Hi I am Rupesh kumar, M.tech student , IIT Delhi. while doing my thesis work under prof. Samaresh Das, i need to plot cv characteristics for my structure. For the reference i have referred on of the exapmle given on Ansys portal ----> https://support.lumerical.com/hc/en-us/articles/360042328674. Upon running the .ldev i got charge chrage.mat file stored in same location in which file is saved and then running the PN_phase_shifter_CHARGE.lsf file i am getting this error ----->  Can not find result 'total_charge' in the result provider 'CHARGE::monitor_charge' .

kindly help me out with it

I guess you are using the old version of CHARGE, as I tested it works fine:

Please install the latest version and test again.

This is a different issue. Usually if you do not open matlab file, but just export data, it does not need matlab to be connected. Please try to test
xyz=1;
matlabsave("test1.mat",xyz);
to see if it works.
For matlab connection, please refer this post https://forum.ansys.com/discussion/comment/140905#Comment_140905
