Dear friend:

I have a question to ask for you. I want to specify the inlet and outlet in the block center, which look as the injection and production.

As a thought, I think there are two ways. One is that I create two blocks while small one block is looked as the injection. Another way is specifying a cell as the injection in only one block. But whatever, I do not know how to specify injection and production. Could any friend help me please?

Thank you very much.
Best wishes,

Are you referring to injection of lagrangian particles or some eulerian injection?

Hi friend:

Sorry. I mean that I will test the case of the CH4 or CO2 sequestration. So the injection and production should be the eulerian. For example, I want to see the result after injecting 50 years and so on. Could you have any idea please?

Thank you very much,

You need to have some field that represents the fraction of each substance. Then you just specify the inlet patch to have a fixedValue at whatever fraction you're injecting. I am pretty sure you cannot have an internal face injecting things, it has to be a patch on the outside of a block that does not have another block next to it.

But I have to admit, I don't really know much about this.

Hi friend,

Thanks for your useful idea. I have tried with the fixed value for nonuniform such as the U or others to set the initial value as the injection. Do you think this is ok?

Thanks again.
