SimSolid

About SimSolid
SimSolid can analyze complex parts and large assemblies not practical with traditional FEA and do it efficiently on a desktop class computer. Both fast and accurate, SimSolid controls solution accuracy using a unique multi-pass adaptive analysis.The computational engine is based on breakthrough extensions to the theory of external approximations. External approximations are a generalization of Finite Element Method (FEM) in terms that:
• Absolutely arbitrary geometrical shapes can be used as “finite elements”
• Basis functions which approximate field of interest in the part volume can be of arbitrary class and are independent of the volume shape
SimSolid does not use the point-wise degrees of freedom (DOF) inherent in traditional FEA.
Key benefits of SimSolid
Eliminate Geometry Simplification and Meshing:
SimSolid’s unique technology completely eliminates geometry simplification and meshing, the two most time consuming, expertise extensive and error prone tasks
done in traditional FEA. With SimSolid, model preparation is done in minutes.
Analyze Complex Parts and Large Assemblies:
SimSolid has been designed to analyze complex parts and large assemblies not practical with traditional FEA. SimSolid is tolerant of imprecise geometry. Its assembly
connections are industry best at handling ragged contact surfaces with both gaps and overlapping geometry.
Advanced Automation Workflows:
SimSolid has intelligent workflows that let you create complex connections—spot welds, seam welds, bolted joints, adhesives and more—in minutes. These workflows reduce or entirely eliminate the model setup time when working with multiple design variants.
When importing a new design variant, SimSolid automatically maps materials, connections, loads and boundary conditions.
The software also allows the mapping of loads from an external file.
Rapid Design Feedback:
SimSolid is fast, real fast. Solution times are typically measured in seconds to minutes on a standard PC. With SimSolid, multiple design scenarios can be quickly
analyzed and compared. And, accuracy can be specified on an individual part level allowing a rapid drill down to any level of detail that is required.

Lots of functionality!
Reviewed on 2024/02/23
Pros
I like the non-linear analysis that SimSolid allows.
Cons
There is no easy way to transition from Solidworks Simulation. Seeing what materials are applied takes too many clicks.

Pros
Easy to use geometrically model without mesh. Easy to use local 9n laptop for complex models.
Cons
Should be added something related by explicit analysis, but I guess Is not easy. And perhaps in future something related by an interface with a deep learning model.

I use SIMSOLID to simulate various mechanisms.
I do linear, non-linear and modal analysis but the software has over capacities (dynamics and thermal).
The mechanisms I work on are complex with a lot of contact between the parts.
I can obtain results after few clicks and few minutes, this allows me to test a maximum of solutions in a very short time.
Pros
Possibility to import natif CAD format.
Type of analyzes that can be performed: linear, non-linear (geometry, materials, contact), modal, dynamic and thermal.
It is possible to automatically create weld beads , to detect contacts and to detect scews/bolts.
The software is always update with new features.
The support can easily be reached
Cons
You can't modify for the moment the CAD in SIMSOLID interface.
The import of CAD is a little bit long

With the right care, it's a huge time saver and a great way to enter simulation
Reviewed on 2024/02/23
Pros
It can take the full CAD, right down to the nuts and bolts, and use it add more detail to the analysis. It has a great range of features from linear static to modal and more. I like the the feature where simulations setups can be copied over to new version of the design automatically
Cons
It seems simple but there are some key settings you have to get right in order to get sensible results. Sometimes habdling the number of contacts and joints in an assembly is unwieldy.
