Recently I've bumped into an issue with Crayfish being unable to load large XMDF result files. When result files exceed some unknown threshold of either number of cells or file size, the Crayfish plugin is unable to load the file. I've spoken to the good people at Lutra Consulting who developed the plugin and while they are aware of the issue, the plugin has taken on a life of its own and they can't continue to maintain and trouble-shoot it for everyone. This got me wondering: 1. Has anyone else come across this issue? If so, what have you found out about the limits and possible solutions / work-arounds? 2. Would there be interest from other users in pulling together a consortium to co-fund support and development of Crayfish into the future? Alternatively, a consortium could be assembled to fund the resolution of this specific issue only. 3. Are there plans for TUFLOW to expand their current QGIS plugin to offer more of the functionality of Crayfish? If not, would there be interest in leading and supporting a consortium? ds.
An issue has been identified in the 32-bit versions of the 2016 TUFLOW release when using the XMDF output format. This may cause the simulation window to disappear unexpectedly, with the final lines in the .tlf file looking something like the below: Found 0 User Defined Output Zone(s) Found 1 2D domain(s) This appears to be due to an issue in the external xmdf libraries used by TUFLOW. We are looking into this and will address this with the first update to the 2016 version of TUFLOW. In the meantime, simply specifying DAT format instead of XMDF, will allow the model to run (all other output types, such as asc, flt, wrr, wrb, wrc, nc, tgo, tmo) are not affected. Map output format == dat The res_to_res utility can be used to post-process dat files into xmdf format if required. Please see here, for instructions: http://wiki.tuflow.com/index.php?title=RES_to_RES#Convert Please note, this issue does not affect the 64-bit versions (which the vast majority of people use).
