[Anuga-user] 'MemoryError' about anuga

[Sylla Z. <zby...@gm...>]

Hi, I want to use anuga in a large and complex terrain situation, following
is the statistics:

*Input vertices: 4459*
*  Input segments: 4459*
*  Input holes: 0*
*
*
*  Mesh vertices: 430357*
*  Mesh triangles: 858416*
*  Mesh edges: 1288772*
*  Mesh exterior boundary edges: 2296*
*  Mesh interior boundary edges: 5122*
*  Mesh subsegments (constrained edges): 7418*

Then, I encounter 'MemoryError' as follows:

*FitInterpolate: Building quad tree*
*Building smoothing matrix*
*

May someone help me? Thanks!
