I have a model where I need to use fluid cavity and fluid exchange. During structural model creation, I'm able to determine the fluid cavity surfaces and fluid exchange model. But when I open mechanical scenario creation app, I'm only able to create cavity pressure, but how I could create fluid exchange activation with predefined amplitude? Currently I can do that by exporting inp-file, manually modifying it and running simulation using Simulation Manager app, but is it possible to do directly in mechanical scenario creation app?
