That is the reason for the reformulation as then there is always correct sense of diffusion thanks to specifying final conditions on negative x half-domain, instead of initial ones. | |

For instance, the OP was suggesting to solve the forward heat part with an initial condition, and the backward heat part with a final condition. | |
