Thank you so much Prof. for your quick reply
I am trying the two first proposed solution but it dosn't work.
For the third, in elmt25, I am using the following form for moving to isw:
goto (1,2,3,4,5,3,2,8,2,2,2,2,13,2,2), isw
...
return
there is any problem in this form?
It is important to note that the elmt25 work in old feap (FEAP7) !!
So if any one tel me the difference between the two Feap versions (in structure input or element); I think that solve the problem ?
I will apreciate any help
Thank's in advance for help
Best regard
