About

NLREG is a powerful statistical analysis program that performs linear and nonlinear regression analysis, surface and curve fitting. NLREG determines the values of parameters for an equation, whose form you specify, that cause the equation to best fit a set of data values. NLREG can handle linear, polynomial, exponential, logistic, periodic, and general nonlinear functions. Unlike many "nonlinear" regression programs that can only handle a limited set of function forms, NLREG can handle essentially any function whose form you can specify algebraically. NLREG features a full programming language with a syntax similar to C for specifying the function that is to be fitted to the data. This allows you to compute intermediate work variables, use conditionals, and even iterate in loops. With NLREG it is easy to construct piecewise functions that change form over different domains. Since the NLREG language includes arrays, you can even use tabular look-up methods to define the function.

About

Simcenter Simsolid is a Siemens simulation and structural analysis tool that helps designers and engineers analyze fully featured CAD assemblies without geometry simplification or meshing. By removing two of the most time-consuming steps in traditional FEA, it allows teams to validate structural performance much faster. The software can handle large and complex assemblies, including models with rough contact surfaces, gaps, or overlapping geometry. Simcenter Simsolid delivers accurate results in seconds to minutes on a standard PC, making it useful for rapid design comparison and simulation-driven development. It supports a wide range of analysis types, including linear and nonlinear statics, thermal analysis, modal analysis, fatigue analysis, dynamic simulations, buckling, composites, and random response. With CAD interoperability, advanced connections, materials, boundary conditions, and visualization tools, Simcenter Simsolid helps teams bring better products to market faster.
