N2 - Thickening consists of separating parts of a suspension by sedimentation under the force of gravity, to obtain a denser product and a clarified liquid. Depending on which part is needed to recover, the denser product or the pure liquid, we use the term thickening or clarification to define these operations. Thickener design is compulsory for chemical engineering (CE) curricula and is usually introduced in courses related to unit operations. Thickening design problems are solved by geometric methods (e.g., Coe–Clevenger or Kynch–Roberts methods). However, nowadays, computers play a more and more important role in CE practice. Both specific and general software solutions are essential. Whereas CE-specific software is adequate for graduates and professionals, general mathematical software can also be used in class. They can help to deliver certain competences included in the vast majority of CE curricula. For CE introductory courses, software with integrated functions and friendly interfaces are generally preferred over those that require to be familiarized with programming languages. Here, we describe the use of SMath Studio in 2nd-year engineering courses by nonfamiliarized students. SMath Studio is a comprehensive mathematical notebook, similar to Mathcad, but it is entirely free for personal or commercial use. In this study, student's opinion was surveyed. Around 70 students took part in the two-phase survey. The use of SMath allowed students to better understand the theoretical basis, fostered critical thinking, and increased their motivation to apply this software for solving other engineering problems.
