Computation Time and Peak Memory

Computation time and memory data consist of the computation time for the different stages of the solution such as checking the geometry and matrix calculation time. The peak memory and memory per process is also provided.

The final section in the output file gives an overview of the computation time, in seconds, in a

tabular format:
