“…In ODEs_PDE.m the ODEs system is written together the discretized boundary conditions. Finally, principal_PDE.m also manages the data file, solves the ODEs system, plots all the figures and does some videos that show the temporary evolution of variables profiles, making easier the correct analysis of the results [3].…”

If we analyse some of the specific skills of Chemical Engineering degree, and it would not be very different in other disciplines of engineering, the verbs design, analyse or simulate stand out above all. In essence, calculating is an intrinsic activity for the engineer and, therefore, for engineering students.How is this activity developed? When we face a real problem we translate it into mathematical language (modelling). We solve the resulting mathematical problem to obtain the mathematical solution (simulation). The analysis of the results allows us to extract information from the real problem. If the interpretation of the results does not fit with the real problem studied, we must rethink the mathematical model obtained, and so on.Teachers often restrict the real problems that students face to simple situations so that the resulting mathematical problem is simple and, if possible, provides an analytical solution. Why should we do this today if we have numerical methods, a big computing power and mathematical software available to our students? Examples of complex mathematical problems arise from analysis and design of heat exchangers, chemical reactors, distillation columns, etc, both in steady and transitory regimes. These mathematical problems can be classified in groups: solving algebraic equations, ordinary differential equations or partial differential equations systems.According to this classification, some teachers of the Chemical Engineering degree at Campus of Alcoy are providing our students with Matlab guide templates to solve these types of mathematical problems, regardless of the subjects in which these problems appear. This action makes it easier for students to face real problems by reducing the mathematical difficulties associated.This paper shows how these Matlab guide templates are and how students use them in different subjects. It allows students to focus on the engineering aspect of the processes, leaving the difficulty of the associated mathematical problem in a second plane. It also makes easy to modify process parameters to quickly see the effect on the main variables of the process (what if? analysis). Consequently, students improve their ability to analyse and interpret the results obtained and their critical thinking skills. And, finally, they know useful computer tools that can be used both academically and professionally.

“…Today there is general purpose mathematical software, such as Matlab, that allows you to quickly solve different types of mathematical problems, such as they can be systems of algebraic equations. However, if the user does not has adequate competence in computer programming and numerical methods, the existence of this mathematical software is not appreciated as a help and its use is not even contemplated [1].…”

The resolution of material balances is one of the main activities both in Chemical Engineering studies and in the development of the profession. Their resolution translates into a system of algebraic equations that can be quite complex. For its resolution, it is necessary to use mathematical software, as is the case with Matlab. However, students may have a deficit in programming skills with Matlab.To solve this deficit, students have been provided with a Matlab template, where the student only has to enter the main parameters of each material balance in order to obtain a mathematical solution. With the aim of knowing the acceptance of the mentioned methodology for the mathematical resolution of material balances, a survey has been provided to the students, where anonymously, they respond, at the end of the subject, their main views on the matter. Key questions such as the usefulness of the methodology, the degree of use, personal assessment, and the relationship between the use of the Matlab template and understanding of knowledge, allow teachers to determine the strengths and weaknesses of the new methodology.
