<div style="line-height:1.7;color:#000000;font-size:14px;font-family:arial"> Dear XCrySDen developer and users:<br>Hello.<br>I am using XCrySDen for the charge density or |psi|^2 visulasition of Quantum-ESPRESSO. SInce only one plane can be generated by pp.x in one time, I always draw the figure with single DATAGRID.<br>However, I found some person used CASTEP+Materials Studio to produce the model with two charge density planes which are not orthogonal. Therefore, I also wondering whether XCrySDen can draw the similar model.<br>I tried to generate two xsf files corresponding to different planes by pp.x, and accumulated them by:<br><span style="color: rgb(0, 0, 255); font-style: italic;"><span style="color: rgb(0, 0, 255);"> BEGIN_BLOCK_DATAGRID_2D</span><br><span style="color: rgb(0, 0, 255);"> name</span><br><span style="color: rgb(0, 0, 255);"> DATAGRID_2D_1</span><br><span style="color: rgb(0, 0, 255);"> nx ny</span><br><span style="color: rgb(0, 0, 255);"> x0(1) x0(2) x0(3)</span><br><span style="color: rgb(0, 0, 255);"> e1(1) e1(2) e1(3)</span><br><span style="color: rgb(0, 0, 255);"> e2(1) e2(2) e2(3)</span><br><span style="color: rgb(0, 0, 255);"> FFT Data Mesh</span><br><span style="color: rgb(0, 0, 255);"> END_DATAGRID_2D</span><br><span style="color: rgb(0, 0, 255);"> DATAGRID_2D_1</span><br><span style="color: rgb(0, 0, 255);"> nx ny</span><br><span style="color: rgb(0, 0, 255);"> x0(1) x0(2) x0(3)</span><br><span style="color: rgb(0, 0, 255);">
v1(1) v1(2) v1(3)</span><br><span style="color: rgb(0, 0, 255);">
v2(1) v2(2) v2(3)</span><br><span style="color: rgb(0, 0, 255);"> FFT Data Mesh</span><br><span style="color: rgb(0, 0, 255);"> END_DATAGRID_2D</span><br><span style="color: rgb(0, 0, 255);">END_BLOCK_DATAGRID_2D</span></span><br>But finally I found that not only the nx and ny have to be the same, but also the planes in two DATAGRID should be same. Then I tried to write tow BLOCK_DATAGRID_2D, but when I imported DATAGRID to my model, I had to choose one and only one.<br>So, now I just want to know, are there any methods to get two nonorthogonal plane to show charge density by XCrySDen?<br>Thanks.<br><div>--<br>GAO Zhe<br>CMC Lab, Materials Science & Engineering Department,<br>Seoul National University, South Korea<br>
