Trythe software for free today! The professional titles are multiplatform and work on Windows, Mac, and Linux; one license allows you to use the software on all three operating systems. CurveExpert Basic is currently for Windows only.

CurveExpert Professional is a cross-platform solution for curve fitting and data analysis. Data can be modelled using a toolbox of linear regression models, nonlinear regression models, smoothing methods, or various kinds of splines. Over 90 models are built-in, but custom regression models may also be defined by the user. Full-featured publication-quality graphing capability allows thorough examination of the curve fit. The process of finding the best fit can be automated by letting CurveExpert compare your data to each model to choose the best curve. The software is designed with the purpose of generating high quality results and output while saving your time in the process.


CurveExpert Basic is a subset of the functionality contained in CurveExpert Professional and is intended for more casual/infrequent users. The list below is a specific list of differences between the two; the items are listed as features that CurveExpert Pro supports, but CurveExpert Basic does not.


I'm really impressed by the enhanced options of CurveExpert Professional, streamlined to give the professional the most quick answer to detect dependencies within its data, express them via formulas, and even calculate with them immediately. Definitively there isn't anything better on the market!


I find that Curve Expert Professional is more versatile and much easier to use than CurveExpert Basic, for example, when entering the initial guesses for the parameters. The graphics of CurveExpert Professional are far superior, as well.


As an Embedded Software Engineer who is involved with the control of medical devices, the ability to quickly determine the underlying relationship of easily-gathered empirical data is quite an advantage. CurveExpert has proven to be an invaluable tool when used in this respect and has saved countless hours of unnecessary effort. The information gained through CurveExpert is easily applied to process analysis, simulation and control purposes. CurveExpert's publication grade data plots make presentation and development documentation quite simple. The software is a real joy to use and the affordable price means this software has been created to be utilized by a wide range of end users from student to professional.


I use CurveExpert Professional infrequently but it is nice having that extra tool in your bag when you need it; especially when CurveExpert works easily, accurately and as automatically or manually as you choose. My application is sensors attached to complex SCADA systems where precision calibration of measurement data is required. A vendor will provide calibration data and a curve fit which rarely match. I use CurveExpert to resolve the disconnects. I do not use the majority of CurveExpert's capability but for the past 15 years CurveExpert has completely solved my sensor calibration problems. And the customer service CurveExpert provides is second to none.


We use CurveExpert [Basic] extensively in our research on probability distributions of forest fires. As an exploratory and analytical tool it is unparalleled in its flexibility, ease of use, and accuracy.


I have used CurveExpert [Basic] to fit some Temperature vs Time dehydration food data to give me a grounding for the basic fitting function to be used. One can then modify the basic fitting function accordingly to give meaning to the fit parameters calculated by curve expert. I especially find useful the automatic fit function.


I have used CurveExpert Basic for years and it is one of the most indispensible applications in my arsenal. CurveFinder is one of the most useful features in CurveExpert Basic and I will likely lean on it heavily in CurveExpert Professional. Does most of the hard work for you in coming up with the "best" curve fit.


I have just started to explore CurveExpert Professional and as I expected I am definitely going to upgrade. The new graph interface is very nice. A lot to work with there to get really high quality plots. The ability to use a subset of TeX is awesome. I use MathType from Design Science in Office documents so having TeX in CurveExpert Professional plots is a real plus for documentation.


In project design engineering, and other engineering activities as well, the evaluation of the physical phenomenon is greatly improved supported in the program, which allows the visualization of the behavior of the variables involved.


Tank settlement was, for a long time, elusive to me. I got by only whith was needed for the exam. If you are an API 653 inspector, there are many opportunities to do inspection or consulting jobs in small tanks. The following is an introduction to the subject of settlement.


Uniform settlement. This component often can be predicted in advance, with sufficient accuracy, from soil tests. Uniform settlement does not induce stresses in the tank structure. However, attention should be paid to pipe connections and other attachments.

Rigid body tilting of a tank (planar tilt). This component rotates the tank in a tilted plane. The tilt will cause an increase in the liquid level and, therefore, an increase in the hoop stress in the tank shell. Failures of most concern are: (1) Distortion of shell such that the floating roof malfunctions; and (2) rupture of the shell or bottom plate or shell bottom plate connection. The settled location of the tank shell, after rigid body tilt, can be represented by either a cosine or sine wave with respect to its original position in a horizontal plane.

Out-of-plan settlement.While uniform settlement and rigid body tilt of a tank may cause problems, the out-of-plane settlement is the important component to determine and evaluate in order to ensure the structural integrity of the shell and bottom. Based on this principle, a common approach is to determine the magnitudes of the uniform settlement and rigid body tilt (if a rigid tilt plane exists or can be identified) for each data point on the tank periphery.


The plane of rigid tilt settlement, if well-defined, is represented by the optimum cosine curve. Several methods exist for determining the optimum cosine curve. The least accurate method is by free hand drawing techniques, a kind of trial and error procedure to fit the best cosine curve through the data. A better method is to use the mathematical and graphical capabilities of a computer


Besides, curveexpert, I used Microsoft Excel to find the value of R2. With excel, I found a value of R2=0.888. This is because I used 40 points, while Curveexpert uses I dont know how many more. Lesson is: the software is better approximating a curve.


The cosine curve in this example fullfills the requirement of API 653. But what happens when it doesnt fulfill the requirements? When there is no optimal cosine curve? That will be the subject matter of another article.
