    Flow 2D Parametric Sweep

    1. Analyst Simulation Guides
    2. Flow

    In this example we will demonstrate how to set up a parametric sweep, we simulate a 2D flowmeter example with different flow velocities to see how this changes the signal recorded at the receiver....

    3. Question about velocity input signal

    Hi Hyunjae, Yes so if you want to use a pressure load the way you have set it up looks fine but if you want to load the same area as the velocity load you will have to add  sdf2 pld1 vct1 vacm wate...

    TOFD 2D

    1. Analyst Simulation Guides
    2. Time of Flight Diffraction

    This is a modelling guide to help you get started simulating Time of Flight Diffraction (TOFD) systems in OnScale. In this initial example you will be shown how to get the impedance of a basic 2D T...

    3. Question about velocity input signal

    Hi Hyunjae, So yes Chloe is right you would define the velocity load using BOUN DEFN and NODE like this: boun      defn velocityload vel func       node $i2 $i4 $j2 $j2 This will not change any of ...

    3. PZFlex can not insert complex geometry parts

    Hi Xuan, So just so I'm clear - you are trying to import the geometry into PZFlex and this is where you are seeing the importation problems?  If this is the case the last update of PZFlex 2018 was ...
