mphglobal with Matlab returning multiple values

Hi there,
I was using mphglobal successfully to pull parameters from my comsol model but now I have an issue. I made some changes to my model such as changing the mesh and adding some more variables and now when I try to pull out parameters with mphglobal it will return the value 41 times. So instead of returning a double, it returns a 41x1 array of identical doubles. Any idea what is going on?

Thanks,
Bryan

Hi

If you have a time dependent model or a model that has a parametric sweep your global variables can take different values for different times/parameter values. I assume that is the case for your model.

You can use the function mphsolinfo to get information about the number of steps in your solutions.
