There are&#xd;&#xa;a myriad of solutions available in the marketplace for a number of different&#xd;&#xa;engineering and scientific applications, but it is not always easy to find the&#xd;&#xa;most appropriate solution for a particular circumstance, because many of the&#xd;&#xa;packages emanate from University research departments or Government development&#xd;&#xa;projects that do not have access to sufficient resources to publicize their&#xd;&#xa;products adequately. While the primary focus will be on numerical&#xd;&#xa;analysis solutions &#x28;FEA, CFD, Signal Processing, SPICE electronic simulation,&#xd;&#xa;etc.&#x29;, we will occasional touch on other aspects of CAE such as Computer-Aided&#xd;&#xa;Drafting &#x28;CAD&#x29;, 3D modeling, data acquisition &#x28;Test and Measurement, etc.&#x29;, and&#xd;&#xa;other such technologies that can add value to the engineering process.&#x3c;&#x2f;p&#x3e;]]></description><copyright>Copyright 2026</copyright><pubDate>Mon, 07 May 2012 13:00:00 EST</pubDate><generator>https&#x3a;&#x2f;&#x2f;cr4.globalspec.com</generator><item><title><![CDATA[OpenSource Rapid Prototyping &#x28;3D Printing&#x29;]]></title><link><![CDATA[https&#x3a;&#x2f;&#x2f;cr4.globalspec.com&#x2f;blogentry&#x2f;19791&#x2f;OpenSource-Rapid-Prototyping-3D-Printing&#x3f;from_rss&#x3d;1]]></link><description><![CDATA[From the RepRap&#xd; Wiki&#x3a;&#xa;&#xa;&#x22;The&#xd; RepRap&#xd; project is&#xd; an initiative to develop a 3D&#xd; printer&#xd; that&#xd; can print most of its own components...As an open&#xd; design,&#xd; all of the designs produced by the project are released under a free&#xd; software license...Due&#xd; to the self-replicating ability of the machine, au]]></description><pubDate>Mon, 07 May 2012 13&#x3a;00&#x3a;00 EST</pubDate><guid><![CDATA[https&#x3a;&#x2f;&#x2f;cr4.globalspec.com&#x2f;blogentry&#x2f;19791&#x2f;OpenSource-Rapid-Prototyping-3D-Printing]]></guid><dc:creator>cwarner7_11</dc:creator><dc:subject>OpenSource Solutions for Computer Aided Engineering</dc:subject></item><item><title><![CDATA[Hidden Treasures of Open Source Software]]></title><link><![CDATA[https&#x3a;&#x2f;&#x2f;cr4.globalspec.com&#x2f;blogentry&#x2f;17943&#x2f;Hidden-Treasures-of-Open-Source-Software&#x3f;from_rss&#x3d;1]]></link><description><![CDATA[While surfing about on the Internet the other day, I&#xd; came across a hidden treasure of Open Source code hiding in plain&#xd; sight, sponsored by the United States National Institute of Standards&#xd; and Technology.
