Run steady-state simulations of continuous chemical processes with CC-STEADY STATE. This product features libraries of chemical components, thermodynamic methods, and unit operations, enabling you to simulate processes from lab scale to full scale.
Take steady-state simulations to the next level of fidelity and conduct dynamic flowsheet analysis with CC-DYNAMICS. The possibilities are endless: operability check-out, PID loop tuning, operator training, even online process control and soft sensor functionality.
New features in Version 3 of the HYDROTHERM simulator have been verified using four test problems. Three problems come from the published literature and one problem was simulated by another partially saturated flow and thermal transport simulator. The test problems include: transient partially-saturated vertical infiltration, transient one-dimensional horizontal infiltration, two-dimensional steady-state drainage with a seepage surface, and two-dimensional drainage with coupled heat transport.

Clicking HERE will download a zip archive called tables.zip. Use Win Zip or equivalent to extract the following 3 files, which are in tab-delimitedtext (ASCII) format. It should be possible to read them into a spreadsheetprogram or text editor. They contain both text (row labels and units) andnumerical data, so you may need to re-format before reading into Matlab,etc. The files give operating conditions at 6 different steadystate operating conditions described in the paper Optimal Steady stateOperation of the Tennessee Eastman Challenge Process, N. L. Ricker, Computers& Chemical Engineering, Vol. 19, No. 9, pp. 949-959(1995).
To verify a steady state I suggest that you call subroutine tefunc(part of teprob.f) to calculate the derivatives for thegiven states and manipulated variables. All derivatives should beless than 1.e-3. You can also use the te_mex function in Matlab.
Define the criterion and limit for assessing steady state performance. Thefirst parameter designates the criterion whereas the second parameter setsthe threshold. When the criterion falls below the threshold for thespecified duration, the job will stop. For example, iops_slope:0.1% willdirect fio to terminate the job when the least squares regression slopefalls below 0.1% of the mean IOPS. If group_reporting is enabledthis will apply to all jobs in the group. Below is the list of availablesteady state assessment criteria. All assessments are carried out using onlydata from the rolling collection window. Threshold limits can be expressedas a fixed value or as a percentage of the mean in the collection window.
A rolling window of this duration will be used to judge whether steady statehas been reached. Data will be collected once per second. The default is 0which disables steady state detection. When the unit is omitted, thevalue is interpreted in seconds.
Allow the job to run for the specified duration before beginning datacollection for checking the steady state job termination criterion. Thedefault is 0. When the unit is omitted, the value is interpreted in seconds.
Whether testing electromechanical or microprocessor-based relays, performing steady-state, dynamic, or end-to-end system tests, RTS offers a straightforward, consistent user experience regardless of which of the supported relay test sets are used.
The comprehensive set of steady state test templates included in RTS cover the gamut of conventional and modern relay types, models and styles. Assemble steady state tests into folders within RTS test routines for automated sequences that verify relay protection elements during acceptance testing, commissioning and routine maintenance.
RTS software is intended for users to develop test creation skills confidently. Steady state tests built from the FasTest interface can be enhanced with many functions that are provided with RTS Developer tools in other parts of the user interface. Powerful test sequences can be developed that utilize data imports, message windows, scripted functions, and more.
Whether using steady state, dynamic, or even manual test sequences, RTS provides a robust framework for developing system tests that perform exactly to your requirements without compromise. Any set of tests within a test routine that you define for use in end-to-end test sequences are easy to categorize and execute at local or remote terminals. The users performing end-to-end tests do not need to have matched test sets because RTS compensates for timing differences of supported test sets in the software. 2b1af7f3a8
