Testing by adding and eps to the whole matrix So there are subtle differences in the noise floor below eps, but that should not be the issue with the "SVD not converge here".

PC: Windows 7 Service Pack 1 - X64, Intel i5-4590 Output in Matlab 2018a of the commands you suggested:Ĭonfirmed problem here, "SVD did not converge", which shouldn't happen.

If you find a way to adjust the code (or at least to return a readable error that tells the user what should be fixed in the data). Right now it just crashes abruptly with red errors in the command window. Wee need to add ways to handle correctly these cases.

Here is the dataset, ready to load in Brainstorm with File > Load protocol > Load from zip file: The EEG data was pre-processed in EEGLAB with ICA (at least 3 components related with subject artifacts were removed) The noise covariance matrix is estimated from the pre-stim baseline of the individual trials, as indicated in our guidelines. The data comes from the dataset attached to an article describing an EEGLAB+Brainstorm pipeline to process simple EEG experiments (soon to be published in the same Frontiers research topic as the new brainstorm article). I don't know if "econ" and 0 trigger different conversion routines, but the first case should still work anyway, since it only finds the singular values, and does not iterate to find the eigenvectors, which is where I believe the SVD function fails to converge.

If you have time before I install 2018a, try Sn = svd(Cov) vs = svd(Cov,0) vs = svd(Cov,'econ'). Hence the "failure to converge", which I have seen happen before.

If the libraries changed so that they are now considered to be zero, then the SVD is challenged with finding eigenvectors in a null space of 16 zeros. Relative Epsilon is 10^-16, so eigenvalues 49-63 are on the hairy edge of being in the bit noise. Singular values 49-63 are about 10^-25, 64 is 10^-28, relative to the first singular value at 10^-11. The rank of Cov, in this example, is actually 48 out of 64.

While OpenFOAM provides a reliable free alternative, FLOW-3D has a faster setup and makes the simulating experience apt for beginners.May give the different libraries used across versions and architectures.

Results validate the use of the free and open platform OpenFOAM as a viable alternative to commercial ones in the domain of fishway design and assessment. Both platform codes reproduced the scenario under study, concurred with experimental data and offered a superior performance on flow structure velocity simulation than turbulent kinetic energy. Mesh independency was assessed through LES IQ index and the numerical models' accuracies were evaluated comparing representative hydraulic variables (velocity, its components, and turbulence kinetic energy) with ADV experimental data and discussing results in previous studies. In this study, in contrast to previous comparative studies, turbulence was addressed using LES approach and the volume of fluid method was used to model the multiphase interface (air-water). Considering previous comparative studies, our initial hypothesis is that both OpenFOAMs' multiphase solver and FLOW-3D provide good comparable results. The objective of this study is to make a comparison between two 3D CFD platforms: OpenFOAM (free and open-source CFD software) and FLOW-3D (closed source commercial CFD software), focusing on vertical slot fishways, one of the most widespread solutions to facilitate the fish migration through transversal obstacles in rivers.
