So far, we have only entered the data relevant to our vessel, and produced the model on the screen. In this section, you'll understand the Status Bar fields.
-
Select the main shell in either the 2D or 3D view.
The main shell element is highlighted.
-
Look at the bottom of the screen to the status bar:
The status bar gives us a lot of information for the selected component. Consider the fields from left to right:
El# 2 of 3 : Component number 2 of 3 components (from the bottom)
Fr: 0.00 To: 4.00 ft : Element spans from 0.00 ft to 4.00 ft from the datum line
Up: : Element orientation
Tr: 0.3057 : Computed thickness for the internal pressure (120 psi)
Mawp: 206.8 : MAWP for this element (206.8 psi)
MAPnc: 275.6 : Maximum allowable pressure new and cold (275.6 psi)
Trext: 0.328 : Computed thickness for the external pressure
Slen: 22.7 ft : Maximum unsupported length for the external pressureLet us now see what happens when there is a problem with an element.
-
Go to Finished Thickness field and change the thickness from 0.5 inches to 0.2 inches.
-
Now look at the status bar at the bottom of the screen:
The required thickness for the internal and external pressures now appears in red, indicating that there is a problem. In our case, the problem is the thickness.
-
Change the finished thickness back to 0.5 inches to fix the problem.
