Since your system is too complex, I suggest you first using VASP to calculate a simple system such as a water molecule to check whether the ESP over the vdW surface can be normally produced via the aforementioned way.
]]>Hartree potential is different to ESP, it only corresponds to the electrostatic potential due to electron density. In contrast, in the definiton of ESP, the nuclear charge contribution is also taken into account.
So you think I should use the Total electrostatic potential, which also include the XC part ? Because vasp already include the ionic+Hartree in the output file.
]]>Thank you very much for your reply. I am sure there is no problem of charge and potential. CHG.cube is the charge density and POT.cube is the Local Hartree potential from LOCPOT output file. I think the abnormal may comes from the mismatch of VASP and Multiwfn. I will check more carefully.
Thank you again for your suggestion and patience
Dear Lu
I followed your suggestion and check each item for installing multiwfn and it remained the same.
So, I find a new computer with win10 and tried the multiwfn_3.7_dev. And the program collapsed at
0 // Start calculation
ESP.cub // The cube file recording ESP
I do not know what the problem. Can you check what happens?
I updated Multiwfn today, this version is able to normally perform quantitative molecular surface analysis based on your cube file, the resulting map is shown below
If the grid data contained in the POT.cub is ESP, the map seems to be weird. Since I am familiar with VASP, I cannot give you more advice.

]]>Hi
I also tried this method by generation charge density and potential cube file from VASP calculation by files format conversion. And when I followed your suggestion and Multiwfn just stopped at: Loaded CHG.cube successfully! I used the Multiwfn version 3.6 and The cell in my calculation is cubic cell. I also checked the CHG.cube and POT.cube by Vesta and they all show normally. I do not know what happens and can you give me some tips?
I didn't test compatibility with cube file of VASP. Since some codes related to grid data reading has been changed during development of Multiwfn 3.7(dev), I suggest you try 3.7(dev) first, if the latest version is still unable to load your cube file, please upload the cube file to a netdisk and show me link, I will download and try to figure out the reason.
]]>Currently Multiwfn is mainly designed for analyzing isolated system, there is no option that can remove the upper layer. You should manually erase it using image editor.
