This is a test area with new WindSim versions, utilities and extensions. For a list of new features consult; Fixes and extensions. Your feedback on the use of these applications will be appreciated. Please consult; Known bugs and shortcomings and FAQ.
Beta programs will only work on PCs where a WindSim full edition is already installed. Administrative privileges are required during installation.
Old beta programs can no longer be downloaded when newer versions are available, or when they have become part of an official WindSim version. The upgrade history is kept as documentation of the development.

| Description pages on blocking and refinement. | ||
|
||
| Folder for the power curves has been reset. In the previous beta the folder was incorrect, consequently new power curves could not be added to a project. | ||

| WindSim 4.7.0 Beta 070402 (45.0 Mb) | 02.04.2007 | |
| Restrictions on the model size intended for a free demo version was inserted in the 32-bit version, these restrictions have been removed. | ||

| When applying nesting, the coarse model must be based on a regular grid, whereas the fine model could be based on either a regular or refined grid. | ||
|
||
| Smoothing of sub-areas can be performed with the tool Convert terrain model. | ||
|
||
| WindSim 4.6.0 Beta 060402 (34.0 Mb) | 02.04.2006 | |
| A new output file with data from a cube around each hub will be created in the module Energy when "Export vertical profiles" is activated. | ||
|
||
| If a simulation was interrupted in "Wind Fields" by pressing the Stop button, the process earexe which was running in background mode was not killed. This has been fixed. | ||
|
||
| WindSim 4.6.0 Beta 060328 (34.0 Mb) | 28.03.2006 | |
| The WAsP .rsf export has been unstable, this has been fixed. The export of the .wrg format is included. | ||
|
||
| WindSim 4.6.0 Beta 060326 (34.0 Mb) | 26.03.2006 | |
| In connection with the upgrade to a newer PHOENICS version, the nesting failed due to a new PHOENICS format. This failure has been fixed. | ||
|
||
| A new output file with data from a cube around each hub was activated in the module Energy before fully tested. This could lead to run-time errors if the model has a coarse grid towards the ground or if the hub heights are too low. The new output is deactivated and will be included again when limiting cases can be handled. | ||

| WindSim 4.5.0 Beta 050901 (37.0 Mb) | 01.09.2005 | |
| Made the WindSim project folder drive independent. The project folder is chosen during installation, the default folder is C:\WindSim AS\WindSim Data. The project folder can be changed in the file C:\WindSim AS\WindSim4.5\Environment.xml | ||
|
||
| Failure in setting the terrain extension in Terrain after changing the grid.gws has been fixed. | ||
|
||
| If Terrain is re-ran the wind database is removed. In this case the reports should be removed and the property grids should be re-set. Failure in connection with this removal and resetting is fixed. | ||

The new version of the Tools - Convert terrain model includes conversion of WAsP .map format to WindSim .gws format. The .map format contains both height and roughness data as contour lines, here is an example of a valid .map file; demo_map.zip (1.3 Mb). The tool is included in the WindSim 4.5 version.
After downloading and unzipping the below file dtm_conversion.zip, place dtm_conversion.exe in the WindSim program folder, which for a default 4.m.n installation will be; C:\WindSim AS\WindSim4.m\WindSim_4mn. Take a backup of the existing dtm_conversion.exe by copying it to e.g. dtm_conversion_old.exe.

| dtm_conversion.zip (0.4 Mb) | 11.03.2005 | |||
| Made conversion tool version independent. The conversion tool can bevexecuted as a part of all post 4.4.1 versions of WindSim. | ||||

| dtm_conversion.zip (0.4 Mb) | 07.03.2005 | |||
| Possibility for adding nodes when the discretization of the contours is too coarse. Large variation in the distance between adjacent nodes in the contours could be misinterpreted by the interpolation algorithm. An automatic addition of nodes will prevent this misinterpretation. | ||||
|
||||
| Improved reading capability by accepting contour data stored pair wise per record (x1,y1), in addition to the default storing of triplets per record (x1,y1,x2,y2,x3,y3). | ||||

The default pre WindSim 4.3 setting allows simulations of models with approximately 400 000 nodes. In the below version the array limit is increased. We have run successfully a model with 700 000 nodes on a 512 Mb RAM PC. The limit on the maximum number of nodes in each direction is 250x250x40 in the x, y and z direction respectively in pre 4.3 version. In version 4.4 this limits were increased to 400x400x40. Associated satexe and earexe with increased array limits is given in satexe_xxl.exe and earexe_xxl.exe, with these limits we have run successfully model in the order of 3 000 000 nodes.
After downloading and unzipping the below file(s), it must placed in the WindSim program folder, which for a default 4.m.n installation will be; C:\VECTOR\WindSim4.m\WindSim_4mn. The file must be moved to earexe.exe (or satexe.exe). Take a backup of the existing earexe.exe (or satexe.exe) by copying it to e.g. earexe_small.exe (or satexe_small.exe). From version 4.3.3 the earexe_large.exe is included in the installation.
