Status code: 9 MATRIX_Singular_OR_INDEFINITE

Some error messages make you wonder, what does it take to get something simple done? I have often wondered how coders come up with names for errors and claim them to be logical? One common bane is “Status code 9." This message is often followed by a second message claiming there aren’t enough restrains defined. Basically, the software cannot figure out how parts are interacting in 3D space. Every solid or surface body has six degrees of freedom available to it (three translational and three rotational). When users define loads and restraints they remove degrees of freedom from the model.  Behind the scenes (in SolidWorks) equations are being written to

Drawing Views of Individual Bodies

I have recently had a few Technical Support questions regarding how to create drawing views of individual bodies from within a weldment. This is actually very simple and can be completed by using the little known command Relative View.€ While in a drawing, go to €œInsert, Drawing View, Relative to Model€ Select the face of a body in your drawing view. SolidWorks will then switch you to the model where you have the option to choose the €œScope and select €œSelected Bodies€. Select the body you want to detail. For orientation, select a First Orientation€ and a €œSecond Orientation€. Click €œOK€ and the drawing document window will appear. Based on

YouTube COSMOS Tutorials

If you have trouble using COSMOS, just go to www.youtube.com and look up cosmos tutorials.  They have a lot of videos that explain certain types of analysis.  It is not in-depth knowledge on why it works the way it does but it can provide step-by-step instructions on how to create certain studies.  For instance, understanding airflow through a centrifugal pump: http://video.google.com/videosearch?q=solidworks&rls=com.microsoft:en-us:IE-SearchBox&ie=UTF-8&oe=UTF8&sourceid=ie7&rlz=1I7ADBS&um=1&sa=N&tab=wv&oi=property_suggestions&resnum=0&ct=property-revision&cd=1#q=solidworks%20simulation This is just one of the analysis tools that are available for viewing.  They do have other analysis packages that have been recorded so just search through the website.

Do your Designs Sing?

We often consider design to be safe if prototypes work out fine, or if over a period of time legacy data has paved the way. If comfortable with analysis, static tests are the first line of defense to prove concepts. Knowing loading conditions, and component interaction with its environment we identify success with an appeasing color chart of blue and green colors. Could it be we missed a few nuances making our best design not perform as planned? Let me clarify…. As you’re cruising along in your ride there is a sudden noise that always occurs at a certain speed. It goes away as soon as you cross that speed.

Instant 3D Tool

Are you seeing a preview like this when you try to edit a sketch? Click to enlarge picture If so, you may have your Instant 3D tool turned on. This is a new feature to SolidWorks 2008 and many people have been confused as to why they are not able to dimension properly or select certain things when editing a sketch. Instant 3D is a great tool, but in certain cases it can cause you to not be able to select or dimension properly when editing a sketch. Here is how to turn it off: first, make sure your toolbars are in ‘command manager’ mode. Your toolbars should look like

Help with Help Files

We often tend to look up help in our software for information that either isn’t intuitive or that we are confused about. But more often than not we have to access the software itself to get to the help menu. Wouldn’t it be nice to have help at your beck and call as it should be? You can have the help menu show up in Start \ All Programs menu \ SolidWorks 2008 \ Help Click to enlarge picture To do this: 1. Browse to C:\Documents and Settings\” user name on machine ”\Start Menu\Programs\2. Right click and create a new folder called “Help”3. In this folder create a shortcut to the help

Central Indiana SolidWorks User Group

Do you get excited about SolidWorks and its capabilities? Do you want to meet other individuals who feel the same way? Then come to the Central Indiana SolidWorks User Group! Meet users from all different industries and expand your knowledge of SolidWorks. The group meets every other month, and presentations are given in an open forum to share new ideas and functionality with SolidWorks and related products. Computer Aided Technology has been involved with this group for many years, and I will actually be presenting on eDrawings at the next meeting. Next Meeting- When: Thursday, July 17th Where: GT South Rib House 4919 S. Emerson Avenue Indianapolis, IN (Beech Grove)

Do you need a slam dunk test?

Static studies assume loads are constant or applied very slowly until they reach their full values. Because of this assumption, velocity and acceleration of each particle of model is assumed zero. As a result, static studies neglect inertial and damping forces. For many practical cases, loads are not applied slowly or they change with time or frequency. For such cases we use a dynamic study. The software calculates response of model by accumulating the contribution of each mode to loading environment. In most cases, only lower modes contribute significantly to the response. The contribution of a mode depends on load’s frequency content, magnitude, direction, duration and location. To test the

SolidWorks World 2009 Call for Papers

As everyone may or may not know SolidWorks holds a user conference every year and it has come time once again for SolidWorks to ask it users to submit ideas for presentations for the upcoming SolidWorks World. So the questions that arise are Where in the world is SolidWorks World, When is SWW, What is SWW, Why is SW looking for presentation ideas & How is it going to benefit me if I submit a presentation idea? Where in the world is SolidWorks World? Every year SolidWorks World is in a different location. This year it is in Orlando, Florida. Past locations have included Las Vegas, San Diego, and New

Do you need a specific type of machine to run Analysis?

Well the question cannot be answered without understanding what is it being utilized for? Depending on the type of analysis versus size of analysis problem; the range could vary significantly. In this link I will try to give an over view of what should be considered. RAM Having a lot of RAM on your machine is like having a vehicle with a lot of Horse Power. The difficult the terrain the stronger the engine should be. In SolidWorks and COSMOS world that means solving large and complex problems. Two gigs of RAM is adequate for solving linear analysis on small assemblies. As you go higher up the chain, from frequency
