  1. Hi all, I am running a reactive transport model where I apply a vertical and horizontal fluid to a reactive transport model that contains a variable abundance of hydroxyapatite. However, when the fluid it applied, the whole domain (approx. 800 x 20 m) becomes undersaturated w.r.t. hydroxyapatite almost immediately. When applying a fluid that is undersaturated I would expect this to happen, but over a much slower timescale. Attached is the X2t file. Any advice would be appreciated. Thanks, Sam Bingham 2D_RTMTest.x2t
  2. Hi, I am trying to create a 2D reactive transport model that has an inlet fluid from the x direction, and a different fluid from the y. It appears that GWB only allows an inlet fluid in enter through the left and outlet at the right (i.e. along the x-plane). Is that correct or is it possible to have an inlet from the x and the y? Thanks for any help, Sam
  3. I would like to utilize the mulitcore capabilities of GWB v. 8+, and while reading about this feature in the GWB transport manual, I became curious as to how the parallel algorithm actually subdivides the domain. I understand that the domain is broken into threads of m blocks, each containing n nodes. Each core handles a block, m, but I am wondering how the nodes the physical and chemical data are transferred between m1, m2, m3, etc. I think that with the Operator Splitting Method all transport terms are solved first, mobile species are redistributed, then the ensuing chemical reaction terms are evaluated. Obviously the spatial arrangement of the nodes matters, so how will the nodes in block m1 share data with m2, m3, etc? And how can I be sure that mass and charge balance are preserved?
