How to make the Perfect Golf Putt using SOLIDWORKS Motion [VIDEO]

This summer I’ve realized that my short game could use some work so I thought I’d take some pointers from SOLIDWORKS Motion.  With the use of Motion linked with a Design Study, SOLIDWORKS can automatically calculate the speed and direction required for that perfect golf putt. Here is the…

New in SOLIDWORKS Simulation 2015 – Run Specified Studies

SOLIDWORKS Simulation 2015 has introduced a new option to Run Specified Studies within a file so you have an option to choose what you want to run.  Previously you could run the active study or all studies in the model.  This will allow you to setup…

SOLIDWORKS Simulation Accuracy (?)

A common concern I hear when presenting SOLIDWORKS Simulation is whether or not the results are accurate. This is a difficult – if not impossible – thing to prove without empirical data to back up the results. To reassure those concerned, I usually rely upon the…

Happy New Year from the Javelin Simulation Team

It has been an exciting year for SOLIDWORKS Simulation, and, as always, we’ve seen some incredible changes happen to the software. The biggest change in the last year has to be the release of a new package of simulation tools: Simulation Standard. This is a great…

When to use Nonlinear Analysis?

A Linear Static analysis can be performed on a problem if the following assumptions are valid: The material is linear elastic, where the geometry will return to its original shape if the load is removed. Deformations are small in relation to the dimensions of the…

SolidWorks Simulation Database Files Description

For SolidWorks Simulation Files, the results are contained in one file with the extension CWR. Other information like study properties, materials, restraints, loads, and contact conditions are saved, in the SolidWorks part or assembly document. Many files are created by the solver during an analysis. Some of them are temporary files automatically deleted when the analysis is complete, others are result files which are meant to be put together and saved in the CWR file before being deleted when the model is closed. In case of abrupt termination of the solver or of SolidWorks, the deletion of the files will not take place, leaving many unnecessary files behind. They can be deleted manually, as only the CWR file is required to access the mesh and results. SolidWorks…

Simulation: Factor of Safety Plots – Highlighting the Areas of Concern

The default Factor of Safety (FOS) plot would show the distribution of values over the entire model with a colour chart.  Typically you would modify the colour chart to have the Minimum value as your required FOS.  The regions in red are the areas of…

SolidWorks: Animating a 6DOF Robot from Point to Point [VIDEO]

Suppose you need to make an animation of a 6 degree-of-freedom robot. However you only need to show the end-effector moving from point A to point B to point C, etc. You aren’t concerned with the movement of each joint at the moment. Have you ever tried free-dragging something with six degrees of freedom? I guarantee you will have it flipping around and inverting due to the fact that there are too many positions and orientations possible. As you are looking at a 2-dimensional screen, the robot could be at any depth; and it’s also possible to satisfy the position with the joints inverted. So how would you go about animating this robot? You could run some inverse kinematics to determine each joint position required for the…

Don’t Settle for Anything Less with Mirrored Results about Planes of Symmetry in SolidWorks Simulation 2014 [VIDEO]

We have all used symmetry to boost our simulation times, whether it be planar or cyclic and were happy to have achieved the results in a short time, only to be told by the manager to run the simulation for the full model so it makes more sense to him and to the customers. Here is a new feature in SolidWorks 2014 which will keep both you and your boss happy. You now have the option to apply the symmetry for the analysis and the software will mirror the results for you and show you the results in the entire model. These new results will actually serve as a double check for the symmetry assumptions that made. In the PropertyManager of the desired result quantity,…
