Problem loading large xmdf/sww files #100

Closed saberraz closed 6 years ago

saberraz commented 9 years ago

I have tried to open the result from TUFLOW with .xmdf file(50 GB), but I get some error like I have attached and all of the messages in python error I have show it at below, I don't know it too big file size or not, because for the small file size I can open it:

An error has occured while executing Python code:

Looks like an exception was thrown in c++ code - according to this: https://support.microsoft.com/en-us/kb/185294

Does it work on linux?

Crayfish currently loads the whole content of the file into the memory, so loading a file this big may have run into out-of-memory situation.

Large sww files cause an error in Crayfish (11-24 GB) When trying to open them in crayfish, the attached error message appears: large_sww_file

From Crayfish 3.x release and QGIS 3.4 release, the rendering and styling is implemented in QGIS Core. The data reading and support is implemented in MDAL. Please reopen the ticket in QGIS bug tracker for rendering issues or MDAL for format support issues. Thanks.
