Comsol scripting error

Please login with a confirmed email address before reporting spam

Good evening

I am trying to script my model. It's basically a piezoelectric cantilever with connected an external load resistor through the SPICE circuit component. I want to see what happens as a function of the load resistor value.

What I did was tweaking the history m-file adding a for loop changing the resistor value.

When I try to run it I get the following error:

--- quote ---
Error in ==> resistorscantest at 44
g400=flbinary('g400','draw',flbinaryfile);
--- end quote ----

Indeed once the history file is saved, on top of it it's written:

--- quote ---
% Some geometry objects are stored in a separate file.
% The name of this file is given by the variable 'flbinaryfile'.
--- end quote ----

But the flbinaryfile is not defined:

--- quote ---
flbinaryfile='';
--- end quote ----

And indeed no other files than the original model file and its history file are present in the folder. I tried to modify manually that line inserting the model mph file name but it doesn't work.


Am I doing some mistake?

Hi

it might be tat COMSOL has put the mphbin in its "default" directory the COMSOL installation root folder. Otherwise my workaround in such situations is to save the geoemtry from te COMSOL GUI, and correct the matlab file to point to the correct filename

Good luck

Hello,

I manually exported the geometry and edit the .m file accordingly and it worked. Now I can continue debugging...


Many thanks
