About the toughreactEco2n v1.2 not have the “savechem”files

Hello everyone,

I was using TOUGHREACT V1.2 to run a initial progress of HC field(no thermal field). There were some problems when adding the chemical field, my specific simulation process is as follows: (the relevant parameters and files are all based on the simulation of a set of successfully runed files , I just reset the grid and modified the some of the information in  chemical.inp as well as the solute.inp files):

    (1) A simple 2D model was constructed using meshmaker, with 80 1m cells in the x-direction and 40 1m cells in the z-direction (subsequent simulations did not consider layering, and used the default designation "1" for the soil layer):

   (2) Use eco2n.exe to balance the gravity of the flow field, select the lowest cell on the boundary and set it as inactive, and then run successfully to get the "save" file;(I use this module to get a separate flow field information);

   (3) The time information of save was deleted as the flow field information for chemical field initialization;

    (4)Then ,based the original chemical.inp and solute.inp files, I modified the initial mineral zones in the chemical.inp file and deleted some no need information in solute.inp;

   (6) Finally, I run the toughreacteco2n module in combination with mesh, save, flow.inp, chemical.inp,solute.inp, etc., and eventually failing to get the correct output, only the blank document with the corresponding name is output (with the exception of the saveinchem file, which is not visible).

So I'd like to ask guys, where exactly is the problem according to this process? (Attached are the mesh creation and gravity equilibrium processes that were successfully run, and the chemical field equilibrium that had problems, respectively)
