[Mesa-users] What could we do and how to interprete data from profileN.data ?

[Francis Timmes]

hi agung,

each row in a profile corresponds to one cell in a model.
if a model has 200 cells, then the profile will have 200 rows.
each row can be arbitrarily long, depending on the output requested.

i doubt the model has 39,000 cells. perhaps your editor/viewer is
set to wrap lines that are longer then the viewport width. if so,
then the profile may appear to have more rows than it actually does.

yes, a point in time.

> how could that one condition again have 39000++ rows ?

because the model has many cells, each row with many variables, for that one timepoint.

clearer?
