<div>Dear Developers and Users,</div>
<div><br>
</div>
<div>I need some advice on using the 3ddens program. My interest is to <span>simulate STM image of a 3D system to compare with our experimental results.</span></div>
<div><span></span>My questions are: <br>
</div>
<div><br>
</div>
<div>Whether it's possible for 3D system.</div>
<div>What determine the size of the grid points?</div>
<div>Do I have to edit any file in my case directory before x 3ddens -XX?</div>
<div><br>
</div>
<div>I want to test run using TiC, what are the general tips? Any hint is highly appreciated.</div>
<div><br>
</div>
<div>Thanks a lot for your time.</div>
<div><br>
</div>
<div>With kind regards.<br>
