Input files and parameters / Could NOT open file: RestartInitial/System_0/restart*

« on: November 04, 2022, 03:01:57 PM »

I am trying to run a desorption simulation where I have the highest pressure as the input for the lower pressure. Howver, I am getting this error Could NOT open file: RestartInitial/System_0/restart*
anyone knows the problem

Input files and parameters / mol file

« on: October 13, 2022, 12:51:04 PM »

How can I use a .mol file in RASPA. The mol file has all atoms and charges can I use it instead of cif and pseudo atoms or it has a specific way to be added. Also what is the command to read the .mol file in simulation input

Input files and parameters / desorption-example

could someone share an example of a desorption study. RASPA is reporting excess and absolute adsorption so is it the parameter I have took at to check the desorption? or I have to do a specific type of calculation

Input files and parameters / desorption-error

hello
I'm trying to perform a desorption study but whenever I run it, it shows an error of core dumped segmentation fault(simulation input).(I'm using a .sh script to run)
why I'm getting this error? and if there's any way to just read the adsorption restart file?

can we create two temperatures one for the adsorbent and another different temperature for the adsorbate?

can anyone share TIP4P model info such as .def file and lennord Jones parameters I want to re check my work couldn't find anything online

Output files / output - molcules/unit cell - IMPORTANT

« on: April 21, 2022, 12:03:20 PM »

in the output folder the parameter Molecules per unit cell, does it mean the unit cell we assigned in the beginning of simulation ex( 4 2 2 ) or the simplest unit cell which is (1 1 1).

I want to know if I need to do further calculation to match the exp or this is the final value

Input files and parameters / UNIT CELL and affect on adsorption output ---- important

« on: April 18, 2022, 01:16:32 PM »

Hi

How does the unit cell in simulation input file change the output of absolute adsorption. If my experimental data reports a MOF with a unit cell of 1by1by1 and for my raspa folder I had to put 4by2by to avoid error. Do I need to divide my final output by a different volume to match the unit cell in EXP or those values simplified per unit cell??

Input files and parameters / lennard jones parameters

« on: April 18, 2022, 10:21:18 AM »

Hi all
I have a question regarding lennard jones parameters in RASPA. What are the units used? And if my energy parameter is in Kj/mol how can I convert it to the used unit in Raspa
