How to add standard earth gravity in msup transient system?

[peteroznewman]

You already have an acceleration load. Just add the acceleration due to gravity to that load.

Hello Peteroznewman sir,

 

I have one doubt, suppose I open static structural module and apply line pressure on a beam and then link transient structure module with static structure and apply acceleration over the beam. Then will the line pressure get overlap in transient structure module as well?

 

[peteroznewman]

No.

Just use Transient Structural, but use 3 time steps and turn off Time Integration in the first step when you apply the acceleration due to gravity.

The transient load is applied in step 3 with Time Integration turned on.

Here are more detailed instructions.

By going through your previous suggestions on another post of mine I tried working on perforated steel beam of I section using mid-surfacing but when I did modal analysis on that model the natural frequency of all the modes came out to be zero. Can you explain the reason?

[peteroznewman]

You didn't add a Fixed Support to one end of the beam in Modal, which needs its own support unless you link the Solution cell of a Static Structural into the Setup cell of Modal in Workbench, then you are not allowed to add a Fixed Support to Modal.
