Hi,

Hey everyone,

I’m working on a harmonic analysis simulation and have a question about splitting the frequency range.

Let’s say the frequency range I’m analyzing is from 10 Hz to 100 Hz. Instead of running the harmonic simulation for the entire range in one go, is it feasible to split the range into smaller intervals, for example:

• One simulation for 10-50 Hz, and

• Another for 50-100 Hz?

I’m trying to understand if this approach would still provide accurate results or if there are any drawbacks, particularly at the boundaries where the ranges are split. Has anyone used this method in their analysis, and if so, were there any issues with accuracy or continuity?

From my understanding, harmonic analysis calculates the steady-state response at a specific frequency. For example, consider the system at 10 Hz, assuming no damping. We know the equation is:

M(x′′)+k(x)=Fsin⁡(ωt)M(x'') + k(x) = F \sin(\omega t)M(x′′)+k(x)=Fsin(ωt)

Since 10 Hz is the starting frequency, the initial displacement at all nodes would be zero, x(t)=0x(t) = 0x(t)=0. By solving this, we get the response for this frequency.

Now, when the solver moves to 11 Hz, will it assume the initial displacement is zero again, or will it consider the solution from the previous frequency?

I’d appreciate any insights or suggestions regarding the feasibility of splitting the frequency range and how solvers handle initial conditions between different frequencies.

AI for CAE

The question isn’t “if” but “how soon”

CAE, or Computer-Aided Engineering (CFD, FEA, FSI, and optimization), is a field that utilizes computer software and tools to deliver the design, analysis, and optimization of engineering systems and components. This field plays a crucial role in industries such as automotive, aerospace, manufacturing, and civil engineering, enabling engineers to make informed decisions and improve the efficiency and reliability of their designs.

With recent developments, seeing how AI (Artificial Intelligence – here I mean rather Machine Learning but only calling it AI to make things easier) is disrupting field by field, everything seems that AI will disrupt the CAE field too. In my humble opinion, it’s just a matter of time and the only question is when (and how exactly) it happens rather than if it happens.

We’re just somewhere at the beginning and it’s even very difficult to say what is going on at the moment – not a mention that it’s impossible to predict what will happen in the future. However, there are a couple of things that we CAN say. 

The thing is, the usual CAE workflow involves a bunch of easy manual tasks and decisions based on data. And AI seems to be perfect for lending a hand with all of that.

🌪️ Centrifugal pump CFD, FEA & FSI Simulation 🌪️

Centrifugal Pump is the hidden workhorse of mankind 🚀. Pumps transport water everywhere where it is needed 💧, and water distribution networks represent one of the largest infrastructure assets of industrial society 🏗️.

The global pump market is expected to grow significantly in the coming years 📈, due to the increasing demand from various end-user sectors, especially the agriculture sector 🌾. According to a report by Fortune Business Insights, the global centrifugal pump market size was USD 29.24 billion in 2020 💰 and is projected to grow from USD 30.56 billion in 2021 to USD 45.56 billion by 2028 📊, exhibiting a CAGR of 5.9% during the forecast period from 2021–2028 📆. Another report by MarketsandMarkets estimates that the global centrifugal pump market will grow from USD 39.7 billion in 2023 to USD 51.5 billion by 2028 🌍, recording a CAGR of 5.4% during the forecast period.

The big issue is that most of the pumps are used in regimes that are far away from their best efficiency points 🤷‍♂️. In total, that leads to wasting huge amounts of electrical energy 💡 which is more than 90% of the total costs of pump ownership 💸. Take a look at how to make a comprehensive CFD, FEA & FSI Simulation of a centrifugal pump by TCAE, to optimize the centrifugal pump efficiency 🚀.

Kaplan Turbine CFD, FEA, FSI, and Optimization

CFD (Computational Fluid Dynamics), FEA (Finite Element Analysis), and FSI (Fluid-Structure Interaction) simulations are powerful tools for analyzing the performance of hydro turbines.

CFD simulations can be used to predict the fluid flow and pressure patterns in and around a hydro turbine, including the water flows through the turbine blades, the pressure drop across the turbine, and the efficiency of the turbine under different operating conditions.

FEA simulations can be used to analyze the structural integrity of the hydro turbine and its components, including the blades, shafts, and bearings. These simulations can help to identify potential stress and fatigue issues in the turbine and to optimize the design of the turbine for better performance and durability.

FSI simulations can be used to simulate the interaction between the fluid flow and the turbine's structure, which is especially important in hydro turbines because of the large loads and pressures that are generated by the water flow. FSI simulations can help to understand how the turbine's structure deforms and how it affects the fluid flow, as well as how the fluid flow affects the turbine's structure.

Altogether, CFD, FEA, and FSI simulations can provide a comprehensive analysis of a hydro turbine's performance, including its efficiency, structural integrity, and durability, which can be used to optimize its design and improve its performance.
