Dear Professor Taylor and dear FEAP Admin,

I am applying a triangular distributed load on a face of the vertical wall in 2d using Csurf command.

The height on which this distributed load is applied should change with time.

For example the parameter y should change with time until it reaches to the top of the wall.

csur
norm
linear
1  10  y     0
2  10 10   -f 

I have tried fprop using many props but there i don't get desired distribution of loads and it is not smooth variation :(
Should i have to change boundary conditions during solution? I am relatively new to feap and don’t have knowledge about macro file etc.
It will be really grateful if you could guide me to solve this problem.

Thanking you in advance.

Prof. R.L. Taylor

Look at using load groups
