GENER block injection fluid

Hello, 

There is an option for injection component on the TOUGH+HYDRATE GENER data block defined by COM1, COM2, COM3, etc. However it doesn't specify how we can inject a particular fluid into an element. So, for example if I am working with methane gas hydrate and I want to inject methane gas into an element, how do I specify if it is methane or water (though there is an option WATE or COM1 for water injection)? 

Or if I want to inject a combination of gases (for example 50% methane and 50% ethane) into that element, how do I do it? Is there an option to define the chemistry of the gases that I am missing so far? Or do I have to tweak the original code for this? Please let me know if anyone has any idea on it.

Stefan Finsterle I'm sorry to mention you here but the TOUGH+ forum is awfully quiet and since the GENER block is also used in TOUGH2, I thought may be you have some answers.

I am using the TOUGH+HYDRATE v1.5 academic license and I haven't made any changes to the original code so far. 

Thanks

    IN TOUGH+HYDRATE, COM1 is water and COM2 is CH4.  The code can only handle CH4 as the hydrate-forming gas.

    George Moridis Thank you Dr. Moridis for the clarification. I still have one confusion regarding the issue. I am using the SS_GROUP option to define a group of injectors and the ssgroup_Time_Series file that is generated is showing zeros for all the columns despite giving a constant rate of injection GX in the GENER block. I have tried both COM1 and COM2 as SS_type. The time series file, however, shows heat rate Q_H when I specify the enthalpy, EX of the injected fluid. 

    Could you please shed some light into that particular issue?

    Thanks

    You are using an older version of the code, with limited capabilities for the description  and monitoring of well production.  I suggest you upgrade your code.

    good day sir. 
    I noticed in the GENER block, u need to assign an element name for the location of the well. Without using ELEME and CONNE blocks how do you do this?

    The inputs in the meshmaker didn’t specify the element but the regions
