Advantage and Limitation of Simulation

Advantages and Disadvantages of Simulation

Simulations are computer models used to check the performance of a system in defined conditions. It accelerates the product design process. Therefore products comes to market faster at low development cost. In this article we will discuss advantages and disadvantages of simulation studies.

We suggest you to read this article on role of simulation in product design and development.

    Advantages Of Simulation

    Simulation offers various advantages. They have application in every field. But this article coves the advantages of simulation in mechanical design only.

    System Behavior Analysis

    Simulations helps in analyzing the behavior of a system without actually building it. Therefore engineers can work on alternative solutions to achieve desired results. Various design options are simulated and the best solution is selected for prototyping.

    Reduces Manufacturing Cost

    Simulation helps in designing first time right products. Therefore manufacturing and testing cost reduces significantly.

    Faster Products to Market

    With Simulation designers can reduce the number of design iterations. Therefore Design cycle time reduces significantly. This gives companies advantage of launching products in the market faster. 

    Design Analysis : Visual Output

    Simulation results are exported in visual outputs like graphs. That helps in analyzing system and product output performance.

    Problem Solving

    Simulations helps in analyzing a problem at various levels. This leads to faster and effective problem solving.

    Value Engineering

    Simulation studies helps in reducing manufacturing cost of existing and new products. For example mold-flow analysis is used to reduce injection molding cycle time.

    Disadvantages of Simulation studies

    Along with so many advantages simulation studies also have some disadvantages. But it is a fact. simulation disadvantages are very less compared to their advantages.
    Higher Initial Investment

    Simulation software has disadvantage of high initial investment. Therefore small companies can not afford it. These software are very costly and require high computing power. This Leads to higher system and software cost.

    Accurate Boundary conditions and input Data

    Accuracy of simulation output results depends on input data. System boundary conditions such as environmental temperature, pressure and material has to be defined accurately to achieve accurate results. These boundary conditions are difficult to predict.

    Not 100% Accurate

    Simulation software are not 100% accurate. You should expect some discrepancies in simulation results and tested product. With time engineers can refine their simulation results.


    To sum up, Simulation helps in reducing and eliminating design and manufacturing risks during initial design stage. It has their advantages and disadvantages but overall it adds value during new product development. Grey areas in design are identified with simulation.
