CAD model Your model is not meshed properly or the mesher cannot even complete the meshing? This kind of problem happens to everyone, even the most skilled in FEA. Nowadays, CAD models tend to have too many details and so it is difficult for an analyst to simplify those models enough to get a proper […]
When do you actually need Simulation is product design?
product design FEA can be used mainly in 3 ways in product design: – As a tool for designers to help to create the right design -As a tool to check the design -As a tool to check the reasons why a product fails Designing a product is a challenge Designing a product is not […]
How to face a singularity error?
If you ever started to do linear static FEA Analysis, you probably encountered the following singularity error: ERROR [2007]: FACTORIZATION FAILED DUE TO A SINGULARITY AT TRANSLATION-X OF NODE 111 (RANK=5262) What is the cause of this singularity error? This error is generated when matrix decomposition cannot progress any further due to the presence of singularities. […]
What is stress? Explanation with images
Stress Let’s start with something simple. Let’s visualize a pressure applied on an object. The pressure is causing a certain deformation to your object. After I applied the pressure, what is happening inside the object? Let’s assume the object is composed of a lot of smaller cubes. What is actually happening to one of the small […]
Pushover Analysis Tutorial with midas GEN as per Eurocode 8
Pushover analysis is one of the performance-based design methods, recently attracting practicing structural engineers engaged in the field of seismic design. The objective of a performance-based design is achieved after the owner and the designer collectively select a target performance for the structure in question. The engineer carries out the conventional design and subsequently performs […]
Reinforced concrete building Design Tutorial in midas GEN
This example problem is meant to demonstrate the design of a Reinforced Concrete building structure subjected to floor loads, wind loads and seismic loads. Seismic Design Data – Dual system (special reinforced concrete structural walls with special moment frame) in the transverse direction – Special moment frame in the longitudinal direction – Assigned to a […]
