Can somebody please shed some light on this error?
Firstly model is exported from COMSOL (both 4.4 and 5) as .m file.
The I start matlab using the command: comsol mphserver matlab
and try to run the .m file exported from comsol getting the error below.
Error using model_name (line 402)
Java exception occurred:
