Q: I have tried for almost (1) week to download this program correctly and my computer will not accept it. After speaking with fellow classmates we have realized that it is because I have Windows XP Home Edition.
A: I don't know what is causing this problem. I'd appreciate hearing from others who have experienced this problem. Also, MDSolids has not yet been tested with Windows XP. I don't know whether XP will run MDSolids or not.
   
Q:
I have a registered copy of 1.7.5 MDSolids program. I have recently downloaded Version 2.0 version. Am I supposed to pay for this new version or is it a free upgrade?
A:

The cutoff date for free upgrades is January 1, 2001. If you purchased MDSolids after January 1, 2001, you are entitled to a free upgrade to the Student Version of MDSolids 2.0. The features of MDSolids 2.x Student Version are generally analogous to Version 1.7.5 although there have been many enhancements. The most notable additions are more fully described in the Purchase section of this website.

The Full Version of MDSolids 2.0 contains new conveniences that have not been available in previous versions. These features are also described in the Purchase section of the website.

While I would like to extend free upgrades to all licensed users of MDSolids, I hope that you can understand my decision to establish a cutoff date in view of the low $18 purchase price that you originally paid for an MDSolids license.

   
Q:
I bought the Wiley book by Roy R. Craig containing a CD for MDSolids Version 1.7.5. Am I entitled to the free upgrade to Version 2.6?
A:

The version of MDSolids that you obtained with the Craig textbook is controlled by John Wiley and Sons (the publisher), and I am legally prohibited from making any changes to this version of the software without their consent. If you want to retain access to the Craig Example Problem Supplement, you'll need to continue using the version of MDSolids that came with the textbook.

MDSolids Version 2.6 is an entirely separate entity from the Craig Version of the software, and it does not include the 90 example problems included in the Craig Example Problem Supplement. If you want to use MDSolids Version 2.6, I'd be delighted for you to do so, but you'll need to purchase a registration code.

You can install both versions on your computer. The MDSolids Version 2.6 setup program should not disrupt your previous version from the Craig textbook (unless you override the suggested installation folder during the Setup routine).

   
Q:
Is MDSolids OLE-capable? Can it do drag and drop to Microsoft Applications like Word and Excel?
A:

MDSolids is not OLE-capable, but you can transfer text and data to these Microsoft Applications.

The explanations that are produced in many of the calculation routines is in Rich Text Format. You can paste this text into Word. To copy an explanation: (1) left-click and hold in the MDSolids explanation box, (2) drag the mouse to highlight the portion you want to copy, (3) hit Ctrl-C to copy the highlighted material to the clipboard, (4) in MS Word or similar application, hit Ctrl-V to paste the copied material into the document.

Data from the Stress-Strain Curve routine, the Section Properties module, and the General Analysis Module can be saved directly in Excel spreadsheet format (.xls).

   
Q:

Your zipped download of MDSolids is not a valid zip file - it is impossible to unzip it after downloading!

-or-

I just tried downloading your program, both the full program and the individual disks. In all cases, I obtain a shortened file that WinZip says is not a valid zip archive. There may be something wrong at your end or mine !

A:

Ahh, the joys of downloading software...

Downloading software is extremely convenient when it works properly, but it can be quite frustrating when it does not. In a typical download operation, there are many computer network connections that must be made. When downloading a relatively large file that takes a long time to transfer (like the MDSolids26.zip file at around 8.5 Meg), it's not uncommon that the connection gets interrupted at some point. Unfortunately, browsers don't tell you that the transfer was abnormally truncated.

If you run into problems opening the MDSolids setup file, it may be due to some problems that occurred during download. Compare the size of the downloaded file with the sizes posted on this website. If the downloaded file size differs from those sizes posted here, it's likely that the download operation was aborted prematurely. The only remedy is to try downloading again.

MDSolids 2.x is now available for purchase on CD. To purchase a CD with your registration, follow the DigiBuy link on the Purchase page. For delivery method, select CD.

   
Q:
How do you consider linear distributed loads in the beam diagrams?
A: This capability has been added to Version 2. You can also consider linearly distributed loads in the General Analysis Module. In the General Analysis Module for beams, you will have to specify a moment of inertia and an elastic modulus for the beam. If you are not interested in computing beam deflections, you can enter any non-zero positive value for these properties. (To enter the same values in all cells in the column, click on the heading cell.)
   
Q:
Can MDSolids handle statically indeterminate beams?
A: Statically indeterminate beams can be analyzed in the General Analysis Module. The user defines deflections and/or rotations at selected nodes to specify whatever support conditions are required. Deflections and rotations can be given a value of zero to model a perfectly rigid support, or a non-zero value can be specified to represent support settlements or rotations. The General Analysis Module can also be used to analyze statically determinate and indeterminate axial and torsion structures.
   
Q:
What does "MDSolids" stand for?
A: MDSolids is derived from Mechanics of Deformable Solids, a title sometimes associated with the mechanics of materials course.
   
Q:
Will MDSolids work with Microsoft Windows ME?
A: Although Several people and institutions are using MDSolids with Windows ME, and there have been no reports of problems.
   
Q:
Will MDSolids run on a network?
A: Several universities have successfully installed MDSolids on networks.
