Maxiter values for iterative solver (how much accuracy) #20

Open mcr222 opened 8 years ago

mcr222 commented 8 years ago

Maxiter value determines how many steps does the gmres (currently our most expensive operation) take to return an approximated result to the system. The best maxiter value should be investigated, as it determines the trade-off between solution accuracy and execution time). Current value is set with a wild guess (and few observations).

Functions to modify: _euler_semiimplicit _midpoint_semiimplicit

Code TODO comment (remove once issue is closed):

TODO: choose an appropriate maxiter parameter to distribute work between taking more steps and having a

more accurate solution
