I am trying to study the fluid 1 displacement by fluid 2 using general scalar simulation for a given volume. I have few questions as follows
1. for a given boundary conditions the given volume should be filled in 0.011 sec but when i run it. it takes around 0.05 sec. I dont know why it is taking so long time. can anyone explain.
2. How to calculate the volumes of fluid 1 and fluid 2 after iam done with my simulation using scalar value. or may be concentration of fluid 1 and fluid 2.
I can try to help you out here.
- What are the fluids and what value are you using as the diffusion coefficient? Do you have Intelligent Solution Control turned on or off?
- I will have to leave this one to someone else as I do not think we can actually do this. We can meausure the scalar (which you can convert to concentration by hand) on a cut-plane but I'm not sure we can give you a ratio within the fluid volume.
Hopefully that helps you a little and with some more information on point 1 we might be able to help more.
You can capture the scalar on a cut-plane and should be able to convert it to a concentration just using the ratio of Air to CO2. As far as I know, there is no way to do this per volume.
Happy to take a look at your CFZ (support file) if you think it might help.
