C&R Technologies, Inc. announces that Version 5.4 of SINDA/FLUINT, Sinaps®, Thermal Desktop®, RadCAD® and FloCAD® are now available

Boulder, Colorado — C&R Technologies, Inc has announced that Version 5.4 of SINDA/FLUINT, Sinaps®, Thermal Desktop®, RadCAD® and FloCAD® are now available for download from the web site. "Our development group has introduced a new strategic roadmap to ensure future development produces the best tools in the the industry and will support the ever-changing needs of our clients" stated president Brent Cullimore.

Part of the 5.4 release is the arrival of two new tools, CRTech Thermal Workshop and CRTech SpaceClaim which support the Thermal Desktop product suite by providing improved connection to various CAD tools.

SINDA/FLUINT Revision Highlights

Full Double Precision: While key parts of the solution have always been double precision, the size of all real (and integer) variables has been extended to exploit the availability of greater accuracy. No changes to models is required.
“Pool Boiling” (HTP) Ties: In many situations, such as on the insides of vessel walls, convection coefficients can be calculated even though the fluid is quasi-stagnant and forced convection is not appropriate. For those situations, and to make it easier to model pool boiling, a new type of tie has been created.
Controllable Orifices: Orifices can often be used as models of partially opened valves. This fact has been exploited in extensions of the ORIFICE connector device to create orifices that can be commanded to open or close, or to maintain a constant upstream or downstream pressure. These options add more realistic transient behavior for modeling valve events and regulators.

Sinaps Revision Highlights

Tables: This new feature provides a familiar grid structure for inputting columnated or tabular data, greatly simplifying the generation and maintenance of traditional SINDA/FLUINT arrays. The grid structure allows data to be pasted from other applications including Microsoft Excel™. Tables can be scaled using registers or expressions and are identified by descriptive user-definable names.
Redesign of Turbomachinery Forms: The input forms for pumps, compressors, and turbines have been redesigned to provide a more user-friendly interface and to assist the user in determining which inputs are required. These device models may now be stored in user libraries to facilitate their reuse in multiple

Thermal Desktop/RadCAD/FloCAD Revision Highlights

Tag Sets: This new feature has been added to allow assigning groups of items to network elements such as heat loads, conductors, contactors, ties, etc. Tag Sets are persistent and can have all entities replaced or removed without losing the definition of the referring network element (conductor, etc). The Tag Set Manager organizes the Tag Sets and allows assignment of entities to the Tag Sets.
Mesh Importer: The new Mesh Importer brings externally created finite element meshes into Thermal Desktop under a controller object. The controller object allows the mesh to be repositioned in the thermal model and also serves as a light-weight post-processing tool. Mesh updates? Those are handled through a simple reimport operation that replaces the previous mesh with the new one in the repositioned location. To facilitate updates, node and element groups from the meshing tool are imported as Tag Sets to maintain all thermal connections and heat loads defined using Tag Sets.
New Cutting Plane Tool for Post-processing: A new cutting plane tool is available to visualize internal temperature gradients of solid objects (both finite difference and finite element).

Autocad versions 2004, 2005 and 2006 are no longer supported. Additionally the built-in compiler version of SINDA/FLUINT will no longer be available for purchase or upgrade. Current users should convert to Intel compiler version of SINDA/FLUINT. Please contact us about Autocad upgrade and compiler conversion options.

Customers under current support contracts may download the updated versions for free, however they will need to contact the support department for new license files. Customers who no longer are under current support contracts should not install these new versions without first contacting the sales department to upgrade to the newer versions.
