2018年3月21日 · Hello, One of our client asked how to solve the following issue (they can't revise the initial parameters or value) and please refer to the attached file: Solving for initial system. Loaded: 76 aqueous species, 70 minerals, 2 gases, 0 surface species, 13 elements, 0 oxides. Newton-Raphson did not...

1 天前 · During the simulations I faced the following problems, which seem to be rather typical for many GWB users, namely: ... -- Can't converge, abandoning path. -- Xi step is too small 2. Not forming diffuse layer (insufficient ions in fluid) in case when Na+ concentration in Basis is too small (2.09E-04 mol/l) but this value is taken from the field ...

You can download fresh copies of the GWB's thermodynamic datasets, the GWB symbol font, and more. Installation issues For help installing and activating the software, visit our troubleshooting guide .

2019年3月6日 · You can report the factor limiting X2t's time steps by checking "explain steps" in the Config > Stepping dialog, and then "Follow Output" on the Results pane. This might give you a clue about why your run is failing. For more information, please see 9.40 explain_step in the GWB Command Reference.

Use the GWB to create Eh-pH diagrams, calculate speciation in solution, trace reaction paths, model reactive transport in flowing groundwater, and much more.

2024年2月27日 · GWB是The Geochemist's Workbench 的缩写，地球化学模拟软件GWB广泛应用在环境地球化学、油气地球化学以及矿床地球化学等领域。 本文列举了一些使用 GWB 软件的常见问答，或许会有您要找的答案。

The tutorials below show how you can use The Geochemist's Workbench ® to quickly solve a variety of problems in geochemistry. Click on an image to launch the corresponding tutorial. If you have installed the GWB software, click on the icon shown underneath each diagram to download an input file pre-configured to calculate the diagram shown.

The Geochemist's Workbench® has from its introduction in 1991 set the standard in geochemical modeling. With its crisp user interface, fully integrated graphics, highly optimized algorithms, and advanced software architecture, the GWB makes quick work of geochemistry tasks small and large. Already a GWB user?

2015年8月30日 · When I suppressed the minerals I faced the convergence problem and I get the following error. -- Can't converge, abandoning path. -- Xi step is too small. If I don't use the suppress option there will be no problem and I can use " Pickup->system->entire".

Try reinstalling the program to fix this problem. The program can’t find the Microsoft Visual C++ redistributable. Please try running the GWB installer "as administrator". Or, try temporarily, disabling antivirus software while you run the installer.
