  1. Map file causes SMS to crash

    I am having an issue with SMS crashing when trying to open a map file. I am using Version 11.2.2 (64-bit) of SMS. I have an Observation coverage in the Map module with some a few feature arcs and points. Edited the names of the nodes and arcs through attributes. Saved the map file. Then later when attempting to open the map file SMS crashes, prompting to send in bug report. Can you please help? Thanks, Karl
  2. Hello All, Short Version: Am currently trying out the different in SMS included automatic mesh generators. Is there a method which does take polygons, points & 'dangling' arcs and then, given min and max size for vertex length, generates a mesh (if necessary, also interpolates vertices on arcs)? Long version: I'm currently using SMS 10.1.11 to generate a mesh and have a couple of days to compare different ways of generating the mesh. Version: SMS 10.1.11 64bit Objective: Want to generate a mesh from lines given in a resp. several shapefile(s). This includes a closed line around the whole area (polygon) and a combination of 'dangleing' (line starts on some polygon border and ends somewhere inside) and closed (forming sub-polygons) lines (resp. feature arcs, once they are converted to Map Data). The 'classic' way is to dot the lines in GIS and combine it with a background raster of a premediated node distance. It works, but does easily result in 'ugly' structures next to given lines. So I tried the different auto-meshing algorithms SMS offers: - none Only useful in the 'classic' case. - patch Fails with "overlapping elements". Seems to be connected to difficulties in generating the polygons from feature arcs (need to run 'generate polygons' several times to convert all areas). - paving Works, put does not offer the ability to set min or max size of elements. Which results in a rather 'ugly' mesh when run on the given feature arcs. When nodes get uniformly respaced along feature arcs, SMS either generates a mesh of uniformly sized elements (which do get computationally expensive) or crashes. - scalar paving density Does not work unless anything 'dangling' is removed beforehand. Then it does construct rather nice meshes of (a predetermined) variable element-size. - existing nodes not tried, but does not sound useful in this case. Is there an algorithm included in SMS which generates meshes like scalar paving density, but takes into account any 'dangleing' arcs and any given points? Thanks for your help, S. Berendsen
