- The FEM can be very efficiently used for parabolic equations. In fact, exhaustive analysis
- have been done for parabolic systems. As suggested, the method of lines (space-part by
- FEM and time-part by finite differences) is the most common way of doing it. However, there
- are other ways to approach the problem. For example, the group led by Claes Johnson at
- Chalmers University, Sweden have used the so-called space-time formulation for diffusion
- equations and have shown that the scheme is of higher-order accuracy (than MOL) and stable.
- Refer to papers in Computer Methods in Applied Mechanics and Engineering . In these techniques,
- the time-dimension is also approxmated the same way as space-dimension.
