While basis set convergence sounds straightforward (though time-consuming) it is hard to rule out that underlying assumptions in the design of the basis set influences the results. However, converged basis set DFT results are needed to separate basis set errors from errors due to the functional. Multiwavelets, a systematic and adaptive multiresolution numerical solution of the …

International collaboration demonstrates reliability of quantum simulations for materials design
An international collaboration with colleagues from over 30 universities and institutes to investigated to what extent quantum simulations of material properties agree when they are performed by different researchers and with different software. Thanks to an online collaboration, they successfully demonstrated that the most recent generations of codes agree well, in contrast to earlier generations. …
