Trying to see if I could make any changes in the simulation settings to make it less memory-consuming, I saw there is an option to enable a convolution-solving method. When I used it, it took much more time (about 24 hours of simulation) but it handled to do it without running out of memory.<\/p>\n<p>I want to have a better understanding of the implications of using either the default solving method (which I believe uses state space) or the convolution-solving method. Are they equivalent in terms of results accuracy?
