Efficiency, Savings and Accuracy by Proper Modeling

Johnson Engineering & Design has been modeling products since 1997. Designs in CAD (Computer-Aided Design) are used to create 3D modeling and simulation of products or 'parts' or even entire assemblies, which are then used as a basis for CAE (Computer-Aided Engineering) simulations. However, the geometry of CAD models can be very complex, and this can cause problems when using them for CAE analysis.

Here are a few reasons why having us properly simplify your CAD geometry is important for accurate CAE analysis:

Simulation accuracy: Complex geometry can slow down simulations, and in some cases, it can even cause the simulation to fail altogether. By simplifying the geometry, the simulation can be performed more quickly and accurately, allowing for better results.
Meshing: CAD models with complex geometry can be difficult to mesh, which is the process of dividing the model into smaller elements for analysis. If the model is not properly meshed, it can lead to inaccurate results or even simulation failure. Simplifying the geometry can make it easier to mesh, which can improve the accuracy of the simulation.
Time and cost savings: Simplifying CAD geometry can also save time and money in the CAE analysis process. By reducing the complexity of the model, it can be analyzed more quickly, which can reduce the overall time and cost of the project.
Interpretation of results: Simplified geometry can also make it easier to interpret the results of the simulation. When a model is too complex, it can be difficult to determine which parts of the geometry are responsible for specific results. By simplifying the model, it is easier to see how changes in the geometry affect the results of the simulation.

Overall, properly simplifying CAD geometry is crucial for accurate and efficient CAE analysis. By doing so, JD&E can improve the accuracy of our simulations, reduce the time and cost of your projects, and make it easier to interpret the results.

Engineering prestressed concrete structures can be challenging for several reasons:

Complex Design: The design of prestressed concrete structures is more complex than that of conventional reinforced concrete structures. It involves determining the appropriate level of prestressing force and the location and number of prestressing tendons to achieve the desired structural performance.
High Precision: Prestressing requires a high degree of precision in the fabrication and installation of the prestressing tendons. Even small errors in placement or tensioning can lead to significant changes in the behavior of the structure.
Risk of Failure: Prestressed concrete structures are susceptible to failure due to a variety of factors, including corrosion of the prestressing tendons, anchorages, or other components. Any failure in the prestressing system can result in a catastrophic collapse.
Maintenance: The maintenance of prestressed concrete structures is also more complex than that of conventional reinforced concrete structures. The prestressing tendons and anchorages require regular inspection and maintenance to ensure their continued performance.
