Limitation to the number of VOCs ?

Hi everyone,

I am currently running simulations with 8 VOCs (plus air and water) and I want to add 6 more VOCs.

I modified the T2 file like so:

- MNEQ = 17 (16 components + one energy balance equation)

- MNK = 16 (14 VOCs, 1 NCG and water)

Unfortunately, the application stops before running. I checked that the MULTI records are like this:

16 16 3 8 10 (I inject 6 more VOCS in a 10-component isothermal system)

I read in the manual that "there are no intrinsic limitations to the number of NCGs or VOCs in the TMVOC formulation; arrays for fluid components are currently dimensioned as 20, accommodating water plus 19 components that may be NCGs or VOCs. NCG arrays are dimensioned as 10."

Is there a limitation in the source code for the number of VOCs?

 

Thank you in advance, the TOUGH community, for your help,

And I wish you the best for this new year!

Cheers,

Quentin

  • Hi Quentin,

    Please clarify what you mean by "stops before running"  (you cannot stop unless you are running, right?).

    Here's my most asked forum question: What is the error message?

    Hi Stefan!

    Here the message I got from the prompt command and the .out file.

    I meant it did not run as the simulation stopped after enumerating the domains.

     

    I just understood that it is not related to the number of VOCs but to the physico-chemical properties of the others "VOCs" (actually, they are alcohols) I need to inject.

    Here are the properties for the alcohols I want to inject, just in case you see any mistakes...

     

    Most of the data comes from the Appendix A in Reid et al. (1987).

    There are only mistakes in ISOPROPANOL and the PENTANOL records.

    I have to double check them.

    Sorry for this useless post...

  • Hi Giraud,

    I want to model LNAPL distribution by TMVOC. DO you know how can I get the code. I would appreciate if you can send me TMVOC code. 

    My email: khodaeik@yahoo.com

    Regards,

    Kamal
