PhreeqcRM initializaion

[Yongqiang]

Dear Phreeqc experts,

When I read through the test code delivered with PhreeqcRM. I saw the following example code. I don't understand the role of "DELETE; -all". Will this delete all the reactants from "RM_RunFile" and leave empty cells?

      status = RM_RunFile(id, 1, 1, 1, "advect.pqi");
      strcpy(str, "DELETE; -all");
      status = RM_RunString(id, 1, 0, 1, str);

There are three sets of IPhreeqc instances: the workers, the initial IPhreeqc instance, and the utility instance. The last line deletes all solutions and reactants from the workers and the utility instance. TThe utility instance is unlikely to be used. The workers ultimately contains all the information about the cells of the model, so deleting everything could be done just before transferring the cell values from the initial instance to the workers with InitialPhreeqc2Module, just to make sure there are no stray definitions left over from previous RunFile or RunString calls that affected the workers. Note that SELECTED_OUTPUT, USER_PUNCH, and database definitions would not be deleted.

Dear Parkhurst,

Thank you for your promote guidance. It is really helpful. Just to confirm a guess. When reading the PhreeqcRM document, the mentioned workers and utility refer to the reaction module (Phreeqc) and flow module (e.g. Comsol or OpenFOAM). Is it correct?

No, please reread my previous post.

I found the answers in this post. I put it here in case anyone needs it.
