Reply To: Transient structural Impact analysis

Hi Erik,

Thanks for the method suggested, i tried this method and did not work to solve the issue.

To identify the problem i have prepared a simple case of a block hanging from a wall, just want to check the stresses due to self weight of the object in transient analysis

in this model i have not given any dynamic loading except for the gravity acting downwards, i have identified that at 0.000032996 sec with time integration OFF the result is same that of a static structural results regardless of time we specify.

but when i introduce the 2nd step without any dynamic load and increased time 0.001sec with time integration ON, so the results should be same as first step results right? but unfortunately the stresses and deformation gets increased drastically, this behaviour is not true in actual

what could be the solution to get the same stresses and deformation under gravity loading in both steps, because gravity wont increase with time in real life, so how to make the results (due to gravity) constant in all load steps?

FYI - i tried supressing gravity in 2nd load step but did not work.
