In all versions of SOLIDWORKS Simulation, Remote Loads can be created using two connection types: Rigid and Distributed. Now with Simulation 2020, we can use these same two options with Bolt and Pin connectors as well. To see the difference between these options, I’ve run a few comparison studies to illustrate what they are doing. Can you tell the difference between these two stress plots?
New in SOLIDWORKS Simulation 2020 it is possible to define Draft Quality mesh elements or High Quality mesh elements for each individual solid body in the simulation study creating a hybrid mesh. This new capability will be helpful in saving your meshing resources. It gives you more control on which solid body you can apply either a Draft or High Quality element type too.

SOLIDWORKS Simulation has been around for years, tracing its roots back to 1982 and the Structural Research and Analysis Corporation (SRAC).  SOLIDWORKS Simulation used to be called COSMOSWorks, and since its early days, the Finite Element Analysis program has strived to be powerful, accurate, and EASY to use.

In theory, saving and loading SOLIDWORKS Simulation results to a network location is possible and, if it works, can make life easier for the person running a Simulation analysis. The problem is that conditions have to be just right for it to work properly. The network has to be very fast, the result files must be small, the network's anti-virus cannot block the simulation data as it is created and transferred onto the network. 

 

 

A little-known but powerful tool in SOLIDWORKS Simulation is the Compare Results Tool. In recent years it has been updated and is a powerful way to visually compare simulation results between simulation studies not only in one SOLIDWORKS configuration but multiple configurations. There is an upper limit of four studies that can be seen at any one time, however. 

SOLIDWORKS Simulation is commonly used on a model with a combination of fixtures and known force loads to find displacement and stress data from such loading conditions. At times though, it is not known what applied force to place on a model whereas the displacement of the model is known and the applied force is the desired quantity to be measured.
The use of sheet metal bodies in SOLIDWORKS Simulation provides a streamlined study setup workflow. The nature of sheet metal geometry leads to the utilization of shell elements to represent their shape in a simulation study. The use of solid elements is prohibitive due to the large aspect ratio difference between the span and thickness of sheet metal bodies. Their usage would lead to very large mesh size and corresponding computational effort.

SOLIDWORKS Simulation will automatically create beam joints when you create a study with parts created with weldments, or if you treat a solid body as a beam inside of your analysis.

Shell elements are very useful and can make your SOLIDWORKS Simulation analysis run faster and more accurately than if solid elements were used in certain situations. These situations are when the model has a very large surface area when compared to the thickness. The general rule of thumb is a 10 to 1 ratio of surface area to thickness of a model.
