hello community. I have a big trouble dealing with a mesh.

Let me explain the case. I am modelling a small river of approximately 800 meters of longitudinal path.

I produce a .2dm mesh by mean QGIS-BaseMesh, using a max area of 1.732 m2 trying to produce a 2 meters delta x mesh. The result of this process is successful and you can look the result in the image attached.

The problem appears when I import the .2dm into BlueKenue and basically the mesh in the 2d viewer looks a quite distorted and I don't know why.

The shapefiles used to build the mesh in QGIS are in CRS projected in the zone corresponding to Ecuador. I have always worked in that way without problems.

Could someone please help me with this giving me an idea to fixed or understand what is happening?

Best regards

Serrer OFFLINE Moderator Posts: 720 Thank you received: 304	Hi Sandoval, This is likely as a result of an OpenGL floating point truncation problem that was addressed in January 2017, BlueKenue Version 3.8.4. Try using the latest version. If your problem persists please let us know. Hope this helps... Martin
