Problems while converting M-files in comsol 3.5a to comsol 4.0a

Hello,

When I tried to convert M-files from COMSOL 3.5a to COMSOL 4.0a, the syntax is entirely changed since the new code is model object method.But I cannot edit the variables in the new program because it creates some binary files (.mphbin files). So is there any way to use the new M-file more effectively, in a way without generating this binary files so that I can edit it easily. Otherwise I need to rewrite all the codings. Expecting a quick reply.

Thanks & Regards
Noel

Hi

for me the nphbin were also often created in 3.5 if you hit the file>reset model. and then I gave up to get back the solids as individual parts (you can still load them in and use them or add items to them)

In general I study the way V4 translates V3.5 files, but I always restart m models from scratch in V4. And I agree I have still to learn (again) the new syntax of the new V4 matlab I/F (and my clients are not paying me for that, unfortunately that seems to be the price to pay for most software today ;(

Good luck

Hello

So it means the best way is to program it again ?
I already started programming with the new syntaxes and it works well for me. The new syntax is more Java based but the help files are pretty good enough to program it in V4.
Thanks
