 | Applies to TK Solver 5.0 Regular and Premium Editions. |
This update includes a significant upgrade to the NIST fluid property functions in TK, as well as the REFPROP utility in the Wizards menu. A complete summary of the new features is included in the on-line TK documentation. Here are a couple highlights. Water vapor and hydrogen can now be included in fluid mixtures. The maximum number of mixture components has increased to 15.
This update will overwrite the files your existing FLUIDS and MIXTURES folders in the TKExtLib folder of your TK Solver installation. If you would like to retain the old files for any reason, rename them prior to installing the update. |

 | New in ASD 6.0.11: |
ASD 6.0.11 allows for input of arms angle in the power user forms of the torsion spring programs. We do not encourage you to use arms angle as an input however as it provides ambiguous information and the solution will not be unique. For example, if the arms angle in the free position is 225 degrees and is 60 degrees with a load applied, what was the deflection? Was it 195 degrees? 455 degrees? Clearly, more information is required. We suggest that you use coils and deflections instead of arms angles, as that provides unambiguous information to the program and the solution will be unique.
Life estimates have been added for all compression, extension, and torsion spring programs.
Power springs now include an option to use 50% of the available space. This adds one additional constraint when this option is activated.
A keystone factor option is included for rectangular wire torsion springs. When this is used, the body length increases slightly.
The Torsion Springs models have been overhauled in several key areas. New variables were added for contact forces on each moment arm at each load condition. Individual moment arm lengths are now specified in the geometry section of the power user form. Estimated cycle life is now reported (except for double torsion springs; we are looking into adding that in the next update). The default text height in the DXF image is better calibrated.
Estimated cycle life has been added to compression springs. We expect to have this added to the extension spring models in the next update.
The check for updates via the Help Menu is now working again. We recently moved the update location, breaking the link to the older Help menus.
Bug Fixes in ASD 6.0.11:
If there were more than two caution messages, only the first two were displayed in the report.
DXF text in metric images was too small.
Outstanding Issues for Future Updates
Increase the number of decimal places in several of the fields.
Change the metric spring rate to N/mm instead of N/m. |

TK Player has been updated to take advantage of the new features in the TK Solver Excel Toolkit. See the TK Solver update notes for more details on those features. TK Player runs applications created using the TK Solver - Excel Toolkit. The Toolkit has recently been enhanced to allow for linking lists of arbitrary lengths. Previously, the list length was set at the time of linking and could not vary as the inputs to the TK model varied. This update removes that restriction. Individuals who had previously downloaded TK Player must download this update to run any new TK Player applications created using this new feature. |

 | New in IRF update 7.0.4 |
Additional text was added to the menu descriptions, particularly in areas where cases can be merged.
Plot labels were improved throughout.
Redundant equations were added to some cases involving hyperbolic functions to avoid extreme values. For example, if A = sinh(350), B = sinh(400), and C = cosh(400), then A*B/C causes an exponent overflow error because A*B is too large. However, since B/C = tanh(400) = 1, A*B/C = sinh(350) which can be computed.
Plates -- Large Deflections: Instead of lumping all the cases into a single model, individual models are now presented and they are more flexible (backsolvable)
Some of the cross section properties (distances from the neutral axis) for unequal leg angles were calculated incorrectly in 7.0.2 and have been corrected in 7.0.4. |
