Unbounded viscosity and density #469

Closed wennanlong closed 2 years ago

In Reservoir Tab, cell M58. The initial formula is μ=K1eX ρY. I check the paper from Lee et al. (1966). This formula will become unbounded if the natural gas density is > 1 g/m3. When fluid has an extremely high viscosity, it is unlikely to flow. So the bottom flow pressure always indicates ERROR which causes the endless loop.

I now limit the density to a maximum of 0.9 g/cm3 so that correlation will not break.
