help about Ansys UPFs development
 

Hi,

I am begin to study the Ansys UPFs user subroutines.
My problem is that how can I write an user subroutine for user defined dynamic loads act on a structure. Then the transient dynamic analysis can be done.
I have read the ansys user programmer's mannual. But I am not so clear about how to do?


Who can give me some suggestions?
thanks!
