I have a confusion which is to get the data of particles when I use matlab linking with comsol. But the function of mpheval is error.
For instance, qx=mpheval(model,{'qx'},'dataset','part1','t',0);
Unfortunately, there is
Error using mpheval (line 234)
Java exception occurred:
Exception:
com.comsol.nativejni.FlNativeException: Failed to evaluate expression
(rethrown as com.comsol.util.exceptions.FlException)

Have anybody help me, please.

The best way of proceeding is to upgrade to V4.3b where a new function mphparticle has been added. This is the most convenient way of evaluating particle data. See the release notes for more information:
