TUFLOW Message 2019
ERROR 2019 - Reading 2D BC data while allocating memory.
An error occurred reading 2D BC data whilst allocating memory requirements. This would usually mean that the format of the file being read is incorrect (for example, incorrect number or types of attributes in a 2d_bc layer), or the file has been corrupted.
Check the GIS attributes match those described in Table 4.33 2D Boundary Conditions (2d_bc) Attribute Descriptions of TUFLOW manual (Table reference for 2010 version), or in empty file: 2d_bc_empty. If problem still persists try re-exporting file (in case of corruption).
