Is it a COMSOL Bug?

Please login with a confirmed email address before reporting spam

Dear COMSOLers

Recently, I encounter a very weird question about COMSOL 4.0a.

I just open Try.mph in COMSOL desktop and COMSOL with Matalb, and then export it to COMSOL server, then open the Try.m in the Matlab and press F5 to run it.

Try.m is like this:

% Import model form the COMSOL server
model = ModelUtil.model('Model');
for k = 1: 60
disp(k);
tic;
model.sol('sol1').runAll;
toc;
end

I just use the "tic" and "toc" to test the time consumed in each sweep.

The weird things happens!

As you see in the figures in the attached files, when k<33 , the time consumed is nearly same, about 13 seconds.(fig1.jpg, fig2.jpg). But when k> 34, the time consumed in each sweep increased significantly(fig2.jpg, fig3.jpg). when k = 55, it almost takes 199 seconds for one sweep(So weird). and After it, the sweep for k=56 stoped without any error message, but the comsolserver CPU is 0%(fig4.jpg).

I'm so confused about this. I donot know if this is a COMSOL bug. How can I figure it out?

Best wishes!

Kyo
