Learning outcomes |
The overall objective of this course is to provide students with a digital laboratory environment where they can learn and practice numerical modeling and computational simulation applied to Fluid Mechanics. Students will develop skills in the following areas:
-Numerically solving basic Fluid Mechanics problems by formulating and implementing ordinary differential equations (ODEs) in Scilab or Matlab.
-Understanding and applying the fundamental steps of a CFD simulation, including pre-processing, computation, and post-processing.
-Using commercial and open-source software, such as ANSYS Fluent and SOLIDWORKS Flow Simulation, to perform numerical simulations of fluid flows.
-Critically analyzing computational simulation results by comparing them with analytical solutions and experimental data.
-Developing skills to assess numerical errors and interpret the impact of modeling choices on result accuracy.

Teaching Methodologies and Assessment Criteria |
The evaluation of this course is based on two main components: quizzes/frequency tests and computational assignments (TPCs) or digital fluid mechanics experiments.
Final grade: 0.25 × Quizzes + 0.75 × TPCs/Digital Experiments.
To access the exam: Quizzes = 7/20 and TPCs = 7/20.
To pass: Final grade = 9/20, with Quizzes = 9/20 and TPCs = 9/20.
At least 60% of TPCs must be submitted, and 80% attendance is required.
only the QUIZZES are possible to be improved during the exam. and the Final grade at the exam will be:
Final grade= 0.25 × EXAM + 0.75 × TPCs/Digital Experiments.
TPCs are individual, evaluated through reports, simulation files, and if necessary, an additional examination of the reports will be requested.
