Advanced Design

C&R Technologies is dedicated to producing software tools that not only help thermal/fluid engineers produce analytical answers but also product solutions. Whether you are using the nongeometric analyzers or the CAD-based geometric analyzers, you can apply advanced techniques that transcend traditional steady state and transient simulations.

With our advanced techniques, the uncertainties that abound in thermal/fluid modeling can be treated by a combination of calibration to available test data, and a statistical evaluation of the influence of the remaining uncertainties. Automated techniques are available to assist in both tasks. Traditional steady state or transient "point design evaluation" analyses then become a subprocess of a larger system that provides decision support at a higher lever.

Parametric Modeling:  Rapid Changes, Sensitivities

  • Use algebraic expressions and spreadsheet-like variables instead of hard-wired numbers as inputs
  • Make rapid and consistent model changes not only between runs, but also during a simulation run
  • Find out how easy and important it is to make parametric variations, to perform sensitivity analyses, and to answer what-if questions

Optimization:  Design Synthesis

  • Size dimensions, select and locate components, and find an optimal design solution
  • Designate variables to be sized or selected, objectives to be met, constraints and limits to be obeyed, and an arbitrarily complex solution procedure with which to evaluate candidate designs. The software automatically searches for the best viable design

Size, Select, Locate, Optimize

Automated Model Calibration to Test Data

  • Adjust uncertainties in a model automatically, correlating to available test data
  • Designate uncertain inputs, limits on their range, when and where to compare to test data, and how to define a "good fit"... the rest is automatic

Critical Design Case Definition

  • Find the combination of input values that yields the worst-case design scenario
  • Determine the hot case and the cold case given ranges of possible dimensions, environments, properties, component efficiencies, etc.

Reliability Engineering:  Uncertainty Analysis

  • Check margins and safety factors for adequacy
  • Given variations in inputs, find the chances that failure criteria will be exceeded
  • Evaluate uncertainties statistically

Robust Design:  Designing For Reliability

  • Synthesize designs based on reliability
  • Determine allowable tolerances and acceptance criteria

Avoid Costly Overdesign and Risky Underdesign

Multidisciplinary Design Integration

C&R provides the most comprehensive set of thermal/fluid design and modeling tools available to the heat transfer and fluid flow professional. However, designing reliable products in the shortest possible design cycle time demands inclusion of other engineering specialties such as structures, electric, optics, and cost.

C&R goes beyond intimate interconnections to other software design tools. Our tools are also designed to allow integration into large-scale multidisciplinary design systems and analysis management tools. Contact CRTech for more information on supported interconnections and on developing customized design environments.

FloCAD online training

Class times: May 2 & 4 from 10am to 2pm MT

Cost: $425

This online class will provide an introduction to fluid modeling components within FloCAD. The class will be held over a 2-day period, with daily sessions running approximately 4 hours each. The class uses a mixture of lecture, demonstrations, and self-paced tutorials to allow attendees to practice building fluid system models and interpreting results. The presentations will comprise 2 - 3 hours of each session, and the instructor will be available during the remainder of the time for questions during tutorials. Attendees must have basic working knowledge of SINDA and Thermal Desktop as these topics will not be covered but their usage is required for FloCAD.

Using Sinaps? It is not too soon to get started with TD/FloCAD!

This webinar describes the process for converting from Sinaps to Thermal Desktop (TD) and FloCAD. This process includes using an exporter which works with Version 6.0 of the CRTech tool suite (expected to be released in May of 2017).

Come learn about the basics of TD/FloCAD, including many compelling features not available in Sinaps. The webinar will also cover how to manage the transition period, during which you may be using both programs simultaneously. This is also a chance to ask questions.
