Dassault Systemes offers SOLIDWORKS, a computer-aided design (CAD) system for education and manufacturing supporting 2D or 3D design, electrical design, simulations, and product development with collaboration tools.
It appears to be evolving more towards large users with the 3D EXPERIENCE, while becoming less focused on small users like me, becoming more expensive and limiting the number of cores while most PC's now can easily run 8 cores. Of course it is great for non-linear and highly non-linear scenarios, and especially good at combing a huge variety of element types. I guess it is not best suited for linear analysis due to its high price, but even in this case you have to put in the balance the ability to make the best choice of finite elements and being so straightforward about actually using them.
As a mechanical engineer, it is one of the best tools to just start modeling and engineering with. The UI tools are intuitive and engineering analysis such Mold Analysis, FEA, are great! Other 3D CAD modeling tools have a longer learning curve to master. All in all, if you're not planning to design an entire airplane with large assembly files, then Solidworks is your tool!
Create and modify designs from within the CAE environment. Although it has very basic capabilities, it is quite capable of generating 2D and 3D parametric designs. I have even generated some "fancy" designs which ended up being a challenge for draftsmen in specialized solid modeling CAD. I also like the fact that being somewhat limited, it forces you to stick to simple and effective design.
Addressing structural instabilities such as snap-through or buckling. This was such a challenge when I started using Abaqus, I had to take a course on "achieving convergence". Coming from there, I can see how SIMULIA has become increasingly able to give you the numerical tools or tricks you need to achieve convergence consistently. In the past I often feared running into different convergence issues as I moved across different produce sizes, leading to changes in the analysis approach, which would make it more difficult to compare them. I just went through a 12-size family in 5 dimensional scenarios each, without a single issue after ensuring convergence with the first couple of sizes.
Beautiful pictures. The post-processing of results enables me to generate highly illustrative, fairly easy to understand and elegant presentations, by controlling transparency and results shown independently on different groups, which I can select by material, location, etc.
The collaborative work environment is a cool and useful feature where groups of people can work on the same model at the same time, and SOLIDWORKS ensures that you don't overwrite each other's work.
The ease and amount of customization options are very useful for creating a personalized and intuitive user interface, whether SOLIDWORKS is your native CAD package or not.
It is very easy to quickly edit a model you have already created. The software allows sketch and feature editing without having to take the time to actually enter the sketch/feature environment.
The use of configurations and configurations-specific dimensions in the same sketch is very useful for creating different forms of the same part
Exporting sketches. For example, you can import dxf for sketches, but you can't export dxf. This is a major drawback for me, because I often communicate with customers through dwg or dxf sketches. If I can't export dxf, my sketches in CAE are "dead". I have to redo them in the dwg sketch. It is so inconvenient, I often end up making the sketches in DraftSight, so I can export them to CAE but I still have the originals in dwg format.
CAE doesn't remember element type assignment by sets. Sometimes when I reconfigure or modify a design, I regenerate sets and surfaces, and this in turn updates material assignments, interactions and loads almost automatically. This doesn't happen with element types, so I often end up submitting a job with the wrong element types.
Mesh regeneration and re-mapping in 2D within the job. I need this a lot to model axisymmetric assemblies with sharp indentation the destroys the original mesh. I had it in MSC/MARC and it worked great. Abaqus has it only for 3D. I have tried alternatives like lagrangian/eulerian and eulerian domains but it's still more complicated.
Save DWG 2D files in inches or metric easily, defaults to metric and has to be manually converted to inches
When using the sketch feature, the ability to disable ALL references. If I don't know the exact shape and I want to draw/adapt my design, it harshly interprets the references which have no value to me. The easiest exact is to think about when you have a Microsoft Word document that has a lot of formatting, photos, tabs, etc. If you accidentally hit the "enter" key, you can explode the formatting and everything goes crazy. SW does this to me, I just want to "doodle" my sketches, edit/delete/etc and not be bound by arbitrary references.
For the sketch feature, ability to use a DraftSight plugin of some sort. I'm super fast in DS, if I could draw using the commands in SW then I would probably never open DS again and convert to SW full time. Currently, I only use SW as a way to convert 3D files so I can build everything in DraftSight.
Extremely well organized and friendly, reflecting the latest approaches in solid modeling and adding the FEA part so seamlessly for the user. It's a joy to use. I'm aware some people would complain about the meshing capabilities and thus prefer using HYPERMESH. Fortunately not my case. I did wish I had HYPERMESH a couple of times, but for most of my projects CAE meshing is fine.
I keep getting the feeling that it is drifting away from small users. I don't feel so comfortable with the SWYM community approach. I felt much better when you could just email or call HKS and you would feel like you were talking to a real expert who understood your situation. When I was reassigned to reseller in Argentina, which is like the other side of the world for me, I appreciated the cultural closeness, but I had to say goodbye to the level of support I had from HKS and learned to "support myself."
We have an unusual arrangement. We don’t pay for support, but we’re partnered with a VAR for second-tier support.
I work with other users if I have questions but when we’ve had to ask the VAR, they always have answers. It appears that all of the VARs have access to a support platform from DS SOLIDWORKS that helps them answer most questions.
MARC can do the job from an FEA point of view. It even appears better at a couple of things such as 2D remeshing and surviving with highly distorted meshes. So I regard it as a very competitive alternative. I prefer SIMULIA because the GUI is so much better, especially the ability to create actual parametric designs in CAE. ANSYS doesn't cut it for me. I tried it for 1 month and I would see how much I would struggle with convergence in large deformation and large displacement situations with hyperelastic materials with which I have to deal all the time. Also the GUI is not as well built an integrated as in SIMULIA.
Onshape is a direct competitor. It has great entry level pricing and it is easy to access with no installation required. Being a web based app there is sometime some lag being based in NZ. Management also have concerns over where the data is stored on the cloud. With SW we can control where it is stored
I don't even bother doing an ROI. Without SIMULIA I would be pretty much out of business. Except for the fact that I could still have an alternative with MSC/MARC.
Price is becoming a more difficult hurdle for small users. It appears I have survived because there was a 50% discount on my small 6-token package. Without this special price I would have to close my business. I'm currently exploring alternatives.
A more flexible scheme enabling to add tokens over short periods of time or paying per use could be an interesting possibility.
