Format of file where pressure changes over time

Hello Everyone,

I am working on another model where pressures will change over time. I am looking through the manuals for the TOUGH code and am wondering if you could direct me to a specific location where the format for temporal pressure changes may be found.

    I am trying to input a data from a table but have no clue how the values need to be configured to be read through the system.

    Search for TIMBC in the User's guide. Good luck.

       Thanks for responding! I searched for it in the user manual but nothing came up, however I did find the section on "Boundary Conditions and “Inactive” Elements". Is this where you were directing me? 

      For context I am trying to simulate the effect of barometric and hydrostatic pressure fluctuations on the pumping of Methane from beneath a low permeability capillary barrier.  

      Is it possible to temporally change both pressures for the model? Would I use a similar method to the one described in the "Boundary Conditions and “Inactive” Elements" section?

    Hello again,

    Yesterday I attempted to use the TIMBC block to provide a change in pressure at 9 different times.

    I changed MOP (21) for TIMBC use, and followed the format outlined in the user manual to the best of my knowledge. 

    However, I am unable to see any changes in pressures at the element at the times specified. 

    I have attached the infile to this chat for your review, can look over the infile and let me know what may be the issue.

      Dr. Zhang, thanks again for providing an update to our initial conversation. 

      I was wondering if you had some time to review my most recent comment. 

      I attempted to follow the directions from the TOUGH3 user manual but to no avail. 

      What do you think the issue is?

       I did not check the format but I see you have "B53  " as an element name, which I suspect checked you had "  B53" as element name in the MESH. In addition, you did not provide a large volume to keep the pressure.

      I suggest you go through the users guide to understand TOUGH inputs before you start your own simulations, which I think will help you to speed up your projects.

      Tank you,

      Yingqi
