Hello everyone,
I have been computing several material properties from DFT calculations as shown below in my input file. I have attempted this on v7 and v7.0.2 but both have troubles computing the electron density on this structure and several others. They are able to output the electrostatic potential which is the previous task. When I increase the number of grid points it is successful. I can make a larger grid work but had set the size to report values every 0.1 Ã… and have completed quite a few calculations so would be best if I can get these to be the same.
The error message I am receiving states:
------------------------------------------------------------------------
