WebClass to setup and run and analyze LAMMPS simulations which is a derivative of atomistics.job.generic.GenericJob. The functions in these modules are written in such the function names and attributes are very generic (get_structure (), molecular_dynamics (), version) but the functions are written to handle LAMMPS specific input/output. Parameters WebThe Tdamp parameter is specified in time units and determines how rapidly the temperature is relaxed. For example, a value of 100.0 means to relax the temperature in a timespan of (roughly) 100 time units (tau or fs or ps - see the units command). Tstart can be specified as an equal-style variable . In this case, the Tstop setting is ignored.
WebSep 13, 2024 · Dear LAMMPS users, I was trying to carry out a triaxial test on a sample of aluminum and oxygen atoms. In this test, initially, the RVE is equilibrated at a hydrostatic pressure of 5GPa and then an increase in the pressure in the z-dir from 5 to 7.5 is imposed and the pressure in the x and y directions is maintained at 5GPa using a “fix npt”. I … WebDescription. Turn off a previously defined dump so that it is no longer active. This closes the file associated with the dump.
WebJul 1, 2024 · Here I used Tdamp of $100\times \text{timestep}$ and Pdamp of $1000\times \text{timestep}$. I have changed different Pdamp value also and found that pressure … WebYour Tdamp and Pdamp parameters are quite high. Values equal to 100 timesteps for Tdamp and 1000 timesteps for Pdamp should work better. In order to lower the initial pressure add fix box/relax before minimization. You can output the data using fix print with "file" keyword. 4 votes 1 thanks Siegfried Fritzsche I am not familiar with this software.
