This function writes out a VTK-file, a 3D histograms of the density. See the examples on Visualization.
You could also read this file yourself.

The DREIDING force field uses specific functional forms and parameters. You can look these up and use (most of) these in RASPA.

Input looks, at first sight, okay to me. Remove as much as possible, i.e. component 1-3 etc, and check if it works. Then from add the components one by one to see where it goes wrong.
In general, change stuff in small steps, otherwise it is harder to debug.

I don't think this is currently possible. The implementation of the CBMC algorithm used for the insertion is the limitation here.

No, the pressure is indeed not used in this example.
I will remove the pressure line in the example.

Have a look at the example rigid molecules in RASPA, e.g. CO2.
Numbering starts at zero.

That is hard to say based on this information. Always try with the latest version (2.0.45).
If it crashed, then use a debugger to find out why it crashes (section 5.5 in the manual).

No. For MD, you're better off using LAMMPS which is parallel and very fast.

Adsorption is most difficult to compute at low temperatures where the system might get stuck in meta-stable states. With parallel-tempering and hyper-parallel tempering you overcome these free energy bottle necks. Also techniques like expanded ensembles help to overcome the problem of low insertion/deletion rates.

 I am not using windows myself, but you just have to setup your setup the compilers.
There are also unix-like environments under windows like the 'WSL' (windows subsystem for linux) and MSYS.

You should be able to add an 'ellipsoid'. See the IRMOF-1 example in the 'primitives' section of the Gallery.

Apparently, the new Ubuntu removed sysctl. I have replaced sysctl by uctsname.
Please update to v2.0.42, and check whether it now works for you on Ubuntu 20.10.

Drag the MFI-example to your local projects so that it is editable. Then select the channel in the 'Scene Navigator' (See help).
After that go to the detail-view called 'Appearance' on the right, and set the properties of the 'primitive' (like the color and shape/size of the cylinder primitive).

It is a standard example of iRASPA. It is in the gallery examples.
