      Most of the points in this course come from Research Assignments which are made by Research Groups.

      Materials for the Research Assignment 1 are available now (Saturday 20.1.2024).

      Calculation exercises (starting on Friday) are voluntary sessions during which you can practice your skills in calculations.
      We will use Mathcad as the calculation tool in a) exercises and in b) Research Assignments.
      Materials available for the 1st session. Equation collection and Template 1.

      Mathcad Instructions:

      Mathcad should be available in Aalto's workstations (also remotely), check course's Calculation exercises (later) page for instructions.

      Remote usage of Aalto's workstations

      Check the page and possibilities, if you find it interesting:

      More info:  -> Etätyö - VPN ja VDI  (FI)  -> Remote Work  (ENG)

      Mathcad should be found in Maari-C computers at least! We will check this!

      However, you can get a free version for your own PC

      a) at first 30 day full version

      b) after 30 days -> limited express version
