review of the literature. To demonstrate the proposed strategy, a proof of concept was developed using the JavaScript and Python programming languages. The proof of concept has a client-server architecture, in which the client communicates with the server, which is responsible for hosting the application s topological data structure, allowing the creation of two-dimensional finite element models. Due to the two-way communication channel provided by WebSocket, the collaboration between several users in virtual rooms that share the same model in real-time is possible. In the end, an evaluation of the usability of the application is carried out to verify the proposed strategy and find possible limitations.
