How to construct a crowdion defect in BCC Mo?
I am working with a BCC molybdenum supercell (54 atoms) and trying to model a self-interstitial atom (SIA), specifically a ⟨111⟩ crowdion configuration. I want to add extra atom into supercell but in 111 direction. I understand that a crowdion is not a single interstitial atom but a collective displacement of atoms along the ⟨111⟩ direction. However, I am facing confusion in: How to correctly construct a physically valid crowdion structure (without atom overlap) in a BCC Mo lattice Whether the

DMol³ treating deuterium as hydrogen in frequency calculation
Dear Material Studio Community, I would like to ask about deuterium simulations using DMol³ in Material Studio 7.0. As I understand it, geometry optimization and single-point energy calculations in DFT cannot distinguish between hydrogen (H) and deuterium (D). Within the Born–Oppenheimer approximation, nuclei are treated as fixed point charges, and electronic energies depend only on nuclear charge and geometry. Since H and D have identical nuclear charges and electronic structures, their

MS Electrolyte-relate
Hello Dear teachers I would like to calculate the percentage of each solvation structure in the solvation sheath of the electrolyte in MS. I hope that you, dear teachers, can provide some relevant perl scripts. I would like to thank all the teachers in advance for their help and generosity.
P1 to symmetry
Hello every one Please, I would like your guidance. When performing my calculations for electronic band structures, I made my structure P1 while doping it with another molecule. I would like to have the symmetry (not P1) after the geometry optimization. How is it possible to convert a P1 to a symmetry (or to apply symmetry) during geometry optimization? Is there any workflow (any Module is okay) or recommandation I can get from you? To be more clear, this is what I did: 1; Downloaded a cif
Polymer Crosslinking Script xLink.pl
July 25 2025 Here is a zip file of the latest polymer crosslinking script, along with some documentation and examples. That latest update is dated July 25, 2025 (see line 13 of the script). The main update is better support for PPPM. Dec 3 2025 Here is the latest update to the script dated Dec 3 2025: It includes support for chloride condensation reactions (via CustomChem) and fixes a bug that was erroneously producing "coordination mismatch" warnings. In the new Runs folder, I have also
How can I draw a structural formula showing multiple crystals synthesized together in proportion and calculate its bandgap?
I will now calculate the bandgap for a crystal. My idea is to expand the existing crystal structure (since the crystal structures I want to draw are quite similar) and replace the desired elements. I'm unsure if this approach is feasible. The first image shows the structure without element modifications, while the second image shows the structure after element modifications.
Difficulties Incorporating Choline Chloride and Betaine
Fellow Researcher, I am investigating the solubility prediction of binary solute systems in Natural Deep Eutectic Solvents (NADES) using COSMO-RS (COSMO-quick >> solubility prediction). I am facing difficulties incorporating Choline Chloride and Betaine into the simulation. These compounds are missing from the internal database, and attempts to import them via SMILES strings, even manual structure drawing, result in an 'invalid' status (red row notification) during the run. I suspect this
Help Requested on Stress-Strain Simulation
Hello, dear teachers! When using the "make strain get stress" Perl script, I noticed that each applied strain is different, which results in a non-constant strain rate. This leads to a problem: stretching becomes faster and faster or compression becomes slower and slower. Rather than a uniform stretching processCould any teacher help clarify my confusion? Thank you.

Can we also output the corresponding number of frames during the equilibration time when performing molecular dynamics simulations in the GULP module of Materials Studio?
How to design a layer MD model with different solutions on both sides.
#Forcite #Seawater Desalination #Packing #MD Dear everyone, I want to construct a MD model to simulate the seawater desalination. But I find if I use the Packing task in Amorphous Cell. I won't use the Packing function to create a membrane with different solutions on both sides, I can only create a membrane system with a single solution present. I want to replace the solution on the left with a saline solution. How should I do. QAQ

Questions about building a dimer in COSMOtherm using TmoleX
Dear all, I am currently working on constructing a dimer structure for choline chloride (a quaternary ammonium salt), as illustrated in Figure 1. fig 1 the structure of choline chloride. Following advice, I first created an initial guess for the dimer geometry (Figure 2) in order to generate .xyz coordinate files for the choline chloride system. These files are intended to be used as inputs for further
DMol3 geometry optimization: how to relax only the a lattice parameter while fixing b, c, and all angles?
Hello, I performed a DMol3 geometry optimization in Materials Studio. My goal is to fix the lattice parameters b and c, and also fix all lattice angles (α, β, γ), while allowing only the a lattice parameter to change. In the Geometry Optimization settings, I enabled More → Optimize cell, and then ran the calculation. However, in the optimized result, all cell parameters (a, b, c, and angles) were changed, even though I intended to constrain b, c, and the angles. For comparison, I tested the same
