Hi, I would like to plot the partial density of states in terms of dxy, dxz, dyz, dx2−y2, dz2. Currently, in CASTEP, we can plot PDOS as s, p, d and f orbitals versus energy But, I would like to plot only d-orbital, but in the form of as t2g and eg orbitals (dxy, dxz, dyz, dx2−y2, dz2). Any manual calculations needs to be done using the PDOS we get? If yes, could any one help me please with this. Thank you

Dear MS community, My lab purchased Materials Studio last year in March 2024, and it was successfully installed on our personal workstation. I wanted to know if we can utilize our institute's Supercomputer to run the software without actually installing on it. We just want to use the advanced computing power of the Supercomputer to run our simulations faster. Please let me know the procedure. Regards.

Dear all, I would like to understand how CASTEP in Materials Studio converts the raw band structure data from the output file foo.bands into the format used for plotting the band structure, which can be exported as a CSV file. I am not looking for the script used in this conversion or the plotting itself; rather, I want to understand how to manually perform this conversion. Specifically, I am interested in the step-by-step calculations involved, so that I can verify the first few data points

Hi MS Community, This is regarding calculating Solvation Free Energy (SFE) using Forcite module. So, basically I wanted to calculate SFE of Paracetamol (PCM) in Acetone (and in various other solvents and wanted to corelate it with the experimental values at 303.15K). I made two attempts with Acetone as solvent. Attempt-1: PCM molecules- 1 Acetone- 100 SFE turned out to be -94.295 kcal/mol which is highly unlikely. Now if you apply the formula, Solubility= exp( -SFE / RT) (provided by @TM in one

Hello community, I hope my message finds you well. I am a user of Materials Studio (MS) software, which I use mainly for calculations of adsorption, interactions and dispersion forces. However, I have noticed that the values obtained are abnormally high compared with those reported in similar studies, even though they were carried out using comparable parameters. I would therefore like to test the use of scripts in MS to better understand and identify the source of the problem.

Hello everyone, I recently downloaded the `xLink.pl` crosslinking script and the associated `User Menu Jan4_2017.xml` from this community. I used the `DGEBAx32_13BDx32.xsd` file provided in the `sampleinputs` folder, which is already constructed as an amorphous cell. Here is what I did step by step: 1. Imported the `.xsd` file into Materials Studio 2. Performed Geometry Optimization to stabilize the structure 3. Registered `xLink.pl` and the XML menu in my project (confirmed successful – see

I am currently working on determining the diffusion coefficient of a gas through a clay mineral's nanopore. As a preliminary step, I ran a Sorption module simulation to identify the locations of gas molecules within the pore space. However, the results appear to display a density distribution rather than the spatial distribution of individual gas molecules. I would greatly appreciate your guidance on how to obtain or visualize the molecules in the nanopore instead of just the density output.

Hello there, I’m currently working on DFT calculations using CASTEP, and I was wondering if there is any way to extract the exchange-correlation potential from a CASTEP run. I’m aware that the exchange-correlation energy is printed in the .castep output file, but my interest is in obtaining the exchange-correlation potential itself — either as a numerical grid or any form that could be visualized or post-processed. Is there a way to extract directly or indirectly? Any guidance or

How to determine through COSMO-RS at what molar ratio between HBD and HBA a low eutectic solvent can be formed, and what is the corresponding temperature?

Hello, I have been struggling to connect my MS software job control to a computer cluster to run heavy calculations and save on computational time. So far my problem has been connecting to the license server that is running on my MS computer. I cannot figure out if this is a firewall issue on the computer or on the HPC. It is probably beneficial to note that the MS computer can be pinged from the HPC, indicating that they can interact with each other. I am unsure how to proceed/troubleshoot

Hello there, My apologies if this is not the proper place for this, but my workplace is looking into using the Biovia Draws product and I am needing to see if there is any accessibility information on it, especially a VPAT(Voluntary Product Accessibility Template) of it that I can access and see whether or not the software meets standards. Is anyone aware of accessibility documentation for Biovia?

Dear colleagues, I am a PhD student currently working on modeling charged surfactant systems in MesoCite. The documentation ("Tasks in Mesocite") mentions the option to "use smeared charges," but I would appreciate some clarification on the implementation details. Should the charges be assigned to the beads directly in the Properties Explorer, or is it preferable to define them via the "Types/Interactions" section within the Forcefield Document? In the "Electrostatic Interaction" tab (Forcefield

Hello everyone, I can't find downloading link for materials studio. I have contacted for support for three days and I haven't got replies. I also want to get certification of materials studio. What should I do? Best wishes, Ruixian

It is shown in the previous materials that the summation methods used to calculate the static dielectric parameters are Ewald and Group-based, and they have different calculation formulas respectively. However, GPU acceleration only supports PPPM. Then, whether PPPM supports the calculation of static dielectric parameters should be based on which formula?

Hi, everyone! Apologies if this question isn't very chemistry-related. The salesperson directed me here. I just wanted to ask how I can purchase/obtain the software and license, and if there are any student discounts available. I’ve browsed the website a few times but couldn’t find the information on how to obtain it, so I hope someone here can help.

Greetings, I am using Material Studios to perform DPD simulations on mixtures with several components inside. I calculated the DPD parameters separately and then manually input them in Mesocite "Force-field manager" for cases where I do not have too many beads. However, I am now sutdying a case with severeal dozens of different beads and manually input all the possible bead pair parameters is just unfeasable. Is there any automated tool I could use to speed up the Mesocite force field file

Dear all, How to use the "Unique Bond Lengths and Angles" script in Materials Studio? I have an optimized crystal structure (from CASTEP), say X.xsd. When I run this script it creates a folder in the project explorer with three files: X.xsd, CalcUniqueBondLengthAngles.pl, and CalcUniqueBondLengthAngles.pl.out I can not see any bond lengths and angles of my structure. Any help is much appreciated.

Dear MS Community, I’m working with a molecule whose initial torsion angle is 2.2°. However, when I use the Amorphous Cell module to pack multiple copies of this molecule into a periodic cell, that torsion angle changes. I confirmed this by extracting a single molecule from the .xtd file, and measuring its dihedral. I’ve tried various options, but can’t preserve the 2.2° torsion during packing or the subsequent geometry optimization. My goal is to lock this torsion angle in both the Amorphous

Dear All, Can the Adsorption Locator module in Materials Studio be used to identify the adsorption sites of a polymer for a gas molecule like CO₂? If so, is it sufficient to use a single polymer chain in the model, or is it necessary to include multiple chains (e.g., an amorphous cell) to obtain meaningful adsorption site information?. Thanks Hakkim

Hi everyone, When we open a COSMO file of a macromolecule, such as a polymer (which it is represented as an oligomer with a limited number of monomer units) in COSMOtherm——should we add information under the polymer properties section from pure compound properties? If so, should properties like density, molecular weight, molar volume, etc., be based on the actual polymer rather than the oligomer used in the simulation?

I recently installed Materials Studio and it has never worked properly. I can open the software and it mostly works, but I am unable to select atoms by clicking on them or by using the selection box (click + drag). I have tried every different display style (for ball and stick it will select something that's not the atom I clicked, for the other styles I can't select by clicking at all), and I toggled the 3 checkboxes under tools-options-graphics with no luck. I have tried restarting the program

Hi, When I use the SLE phase diagram in Cosmotherm, it requires me to input the diffusion energy of my molecule. How can I calculate this energy when my molecule is actually an oligomer representing a polymer?
