Q1：請問PetraSim軟體能夠輸出和輸入TOUGH2及TOUGHREACT的資料嗎?
A1：PetraSim does not import TOUGH2 or TOUGHREACT models created outside of the interface. The mesh really needs to be generated in PetraSim in order for it to be visualized in the program.
A2：PetraSim will not import DAT file or TOUGHREACT input files for models created outside of PetraSim. This is mainly because the true mesh geometry is not stored in these files.
You could use PetraSim to create meshes and input files that you could then use with your own compiled executables.
Q3：想請問在TOUGH2設定中的, Time step (DELTEN)是指每個step的計算時間嗎?
例如100s就是每個Time step為100秒.Max Num Time Step (MCYC)是指迭代的最大次數嗎?
A3：DELTEN is the length of the first time step in the simulation. If the user has the automatic time stepping turned on, this will likely change as the model progresses.
MCYC is the max number of time steps, not the maximum number of iterations. For example, if the user enters MCYC of 200, the simulation will halt after 200 time steps, even if the end time is not reached. NOITE is the maximum number of iterations allowed in a time step.
Q4：ECO2M的使用者手冊,提到ECO2M計算水-二氧化碳-鹽系統平衡的溫度範圍是攝氏12°C ~ 110°C,
想請問如果模擬溫度大約是120°C左右的情況,ECO2M能夠正常運算嗎?
還是需要另外做特別的設定呢?
A4：在較高的溫度下，結果會不正確。

Unfortunately, at this higher temperature he may get unreliable results due to the partitioning portion of the code (which is based on lower temperatures). I would suggest that he contact the authors of TOUGH2 at LBNL to see if they think he will get reliable results at a slightly higher temperature. The TOUGH2 forum might be a good place for this type of question: https://tough.forumbee.com/category/y6kz6
