    Selected remote point location is different from hit point location

    Hello, I am conducting a harmonic response analysis of a shaft. I put point masses for corresponding rotor parts to include mass and inertia effect. I applied "rotational velocity" in the modal analysis and "rotating force" under Harmonic response section. My problem is, during rotating force...

    Explicit analysis results and location differ according to mesh size

    Hello gents, I have run Explicit analysis simulating drop test. I used hex dominant method(mostly) to mesh and ran mesh refinement process to validate the results. Looking at the critical surface which hits to the ground i observed the highest stress values. Notewithstanding during decreasing...

    Which result is important after modal analysis; displacement or mode frequency convergence

    Hi there, I have run several modal analyzes on the same model with different mesh sizes. Eveery time, i change the mesh size (gradual decrease) i get different mode frequency and displacement. My questions to experienced users: 1. First of all, why do i get different frequency and displacement...

    Battery drop test in ANSYS

    Hello all, I would like to simulate real drop test in ANSYS environment for my batteries. Basically battery will exhibit "free fall"(no initial velocity) from 1,5 meter height to the concrete floor. My questions are: 1. Which analysis type i should prefer? Implicit/explicit or transient? 2...
