    Hi Hyunjae,   Your simulation time is only 0.6666667E-04 which is why only the first 0.65e-4s of your function was initially used. Scaling the time is going to change your input signal frequency. I...

    Hi Hyunjae,   How long are you running your simulation for? If you can you send your model files to support@onscale.com and we will take a closer look for you.   Thanks, Jeff

    Shear Waves

    Shear waves are sound waves where the displacement of the material are at right angles to the direction of wave propagation. These types of waves are also known as transverse waves and are only gen...

    Displacement

    Displacement is a measure of the change in position of an object. Often we will calculate the node displacement during a simulation to identify how a single point or a surface moves due to the forc...

    Explicit Solver

    Explicit is a type of FEA solver used to solve the differential equations. In an explicit solver, the nodes are effectively 'de-coupled' from each other. This makes the explicit solver ideally suit...

    Implicit Solver

    Implicit is a type of FEA solver used to solve the differential equations. An implicit method calculates the solution using the current system state and the system state at a later time. This means...

    Longitudinal Waves

    Longitudinal waves are sound waves where the displacement of the medium occurs in the same direction as the direction of the wave. These types of waves are also known as compressional or pressure w...

    X, Y, Z

    In a 3D coordinate system a point P is referred to by three real numbers (ccordinates) indicating the positions of the perpendicular projections from the axes which intersect at the origin. These a...

    Young's Modulus

    Young's Modulus (also known as the modulus of elasticity E) is the numerical value which defines the stiffness of a material measured in Newtons per square meter. Young's Modulus is a measure of ho...
