Direct transient dynamic analysis

Hello,

 

I want to perform a direct transient dynamic analysis. I’m following the steps of the Altair tutorial “OS-1310: Direct Transient Dynamic Analysis of a Bracket”. Now instead of 1 force that needs to be applied (as in the tutorial), I have 20 forces, each with x, y and z components. This means that I have 60 force components that all change differently in a period of 2 seconds.

 

I created 60 tabled1's to map the time component to these forces along with 60 Darea's (3 Darea's per force, one for each x, y and z component cause they have a different time tabled1). Now to connect each force to its own tabled1, I used Tload collectors but that means I have 60 of them as well.

 

Now the problem is that I don't really know how to put all these 60 Tloads together for 1 transient load step. Is there a possibility to put all Tloads in 1 collector maybe or is there a different way to approach this?

 

I found out that I can use a Dload card to combine all 60 Tloads but I don't know if this is the correct way to solve my problem.

 

Kind regards
