Starting data: level curves in DXF format and a simple model of dam.gid.zip of a double curvature dam , created previously with GiD
Files->Import->DXF
and select the file 'file topography.dxf'
Lines imported from dxf
Create an auxiliary mesh to have nodes to calculate an approximated raster to represent the terrain surface
...
and select the file 'dam.gid'
Zoom near the dam
Now the dam is overlapped with the terrain, for the simulation we need to calculate the intersection with the topography.
