Slice Plot: Post Processing

Hi,
I'm trying to make a slice plot for a self-defined global variable that is a function of a self-defined subdomain variable k and the COMSOL variable T. I'm running this program as an m-file. Presumably, one can simply change the variable name in the postplot code from the default of T to the variable in question. However, when I do this, it created the figure with the geometry but does not produce the color contrast and matlab says it's busy and locks up. Any ideas on how I can fix this or perhaps a better way to make a color slice plot?

Hi
I can only come with some potential clues, inside COMSOL, variables defined i.e. on avolume are progagated to the boundaries "by heritage", as well as the system has derivatives calculated. That is why you should also when possible ensure that the derivativesm of the variables are explicitely available (as far as possible).
Then depending on the plot requested these extra information (such as derivatives) might be used to create the plot. So if your variable is not explicitely defined on boundaries or edges, try to AVOID asking COMSOL to plot edges or boundary values.
Next on the list is the interpolation, try to use linear, and even "wiremesh" as least first to check the values
Now you might have a completely different issue in your case, but the aboves would be my first check
Another test, before plotting try to get the reslts as matrices and number and check if they are coherent
Hope it helps
Good luck
