Hi, I am writing to look for the help from experts in this community on the software installation. I just update my system to Win11, and the version is 24H2 which is the only one supported by my university. And before update, I read in the help document suggesting the software only supporting version 23H2 which concerned me so much. Now after installing the software, it report below error: System Error: The code execution cannot proceed because mfc140u.dll was not found. Reinstalling the

Hi， I used MS's Forcite for molecular dynamics simulation, and now I want to count the total number of hydrogen bonds of water molecules in the z-axis direction and the number of hydrogen bonds when oxygen atoms face downwards and upwards. Can someone help me provide a Perl script. Thank you very much !!!

Hi, Can COSMOtherm evaluate relative "conformer" weights of dimers instead of just monomers in a specific solvent? Meaning using a number of cosmo files, each related to a specific dimer, and treat such set of files as a conformer set, similar to what is done for monomers. Are there any additional considerations to take into account for this particular application? Thanks.

Dear all, Hope you all have a good day! While looking into the COMPASS III force field, I found that n2a and n3a have the same description - nitrogen, sp2, aromatic. This seemed strange at first, but on second thought, I guessed that aromaticity requires pi-electrons, which originate from the p-orbitals. Therefore, n2a and n3a share the same description, and the only difference between them is whether the nitrogen forms two or three bonds. Could you please check if my understanding is

I would like to ask whether the forcefields available in the Forcite module of Materials Studio are suitable for molecular dynamics simulations of silicate systems. Here is what I did: I used the Amorphous Cell tool with the COMPASS III forcefield to build a Na₂O–SiO₂ system containing about 500 atoms (O, Na, and Si in the correct ratio). Then I performed a geometry optimization in Forcite using COMPASS III. Next, I ran a dynamics simulation in Forcite (NVT ensemble, 1473 K, time step = 1 fs,

The value of ExternalForceStrength (ranging from 0 to 100) represents the magnitude of the applied external force field. And what does the value of ExternalForceZ (ranging from -100 to 100) represent? Is it a percentage of the ExternalForceStrength value in the Z-direction? In Materials Studio, is it possible to apply an external force within a specific segment along the Z-axis? For example, applying a force of 0.05 kcal/mol/Å in the Z-direction within the region of 50-70 Å?

Dear users, I am currently using the Linux version of MS 2023 together with a perl-script.pl script on our supercomputer server to run molecular dynamics simulations with the Forcite module. I noticed that the 2023 version of Materials Studio supports GPU acceleration for Forcite molecular dynamics. However, I could not find clear information on how to enable or use GPU acceleration in the Linux version. Could you please provide guidance or documentation on how to properly activate GPU

Dear Users, I have performed molecular dynamics (MD) simulations of a polymer–solvent system and need to calculate the fractional free volume (FFV). I calculated the FFV for both the polymer–solvent system and the pure polymer system, obtaining values of 20% and 70%, respectively. The 70% value seems like an artifact to me. Could anyone clarify whether FFV should be calculated from the polymer–solvent system or the pure polymer in such simulations? Thank you. Hakkim

When the adsorption energy of an organic compound on an Fe(110) surface was evaluated in the presence of 278 water molecules and five acid molecules using the Adsorption Locator module in Materials Studio, the calculated value was unexpectedly large (−3899 kcal·mol⁻¹). In contrast, when the same calculation was performed for the organic molecule in the absence of water and acid, the adsorption energy was much lower (−80.90 kcal·mol⁻¹). This discrepancy raises two important questions: first, what

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.

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
