Topic: Question about PiecewiseLinFunction: No success in solving problem
Hi,
I'm using PiecewiseLinFunction to define my loading.
When I use " PiecewiseLinFunction 1 t 3 0. 5 10 f(t) 3 0. -1 -0.001 ", it works well.
But when I change it to " PiecewiseLinFunction 1 t 3 0. 5 10 f(t) 3 0. -1 0.001 ", it can not calculate.

I tried with several different combinations and change the number of steps, but it seems that I can use either only negative values or only positive values in f(t) array so that I can get some solutions.
Could you tell me why?
Thank you very much!
