Vortices which occur in real materials are not permitted in smoothed micromagnetic calculations, but occur incorrectly in numerical calculations due to discretization. Some corrections are suggested. A method is proposed to permit large angles and multiple twists in intermediate steps of the calculations....
In the numerical renormalization group (NRG) calculations of the spectral functions of quantum impurity models, the results are affected by discretization and truncation errors. The discretization errors can be alleviated by averaging over different discretization meshes (z-averaging), but since each ...
Propagation of Errors In numerical methods, the calculations are not made with exact numbers. How do these inaccuracies propagate through the calculations? Underflow and Overflow Numbers occurring in calculations that have a magnitude less than 2 -1023 .(1+2 -52) result in underflow and are gener...
If no correlations have been directly defined between the quantities-with-error inexpr(usingScientificErrorAnalysis[SetCorrelation]),'correlations'=falsedoes not produce a result different from the default. 'correlations'=falsehas no effect on further induced error analysis calculations. That is, when...
Numeric errors refer to mistakes involving numbers, such as inaccuracies in numerical data, calculations, or representations of numerical values. These errors can include typos in numerical figures, miscalculations, incorrect use of decimals or fractions, and inconsistencies in numerical formatting. ...
Useful to differentiate a blank value that can be treated as a zero in numerical calculations from blank values that should be flagged as a potential problem if the value is used. NotFound 7 Record couldn't be found. For example, the record to be modified in the Patch function. Not...
In the HDL Implementation model, you can select either single- or double-precision data type when performing matrix computations. When you select single precision for numerical calculations, precision losses can result. For sufficiently stiff models, even small variances caused by this precisi...
Aliased and dealiased numerical simulations of a turbulent channel flow are performed using spectral and finite difference methods. Analytical and numerical studies show that aliasing errors are more destructive for spectral and high-order finite-difference calculations than for low-order finite-difference...
testcode is a python module for testing for regression errors in numerical (principally scientific) software. Essentially testcode runs a set of calculations, and compares the output data to that generated by a previous calculation (which is regarded to be "correct"). It is designed to be ligh...
In accordance with the invention, the PICA analyzer can be used to analyze chips where electrical tests have shown that correct behavior is obtained under some set of operating parameters, while incorrect behavior, such as numerical errors in calculations, is obtained under other operating conditions...
