Opening Reinforcement Design

For now (version 1.0.0), only International Unit System[ 2 ] or just SI Units is accepted, but we're working to implement the Imperial Unit System[ 3 ] in the following versions, as it's still used by many countries (specially USA) and companies.

The module tab have two versions: one for a new part (see Fig. 4.1.1) and one for an existing part (see Fig. 4.1.2). The difference is that when a part is saved, an unique identifier (ID) will be generated for it and it can be linked to other parts and equipment. The ID is shown above the Module tab (see Fig. 4.1.3) and there's a button to Project Management module beside it.

The sharing option is something that we thought would be useful because engineers works as a team and usually share their projects with another engineers or customers, either to review or for approval.

Nowadays working side by side (physically) with other engineers is becoming something from the past. Hybrid and Remote position are becoming common in many companies. So no more printing the project and let in the co-work table to be checked. You either send the PDF (or software file) by e-mail or save it in the company drive.

Our approach is a little bit better. We let the USER choose which USERs can access the project, equipment and part and what kind of permission they will have. You can let some USERs change anything in a Part or let they only see it (input and output).

To share a project, equipment or part you must be its owner. You can be the owner by either creating the project, equipment or part or if the current owner delegates it to you. Also the option Disable sharing of this Part? in the Settings tab must be set to No (see Fig. 4.5.1), in case of Part and if it's a Project or Equipment, the sharing button in the PJM module must be set to enable (see more about it in the Project Management documentation).

Currently there are two types of sharing status:

1. Full Access: this type of access let the USER make changes to the Project, Equipment and Part but can't delete it (only its owner can do that)
2. View Access: USER with this type of access can't make changes, can only see the input and output data.

At the bottom of the page you'll find three buttons (see Fig. 8.4.1.):

• Back: will bring the USER back to the Input page
• Save: will save the Part and the USER will be able to access it using the direct link shown in the browser or through the Project Management module
• Report: will generate and download the Calculation Report

To help USER easily check the equations and input data we created a summary which is show at the right side of the page (see Fig. 8.5.1.). It's composed by hyperlinks and if clicked the part where the item is located will be show. The list is divided in Input and Output to facilitate the identification.

The calculation modules that we've in the ΣCalc or, more specifically, in the MarsCalc package, works independently from each other. It means that, if you are designing a spherical head to be attached in a conical shell, one part will not "know" about the other. The only exception are the modules that require the USER to load data from other modules. It's the case for Opening Reinforcement Design (ORD) and Saddle Support Design (SSD).

To let the USER specify which parts are connected, we created the reference list. Let say, for example, that you have a torispherical head connected to a cylindrical shell. If you go to the Equipment tab in the Project Management module you'll see that the equipment have many parts, including the head and shell specified above but, you can't know how they are connected. If you add the cylindrical shell as a reference to the torispherical head, you'll know that it's connected.

The problem now is: what if the cylindrical shell have two heads, how can you know which one is in the top and which is in the bottom? Unfortunately we don't have a way to specify that, we're planning to let USER to assembly the pressure vessel just like PVElite does (using 2D drawings and nodes to connect the parts) but it isn't our top priority (it is listed in the Pool of Ideas with the ID # 9FF565B5)

Okay, lets go to the how to part. To add a part as a reference, first make sure that both parts are saved (exist and have and ID), then click in the Add part as a Reference (see Fig. 4.1.2) button. A modal (see Fig. 10.1) will be shown with the list of all parts created by the USER. If there are too many parts and you already know the ID of the part that you which to add, just type it in the search field to filter the list. To finish, just click in the part that you want to add and the modal will close and it'll appear in the Parts Linked to this Part table in the Module tab.

One important thing that you must understand: linked parts have no effect in the calculation. It serves only as a reference. So if you add a stainless steel part to a carbon steel, the application won't show any warning.

Calculation report can be generated and downloaded by clicking on the Report button located in the bottom menu, which is only visible in the results page. The file name will be the part ID.

Fig. 11.1. shows the information contained in the first page of the report. Company name and logo can be set in the Dashboard. All the other information are automatically generated.

The second page will show the part description (information given by the USER in the Module tab), part id (automatically generated), drawing (same as shown in the input page), input and output (equations).
