temporal integration with implicit diffusion #8

Closed p-costa closed 3 years ago

p-costa commented 3 years ago

@nazmas brought to my attention that the explicit part of the temporal integration of the diffusion term, when implicit diffusion is used, is inconsistent with what is reported in the CaNS-GPU manuscript.

Although it may still yield physically sound results, the velocity will not be second-order accurate in time.
