I have a time dependent heat transfer problem in which a boundary condition is a time-dependent temperature. I have the values in a spreadsheet as columns (two columns: time-temperature). I'm dealing with more than 1000 time values (i.e. 2 columns, more than 1000 rows). I tried to convert them in a table format (attached), but without success. What am I doing wrong?
I'm uploading a simlified version of the pde file, the original data columns and the converted data into table form.
application/octet-stream.PDE file
HT.pde (0.6 k)
text/plainoriginal data
Originaldata.prn (21.0 k)
text/plaintable?
Table.txt (13.4 k)

Your problem is that you have entered the number of data points twice. The extra number gets read as a data value and FlexPDE complains that there are too many points.

You don't need to specify the number of data points in the data section, only in the coordinate section.
For example:

{t coordinate with 1000 data points}
t 1000
1 2 3 4 5 ...
data
1 2 3 4 5 ...

See "TABLE File format" in the Help index.
