[ncl-talk] Plotting unstructured mesh

[Mathieu Dutour]

Dear ncl users,

I have some errors for some contour plots on unstructured
grids (the script is in attachment and the relevant netcdf file
is available from
http://mathieudutour.altervista.org/Sending/test.nc   )

Below is exact error:
fatal:ContourPlotPreDraw: ARSCAM/ARPRAM - ALGORITHM FAILURE
fatal:ContourPlotDraw: draw error
fatal:PlotManagerPreDraw: error in plot pre-draw
fatal:_NhlPlotManagerDraw: PreDraw error

I believe that the data is too irregular for the algorithm to plot it.
But is there any way to alleviate this problem?

Secondly, the plots sometime takes extremely long time to be done.
The mesh has only 110804 nodes which is nowhere near big. What
would be possible to avoid that problem?

  Mathieu
