Has anyone ever come across the following message when trying to compute 2D flow area tables in HEC-RAS 5.0.4? Error computing 2D Flow area tables: Array dimensions exceed supported range.
I am running HEC-RAS 5.0.4 on Windows 7 with a 64-Bit operating system. The model in question has just under 500k cells. I am able to calculate the 2D flow area tables without any problems in version 5.0.3. If anyone else has come across this issue before and figured out a workaround please let me know.
That looks like an error I was getting when importing a terrain in 5.0.3. It turns out when I exported the elevation TIFF from ArcGIS, the default value for areas with no data was an obscenely large number, -1.797693e+308. I changed the no data value to something smaller, -999, and had no more problems with the terrain.
