error message when define interpolating function in matlab (other function types work, in comsol it works as well)

Hello everybody,

whenever I define an interpolation function in matlab with

model.func.create('int1', 'Interpolation');

I get an error message (see below) - but if I write instead "model.func.create('ana1','Analytic');" or the same with 'MATLAB', the problem does not occur. Using the COMSOL interface directly, it works fine (it is just the exported model from comsol that I try to solve via the skript instead).

Does anyone have the same problem? This weird problems popping up drive me crazy :(

All best :)
Sabine

ok, problem is solved -- when I tell matlab/comsol what to interpolate

(i.e.
model.func('int1').name('Interpolation surface var0');
model.func('int1').set('nargs', '2');
model.func('int1').set('funcs', {'funcsurfcp0' '1'; 'funcsurfcn0' '2'; 'funcsurfU0' '3'});
model.func('int1').set('source', 'file');
model.func('int1').set('filename', '/users/me/datasurfacevar0.txt');
model.func('int1').set('defvars', true);
model.func('int1').set('nargs', '2');
)

BEFORE I run the solver, it works. (Or first run the solver and then create the function, of course.)
I keep this post in case someone else comes across this error message..
happy modelling :p
