The Regular Grid component

Testing OpenMI-compliant components is not an easy task. In order to test such components you need to link your component to another compliant component and check that your component is exchanging data correctly. This gets even more complicated if your model also supports geo-referenced element sets. The Regular Grid component was developed with the purpose of facilitating testing of OpenMI-compliant components that provide or accept data represented on polygons.

The Regular Grid component is made as simple as possible. All input is provided through the OMI file arguments and the output is a simple text file. The grid is defined simply as the number of cells in the x- and y-directions, cell size, co-ordinates of the lower left grid corner, and grid angle. The values provided are either constant or linearly increasing in space and/or time. On the figure below you can see an example of the Regular Grid OMI file and the output file
