New Features/Improvements:
Two-dimensional connection plots are now available for TOUGHREACT v3/4 simulations.
The TOUGHREACT CSV Convertor has been updated to correctly populate the INDEX field in mesh and react CSV files.
The Element Name is now included in the XYZ file created using the File | Write Cell Data tool. This allows the user to more easily identify elements associate with wells or other features where the elements have been assigned a name.
A Cell-based TecPlot ASCII file export is now available through the 3D Results window. The .TEC files, including data for each time step, are created for rectangular and polygonal meshes.
A Vector-based TecPlot ASCII file export is now available through the 3D Results window. This feature is supported from Rectangular Meshes only, and includes X,Y, and Z flow components.
Negative values are now allowed for MCYC (under Solution Controls). A negative MCYC value can be used in TOUGH3 to specify a maximum number of time steps greater than 9999. If a value of -20 is entered, TOUGH3 will allow 2^20-time steps (1,048,576). A negative MCYC value should only be used with TOUGH3. This will cause an error for TOUGH2 simulations.
