File Information

Description

The Spectral Element Method combines the accuracy of spectral methods with the geometrical flexibility of finite elements. The SEM is widely used in computational fluid dynamics and has been succesfully applied to problems in Seismology ranging from regional to global scale wave propagation and earthquake dynamics.

SEMLAB is a set of scripts intended for tutorial purposes. Problems solved include wave propagation and dynamic earthquake rupture in 1D and 2D.

For production codes in Fortran/MPI please refer to SEM2DPACK or SPECFEM3D.
