Hi everyone,

we have a computer, recently upgraded from 4.0a -> 4.1 , where we have a strange problem:

When using some API command (under Matlab) there are systematically error occuring.

When we are running a .m file exported via 4.0a, there is no error in execution.
The same model's .m file exported via 4.1.0.185 -> error occur.


Here is an example:
________________
[...]
model.geom('geom1').feature.create('blk1', 'Block');
model.geom('geom1').runAll;
model.geom('geom1').edgeParamRange(5)
__________________

Here, the error will occur at the last command, returning the following:

__________________

Hi

even if you will not like it, my advise is to redo everything in afresh new v4.1 and not try the direct translation. There are a few variable names that have changed (from my understanding), when you import the fle, these might remain in the "old naming", this is difficult to identify, then you can miss items, or forget some contributions

Another permanant issue is the version matching versions between programmes that are talking to each other via dll or other I/F means, be it CAD, COMSOL, Matlab or even Office and OS.
I always try to keep a logical level between these programmes (which costs me a lot in cash and is difficult to justify for the ROI, but gains me time with error and compatibility issues, while losses my time lerning the subtile changes that the programmers mean are usefull between the versions (a delicat balance to perform)

Sorry I do not have any better advice :(

Good luck
