Line 95: = My HPC model uses double precision due to unstable 1D channel. How can I make it stable in single precision? = ~~Unfortunately~~Currently, it is not possible to run the 1D ESTRY engine in double precision and 2D TUFLOW engine in single precision for the same model. There are two ways how to reduce the mass balance errors and switch to a single precision: * Improve stability of the 1D features and 1D/2D links for it to perform well in single precision. The _TSMB and _TSMB1d2d layers might help locating specific features that could be worked on. * Remove 1D channel completely and use Quadtree mesh to sufficiently refine resolution of the creek in 2D.
