Hello All,

We are attempting to create an mph model of a TPC (Time Projection Chamber) through a program called 'Eclipse' which compiles java code and creates a 'class' file, which when opened in COMSOL can be saved an an mph file. This method successfully creates the mph file for all geometries we attempt to build with our java code, but when we increase the size of our total geometry past a certain point, computation is unsuccessful within COMSOL. We are able to open the file, but when attempting to compute a study of Electric Field, we receive the error message:

Error in multiphysics compilation.
-Feature: Compile Equations: Stationary (sol1/st1)

This is strange, because all we have done in the java code to go from a computing simulation to one which does not compute and gives us an error, is the changing of a single variable that essentially increases the length of our TPC. Based on the contents of the error log from the terminal during this error, and a screenshot from the Eclipse debugging which I have attached to this post, we suspect that the problem causing this is either:

-A problem with the COMSOL 5.0 Jar files on our machine,
-Some sort of memory issue with Eclipse's compiling of the code. Perhaps this is telling us there will eventually be a memory limit in what can be computed

If anyone could take a look at these error and debug messages to offer ideas, it would be tremendously appreciated.

Thank you.
