plotmodel data

rcstout

Hi, I'm just getting started on ISSM, and am running the Square Ice Shelf tutorial. In plotmodel(md,'data',md.results.StressbalanceSolution.Vel), I'm confused about where the data is coming from, since md.results.StressbalanceSolution.Vel is a 91x1 double (not a matrix), but the plotmodel function produces a contour plot. I've looked through the documentation and the code for plotmodel and plotmanager, but am still confused. Any help in interpreting the model results structure would be appreciated!

Thanks!

rcstout I think that the vector (91*1) vel have a coresponding sequence in finite element mesh. That means every value in md.results.StressbalanceSolution.Vel is arranged to special mesh grid. It may be save compute time?

Thanks for the quick reply! Where should I look to figure out how the values stored in results are mapped to the mesh grid (and to the contour plot that plotmodel produces)?

Hi guys, yes the size is what matters for plotmodel. If the size of the vector is the same as md.mesh.numberofvertices, plotmodel knows that each value in the vector corresponds to vertices in the mesh. If it is of length md.mesh.numberofelements, plotmodel will know it is an element vector, etc. You can take a look at plot_unit.m and processdata.m.
