When I initialize the UDS in the water phase as > 0, and UDS in the gas phase = 0, then UDS in the water phase doesn’t change, but UDS in the gas phase grows<\/li>\n
When I initialize the UDS in the water phase as > 0, and UDS in the gas phase > 0, the UDS in water phase doesn’t change, but the UDS in gas phase drops to 0 in the first step and stays there.<\/li>\n
