You can now undock and dock windows while editing a discharge simulation.
Right-click any column of data and select:
Set All Column Widths to change the column widths to fit their data. Fields with long strings are set to a maximum of 300 pixels.
Set Column Widths to Title to reduce the number of lines in each title by one (usually from three lines to two lines), then set each column width to the width of its new title. Changes made on the main window are applied to the edit window and vice versa.
For example, from
right-click in a column of data and click
Set All Column Widths to give:
We have been working hard to make WellSim simpler, faster and easier to use:
The layout of the main menu bar has been complely reorganised.
You can undock many tabs to become independent windows that you can resize and drag on the screen see how.
We have been working on the internals to make WellSim more stable.
Previously, a dotted or dashed graph (with symbols turned off) with many points would display as a solid line. Now it always shows correctly.
In most tables, you can change the sort order temporarily by clicking in the column's title area see how:
Synchronise dependent axes for for quick graph and multiple graph settings
If a graph has two dependent axes, then the axis grids can be confusing, see below left. If you tick
Synchronise dependent axes then the top/right dependent axis uses the same axis grids as the bottom/left dependent axis. The axis grids are simpler. WellSim changes the top/right axis numbers to suit the new grid.
While you are editing and running a discharge simulation, you can now view, edit and save the the well's secondary feedzone data. This speeds up modelling a well's secondary feedzones.
Updated the tutorial to model a well's secondary feedzones see here.
If you change the parameters for a simulation and go to save it before you have rerun the simulation, WellSim gives a warning.
When you change a dataset that is used by a simulation, WellSim displays warnings read more.
For example, if you change a geometery configuration that is used by a discharge simulation, WellSim displays warnings for the discharge simulation by hilighting in orange the discharge simulation data:
Database version is now 13
You can now run WellSim from the command line, using the -b or --batch parameter, to run discharge simulations and output simulations. Specify the required input data in text files and run WellSim from the command line; WellSim writes the results to text files read more.
The advantage of running from the control line is that WellSim will run unattended. You would typically do this from another program, which would write the input files, run WellSim, then read the result files. For example, if you are doing a reservoir simulation using another program you could use this other program to run WellSim from the command line to:
Auto option for delimiting fields, to better manage data with double quotes, commas and carriage return / line feeds. Field delimiting options now include memo, header, other non-numeric and numeric. Read more.
You can save predefined groups of fields to export, and recall them later read how.
For this release of WellSim we have been working on ways to make WellSim simpler, faster and easier to use.
This is to emphasise the fact that the well's primary, deepest feedzone is handled in an output or an injectivity simulation. Therefore:
Well sort shows a wellhead, then the list of wells in the database is sorted by by time (the value of
Well sort to sort by well name.
Well sort shows a clock, then the list of wells in the database is sorted by well name. Click
Well sort to sort by time (the value of
