Student workload

Lecture topics:
Mathematical preliminaries and classical variational methods. 1D- and 2D-interpolation. Numeriacal interpolation. 2D- and 3D solid elements.
Computer exercises:
Course includes three learning assignments. Assingments are done and reported in groups of two. Reports are graded with points. Maximum amount of points from assinments is 3x10=30 point. To pass the course minimum of 10 points is required from the assingments.
Homework:
Homework assignments are graded with points. Maximum amount of points from assinments is 5x5=25 point. To pass the course minimum of 10 points is required from the homework assingments.
