    Piezoelectric Actuator Position Constraint

    Hey, I am trying to mount a piezoelectric actuator(PZT) on a plate. The PZT is rectangular and I have created a tie constraint between a surface on the bar and one of the PZT's surfaces. How do I put the PZT at a certain location on the bar in the assembly? I am assigning a coincident point...

    Abaqus Simulation Run Time

    Hey all, I am running a wave propagation simulation on Abaqus that requires a large number of element and a very small time step(increment). I am using the Dynamic Implicit analysis type. When I run the simulation ,it take a very long time. I even tried using a faster computer(32 GB of RAM) but...

    Mesh and Increment Size-Lamb Wave Propagation Simulation

    Hey all, I am simulating Lamb wave propagation in a plate and was wondering if anyone knows where I can find the criteria to chose the mesh size and the time increment size. Thank you. Regards,

    Electric Potential B.C. in the Dynamic/Explicit Step

    Hey all, I am trying to apply an Electric Potential B.C. to a surface. I want to use the dynamic/explicit analysis type, however, when I select that as my step type, the Electric Potential B.C. option disappears from the edit B.C. window! Is that due to a license limitation or an error I might...

    Step Type-Ultrasonic Simulation

    Hey all, I am trying to simulate ultrasonic waves(Lamb waves) in a plate. I was wondering what type of step analysis I should use. I am currently using the static/general step but I am not getting good results. Also, what is the difference between the different steps? I have also tried to run...

    Lamb wave generation in bars and plates

    Hello! I am trying to generate acoustic waves in aluminum bars and plates to simulate an experiment we are performing in the lab. We use piezoelectric actuators to generate and receive the waves in the lab. I know that similar simulations have been done in Abaqus, however, I an having...
