Hi Swarnadhar

Your script that contains calls to flclear, fem.const etc. are older than Comsol version 4.0, which was released in 2010. The commands for using Matlab with Comsol changed at that time. You can't use the old script anymore.

I suggest that you recreate the model using the Comsol user interface using a modern version of Comsol. Once you have done that you can use LiveLink for Matlab to automate the interaction between Comsol and Matlab.

I your screenshots I also see error messages related to general Matlab errors. You need to inspect your scripts for proper naming of variables etc.
