Choose Machine Learning Models With Cross Validation

Machine learning techniques (https://www.d3view.com/introduction-and-application-of-d3view-ml/) are becoming unprecedentedly popular. And it plays an important role in data analysis. It is critical to find the model that demonstrates the best performance. Intuitively, we can build a few different models with the data given and see which model gives the best score, either it being RMSE (root mean…

Visualizing LS-OPT®Sampling points in d3VIEW

LS-OPT offers several sampling schemes among which D-OPT, Space filling and Latin Hypercube are among the popular schemes. Using d3VIEW’s LS-OPT output parser, the three schemes were used to generate experiments for variables that ranged from a mininum of 0.0 and a maximum of 1.0. Following images compare the distribution of the samples for all…

Commenting LS-DYNA Keyword Blocks

A clever way to comment out blocks of keyword can be easily achieved using the *COMMENT keyword. Example: In the following example, the keyword *MAT_ELASTIC and all cards until the next keyword is commented out by simply adding a *COMMENT in front of it. *MAT_ELASTIC 1, 1.0e-9, 210.00, 0.3 *SOME_OTHER_KEYWORD …. …. to *COMMENT*MAT_ELASTIC 1,…
