    basic contact problem for a beam model

    Dear all, I have a problem modeling a contact beam models. I am a beginning of the contact models. I attached a very simple model made by myself. Can anybody help me to check what is wrong with my model? Thank you very much for your time. Best Regards, Dovil FINISH /CLEAR,START *AFUN,RAD...

    ANSYS/LSDYNA time history variables HELP

    Dear Friends, I ran a drop test using the Drop Test Module in ANSYS/LSDYNA. But it seems like I can only read the time history of the displacements, velocities and accelerations for CG and Lowest Point. Does anyone know how I can read the time history data of DOF, Strains, Stress, etc., for...

    rebounded height is not correct (ansys/ls-dyna)

    Dear Friends, I have a problem when simulation a drop test in ANSYS/LS-DYNA. I was trying to drop a flat plate with linear elastic material properties, but the first rebound height is always as high as the original drop height, or even a little bit higher, but after two or three rebounds the...

    apply ansol for shell163

    Hello, I was trying to add time history of the nodal solution of strains for Shell163 elements. Then, I got such error message: The averaging done by the ANSOL command together with the RSYS,SOLU command assumes consistent coordinate systems for all elements used in the averaging. Shell...

    how to smooth the output variables in ANSYS/LS-DYNA

    Hi Drej, Thank you very much! I can use matlab to do it. You are right that I did not put any damping in my model, that might be the reason of the "noise". Thanks again.

    how to smooth the output variables in ANSYS/LS-DYNA

    Hello, Does anybody know how to smooth the output variables in ANSYS/LS-DYNA. I ran a drop test and got the acceleration of the gravity center, but the data contained a lot of noise, so I want to smooth the data. But I could not find any output variables in "Main Menu >TimeHist Postpro >Smooth...
