Hi all,
I would like to be able to change one parameter of my model inside of a for loop with LiveLink and then run the model. Does anyone know how to do this? My code looks something like this:
for CED=[1.0:0.01:3.0] model.param.set('C_ED', 'CED[mm]'); model.param.set('C_EP', '1[mm]'); model.param.set('C_EW', '0.5[mm]'); model.param.set('d_ci', '0.5[mm]'); model.param.set('d_nb', '0.4[mm]'); model.sol('sol1').runAll [b1,b2,b3,b4]=graphingfun(model); end
Thanks in advance!

Hi John,
Why not using an auxiliary sweep?
If the above does not suit you, can you tell us how is the code you submitted not matching your expectations? I am using the java API rather than a LiveLink, so the syntax is slightly different, but from what I can read your code seems fine.

Hi John
When you do
model.param.set('C_ED', 'CED[mm]');
Then the parameter 'C_ED' is set to the expression 'CED[mm]'. This doesn't transfer the value of the variable CED to Comsol. You need to do this instead:
model.param.set('C_ED', [num2str(CED) '[mm]']);
