Now in the example model that I am making available to download from here, I used the No Penetration contact types between the parts. So in the end, (a) you donвЂ™t get bothered with a message telling you that bodies are interfering (b) the model meshes successfully and (c) you are able to get good valid results with the interaction between the parts that you would expect. Image 5: Defining Local Contact sets automagically. Once added, the set is removed from the list so that you can define others differently, if needed. Shift+select all or Ctrl+select individual sets with the Type of contact that you want to define and then click the green Add button to add them to your simulation tree. Then after finding the sets, you can click on each pair of faces that the automatic detection finds to visualize the faces in the graphics window. You can select the bodies to find pairs of faces that fit the criteria in the options note that can also make quick work of this by window selecting all bodies and/or components. I recommend, when possible, to use the option to Automatically find contact sets, as shown in Image 5 below, even within gap tolerances if the faces are not touching. In either case, you will now need to define Local Contact sets in order to define how the bodies are interacting with one another. Image 4: Redefine the Global Component Contact type. I think that you could also just delete the Component Contact from the tree altogether, essentially making it to вЂњallow penetrationвЂќ or also known as free. What is needed is to change the Global Component Contact setting to either Allow Penetration or No Penetration, as in the image 4 below. So this is a good thing! But I havenвЂ™t yet shown you how work around this geometry, ahem, meshing issue. So SOLIDWORKS Simulation uses the Interference Detection tool on the CAD side of the house as a way to help prevent you from creating bad meshes. When the faces are just touching, this scenario is desired, but when bodies are interfering, you could collapse two nodes that shouldnвЂ™t be and it can create some gnarly looking elements (with bad shape functions) that you donвЂ™t want to put into a finite-element solver. When the Global Contact is defined as Bonded, then the meshing process will search for nodes from adjacent bodies now and try to collapse nodes that are close enough within the tolerance that you defined (or by default) in the mesh settings. In the next step of a Solid mesh, it knits all the surfaces together at the nodes that are overlapping from adjacent surfaces to create a water-tight solid and then a different volume-filling mesher fills it in. ItвЂ™s interesting to note here that for a Shell mesh type, the meshing process stops here but not for a Solid mesh. In brief, the meshing process starts first by evaluating and meshing each surface of a body separately. Image 3: Bonded global contact is the culprit.

A blog post maybe for another time.) To understand why the Global Bonded contact is the culprit in this case, you have to know a little bit more about the meshing process behind the scenes inside the software. (I contend that SOLIDWORKS is the best pre-processor for FEA out on the market. Typically the model geometry presented for a simulation is not be purpose-built for FEA but designed for another purpose, such as manufacturing. The problem isnвЂ™t really with the geometry, but with the default Global Contact condition set to Bonded.

Well, read on if you want to find out how to fix this situation in SOLIDWORKS Simulation without having to modify the geometry. So you click to view the interfering bodies, such as in Image 2 below, and now in this case you wish that you could simply hit the вЂњIgnoreвЂќ button and for it to all go away. Agghhh!ДЄnd IвЂ™m pretty sure that you have, so as you know it can be really frustrating. Image 1: Detected bodies that are interfering. If youвЂ™ve ever run into the case where you get the following message, seen below in Image 1: вЂњAt least two bodies are interfering.
