'Old' interpolation file?

Matt Frain

I have written a number of interpolation files for a transient species calculation. I wrote these files in lieu of data files because I was looking at transient species dispersion in an essentially frozen flow field, I just needed the transient species data.

I am attempting to read back these files. I get the following error for a number of the files:

Error: The interpolation file is old, you need to generate a new file. Error Object: #f

Can anyone make sense of this?

Thanks.
