open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello, I'm using the Telemac python scripts to read and manipulate a results file. I would like to modify some wave directions and then save to a new output.slf, however I am having some difficulties. I use out.fole.update({ 'hook': open(outFile,'wb') }) to create my new file, then after creating the header, I try to add the results data using out.appendCoreVarsSLF(data) but I get the error

f.write(pack('>i',4*self.NPOIN3))
AttributeError: 'dict' object has no attribute 'write'

I am relatively new to python and so do not really understand this error. Could anyone offer some advice?

Thanks, Oliver

Hello,

Can you share your entire script so I can have a try at debugging ?

Thank you,
Sébastien.

Hi, yes here you go.

Thanks, Oliver

Hello,

here attached with a few modifications and running about 5000 times faster on a small mesh ... main points are:

- not sure what "data" was
- use the slf to read and write instead of creating a new out
- use the power of numpy for array calculations

Hope this helps,
Sébastien.

Hello, thank you for your reply and very useful python tips for numpy array calculations! 'Data' was just a variation on the wave data I was trying to write, not defined as I sent the code whilst making some changes. Appologies for that.

With regards to using slf to read and write instead of creating a new out, I get an error AttributeError: SELAFIN instance has no attribute 'fole' when trying slf.fole.update({ 'hook': open(outFile,'wb') }). I am able to complete the .fole commands when creating a new out but then I get the error AttributeError: 'dict' object has no attribute 'write' when trying to use the .append commands. Am I missing something?

Many thanks

Oliver

hummm.

It looks like the TELEMAC python scripts you have do not have the latest developments. These are substantial.

So -- two options:
- Are you a member of the consortium ? (in which case yo can access the branch guppy)
- If not let me know, I may have to do an intermediate release, which I will have to get authorised by the consortium.

Sébastien.

Hello, I'm not a member of the consortium unfortunately. An intermediate release of these updated scripts would be very useful, if it is possible!

Thanks, Oliver
