Overflow error

[jacksonlord]

I'm trying to run the calculation on a very large resource grid (950,000 nodes) using a pretty detailed contour vector map. When I click calculate, it says that it cannot do the calculation, and that the system reported that: "Overflow".

What is this error?

Off the top of my head, I guess that the program is failing to allocate enough memory to handle the results set which would be calculated.

This is an huge grid you've defined. Are you hoping to use it in WindFarmer?

For now I suggest that you try splitting the grid into four. You will also get some significant calculation time savings by cutting a different map for each sub-grid.

Hope that helps, Duncan.

Thanks for the tip. It is a particularly large grid. I was hoping to use it in openWind.

I decreased the cell size and ran it successfully. Then I successively decreased the cell size by half and re-ran the model until the resolution was satisfactory.
