Dear All,
please help me regarding mphinterp function.....
while using,
coordinate=[29970,10080]'
'' electric_field=mphinterp(model,'(es.Ey*es.ny)','coord',coordinate)''
in comsol 5.0 with matlab, i am always encountered with the error message
Error using mphinterp
mphinterp : Java exception occurred:
Exception:

Hi
es.ny is only defined exactly on a boundary.
I suggest you try something like this:
[x,y,d]=mphinterp(model,{'x' 'y' 'es.Ey*es.ny'},'edim','boundary','selection',3,'coord',0:0.1:1);
and use the 'selection' property to select the boundary you are trying to extract data for.

Hi Asha
You're welcome!
You can also do:
electric_field = mphinterp(model, 'es.Ey*es.ny', 'edim', 'boundary', 'coord', coordinate)
