Yes Aleks that's what I meant. But I see now convergence with k points thank you

I see, thank you

Thank you so much!

​Dear Prof. Erba,

Thank you for your clear explanation.

Hi,

With CRYSTAL (from the PROPERTIES module actually) one can output the Hartree+EN potential in the all-electron case in 2D or 3D grids with POTM and POT3 keywords, respectively. In the latter case, the output is in .cube format. But I am afraid that currently there is no keyword to plot the XC part of the potential on a grid.

Hi Alessandro, thanks for the info! Much appreciated, Chris.

It was a great week! Let me share a group picture from the event:

QMMC2026_Volta_Redonda.jpeg

Thank you, this is too clear and very helpful.

Hi QMQDCHEM ,
Could you share your BAND.DAT file so that I can do some quick test?
Thanks

Thank you! This is much more comfortable.

Dear Alexander,
We runned a few tests, and, indeed, we found the same behavior. This, though, is not due to an error in the definition in the basis set, but rather to some formatting issue, since the Cs goes up to P4 the code expects that also the Iodine pseudo goes up to P4 and fills the missing coefficients and exponents with zeros.

Luckily there is an easy workaround to this, it is sufficient to flip Cs and I definition in the geometry and the results are the same as the one you obtained by defining the basis set in the input as you can see from my test.

I will leave you here two output snippets hoping that they help clarifying the issue:

Hi,

We have run some tests and we have identified the origin of the problem. The calculation fails in the evaluation of the Fermi energy in the NEWK option (so before getting to the BOLTZTRA step) because of large memory requirements due to a very large number of k-points being asked and because of the replicated-memory parallel implementation of that bit of code.

In that part of the code, with Pproperties (parallel version), data are replicated in memory by each process.

We have run tests on this system in parallel with different number of processes (on a computing node with 128 CPU cores) and for different shrinking factor parameters of the NEWK keyword. Results are summarized in the table below:

analysis.png

"ok" marks combinations for which the calculation run without errors. The trend is clear and can be rationalized as follows:

reducing the number of k points reduces memory requirments reducing the number of MPI processes effectively increases the available memory/process

Hope this clarifies things and helps find a way forward,

Hi,

I used space group 186 for ZnO that corresponds to the one you mention. In the character table printed by CRYSTAL only those irreps that are actually used to build symmetry-adapted Bloch functions are shown. I have updated my original post above to show the irrep labels in the character tables, which match those found in the printing of the eigenvalues.

Hope this clarifies things,

Poking further, since the last error is that of MPI and not of CRYSTAL, I launched the same input with NEWK 8 8 as a single-core process (with Pproperties), and this time the error was different:

85-C( 3 2 4) 86-C( 4 2 4) 87-C( 5 2 4) 88-C( 3 3 4) 89-C( 4 3 4) 90-R( 4 4 4) ERROR **** PROJVR **** NULL COMPONENT 0.222045E-15 0.100000E-07

for

ROTREF ATOMS 10 # this is Manganese 0 0 0 # I also tried this with different cell indices 12 # P5 0 0 0 8 # P2 0 0 0

and then

85-C( 3 2 4) 86-C( 4 2 4) 87-C( 5 2 4) 88-C( 3 3 4) 89-C( 4 3 4) 90-R( 4 4 4) ERROR **** RHOLSK **** BASIS SET LINEARLY DEPENDENT

for the following input:

ROTREF ATOMS 10 1 0 0 12 1 0 1 8 1 1 0

As well as for other indices

I have had the same problem in a slightly different task. I have found a solution, but it may not work for your particular task: I have reduced the number of k-points.
I am modelling Mn5+ ion in a AlPO4 cell in which one P is replaced by Mn.

Hi Jack,
compiling from objects on Apple Silicon is possible, but there are two critical requirements:

You must use OpenMPI built with the same GNU Fortran version used to compile the object files (in particular gfortran 12.1)

You must use the MPI compiler wrappers (mpif90, mpicc, mpicxx) instead of the plain compilers for the final linking stage

The default include file is almost correct. The only necessary changes are the compiler definitions. Replace the first lines with:

F90 = mpif90 LD = $(F90) PLD = mpif90

Keep the rest unchanged.

Important notes

The OpenMPI you use must be built against gfortran 12.1. You can check with:

mpif90 --show

or

mpif90 --version

and verify that it points to gfortran-12.

Do not mix different GNU Fortran versions (e.g. gfortran 13 or Apple clang).
A mismatch here is the most common cause of runtime failures.

Hi Jack,

the parallel version of CRYSTAL23 shipped for Apple Silicon is built with OpenMPI 4.1.1, therefore it is essential that the code is executed using the same mpirun version (or at least the same major version, ie 4.x.x).

If a different OpenMPI installation is used (for example the Homebrew 5.x one), the program may start but fail internally, leading to errors such as the abnormal SCF termination you originally observed.

Concerning the message ls: No match. this is just a standard shell warning printed when the ls command does not find the files it is looking for.
It is probably produced by the run script when it tries to list some output or scratch files that may not exist (for example if the job stops before all files are written).

It is not an error of CRYSTAL itself.

You may try searching inside the run script to locate the line containing the ls command. From the path and filename it is trying to list, you can understand whether the file is genuinely not produced or if the script is looking in the wrong path.

Hope this helps.

dmitoli Thank you, it was a formatting problem with my notebook, now the issue has been solved.
