This mesh was built with LaGriT strategies that capture the resolution at 83 wells and the basalt and watertable interfaces, but also keep the total number of nodes below 500,000. The result captures resolution in important areas along the basalt and well locations - but only coarsely captures features such as the thin basalt arm on the west. This mesh is considered a first draft and new strategies can be used to improve the resolution and the mesh quality.
Mesh issues to address in next versions:
Using old version water table surface wt_surface_ev_WC09.inp update to Aug 12 2011 From directory /scratch/er/monty/lanl/water table/maps/2011-02 cp wl*feb*811*ascii.grd /scratch/er/tam/er_monitoring_2011/watertables/wl_2011_feb_s_tw_20 110811.grd Fix extreme elevation at intersectin of polygon and TB4 surface that creates a false spike and bad ccoefs at elements at that edge. This is caused by TB4 "cliffs" where values past TB4 boundary are very high or very low to represent the null data for the material. The TB4 surface and water table surface should be clean and be coincident in the null area. Negative coupling ccoefs along steeper west slope of water table surface (410 m edges). - Reduce edge length of triangles to 230 - 300 meters to avoid problems in slope area (10 meter from next layer) - Consider adding a layer of nodes above the water table Negative coupling ccoefs at some wells along steep slope because the well object is horizontal and does not form good connections where slopes are steep. Use stack method to add layers to keep well columns (do not use offset) Negative coupling ccoefs along TB4/water table interface caused by wedge shapes in pinchout. - Form a 10 meter high pinchout, blunt edge to TB4. - push TB4 zic down to 10m buffer layer ( wtr - 10 ) - color tets by coarse hex and polygon fence Fix well x,y locations that differ from mysql data - R-53 has 2 different x,y locations 7 meters apart - R-41 and possible others suffer from smoothing that should not have happened. 8 and 24 m radial well pts should have true radial distance - Need automatic way to deal with well objects that overlap such that one well will "win" over the previous and remove points that are too close to winning well - Need automatic or script to buffer vertical well screens and perhaps add 1 meter vertical resolution to pumping well objects What to do with well points that exist very close but not the same as mesh point. - Remove mesh well wheel, add real well wheel? Or remove real well wheel, keep mesh wheel? - What is "too close"? 1 meter? 8 meters? Buffer the Tb4 polygon and remove interface points. - need to create buffer polygons + - about 5 meters - should have strategy or code to coarsen any given polygon to some edge length h
