CAEPIPE Version 5.1
CAEPIPE Version 5.1
Support load summary is now available (displayed under the Results menu upon entering Output).
Force spectrum analysis is now available. Enter Force spectrums and then Force spectrum loads as data in the Layout screen (similar to Time History).
Conversion of a time function to a force spectrum is available. After entering a time function (under menu: Misc > Time functions), go to menu: Misc > Force spectrums. Select menu: File > Convert time function command.
A new analysis option is added to solve Thermal case = Operating - Sustained, i.e., instead of solving thermal case independently, thermal case results are calculated as the difference between the Operating case and the Sustained case results. This is a recommended procedure to solve thermal cases (T1, T2, T3) especially when nonlinearities (limit stops, friction etc.) are present. Option is available under menu: Options > Analysis...> Temperature.
Wind load is now specified as wind pressure versus elevation or wind velocity versus elevation. Previously constant wind velocity was specified.
A Hydrostatic test (hydrotest) load case is now available. The hydrotest load is defined by the specific gravity of the test fluid, the test pressure and whether to include or exclude the insulation weight. The hydrotest load can be constant over the whole model or can be changed or even excluded in parts of the model. The hydrotest load is defined by pressing 'h' on an empty row in the Layout screen (similar to pressing 'c' for a comment). This load is applied to the rows that follow till changed by another hydrotest load).
A Tie rod element with different stiffnesses and gaps in tension and compression is now available (useful for modeling tierods in bellows, chains etc.).
For hinge and ball joints, rotation limits can now be specified.
For a guide, a gap and a connected node can now be specified.
For a bend, SIF can now be specified (useful for FRP bends). If an SIF is specified, it is used instead of the piping code specified SIF. If a user SIF is also specified at bend nodes (A and/or B nodes), it will be used instead of the bend SIF or code specified SIF.
Piping code = None for non-code analysis is now available.
For Piping code = None, Von Mises, maximum and minimum stresses are calculated.
Node numbers are automatically incremented. When you press Tab or Enter from a blank Node column, an automatically generated node number is assigned. The automatic increment can be turned off by not specifying a node increment. The node increment can be specified by menu: Options > Node increment.
If the last row of layout is empty and the previous row is a Pipe or Jacketed pipe, pressing Ctrl Enter will duplicate the DX, DY, DZ and the Data (if the data does not have a connected node and is not a nozzle, an end cap or a branch SIF). The node number is automatically generated, too. So, pressing Ctrl Enter can quickly generate long runs of straight pipe with many elements. This is especially useful for sloped pipes. This command is available under menu: Edit > Duplicate last row. The Node increment must be set to a non-zero number.
Slope for an element can now be specified. Using the input length and direction (specified in terms of xcomp, ycomp and zcomp which could be direction cosines), DX, DY, DZ for the element is calculated and entered on the Layout screen. This can be used to change the element length, too. Slope is available under menu: Edit > Slope.
Clicking on DX, DY, DZ headers or right clicking or double clicking in the DX, DY, DZ columns brings up a menu for editing. You can Insert or Delete a row, split or specify Slope to an existing element.
Color-coded stresses are now shown by pressing the stress or stress ratio buttons in the Sorted stresses window. Previously, pressing the Render button in the graphics window showed them. Whether to show color-coded stresses/ratios or show values of stresses/ratios is done by the menu: View > Color code stresses.
Animation of the deflected shape is now possible. A button on the toolbar in the Displacements results screen or menu: View > Show animated deflected shape may be used.
Jacket pipes are now rendered transparent so core pipes can be seen through them.
Center of gravity calculation is now available. It can be seen in Results under the View menu.
Revised material properties. The most significant change is the density of carbon steel that changed from 0.280 to 0.283 lb/in3.
The status of Layout and List windows is saved with the model so the model can be opened in the same state as when it was saved.
An attempt is made to save model (if modified) after a crash or assertion failure.
In the startup window, the shortcut for "Open last model" changed from "Ctrl+Shift+O" to "Enter"; so pressing "Enter" in startup window will open the last model. Also the mouse is placed on the "Open last model" button so it can be clicked (without moving) to open the last model.
For API 610 (8th Edition), the allowable principal stress for vertical inline pumps was changed from 6000 psi to 5950 psi to be consistent with 41 MPa in SI units.
Some context sensitive help is available. Click on '?' button in the dialog (if shown) or press F1 for context help. Also in the list window, for some lists, pressing F1 will bring up context sensitive help.
Bug correction: In modal analysis, the rod hanger stiffness was used from the previous load case rather than the first operating load case. Thus if load cases existed between the first operating load case and modal analysis (such as operating case2 (W+P2+T2), wind, seismic etc.) proper rod hanger stiffness was not used.
Bug correction: Snubber loads for time history and harmonic response load cases were not printed.
Bug correction: Specified displacements for nozzles were not shown in graphics.
