FAQs

No, both the Windows and Linux OS versions of each software product are included with each software product web license that you own.

Yes, a valid web license for each Itasca software being used is required.

No, it is about the same speed, although we continue to gather more data on this.

Yes.

Some minor GUI differences (e.g., fonts).
Since different compilers are used for the different OS versions, results from the Linux version may not be exactly the same as results from the Windows version. All models are repeatable in either Linux or Windows. However, when we update or change compilers, model results change due to changes in floating point operations and compiler optimizations. How different? It depends on the type of model. For some models the results can actually diverge due to numerical differences from the compiler. In some cases, the differences in response can be much less than 0.1%.
File names and paths in Linux are case sensitive and should not include spaces. So, be careful when calling data files from other data files.
